16-Port 10-Gigabit Ethernet MPC on MX Series Routers (16x10GE 3D MPC) Overview

In Junos OS Release 10.1 and later, MX960, MX480, and MX240 routers support the 16-port 10-Gigabit Ethernet MPC (16x10GE 3D MPC) with model numbers MPC-3D-16XGE-SFPP-R-B and MPC-3D-16XGE-SFPP. This MPC provides scalability in bandwidth, subscribers, and services capabilities of the routers.

The following are some of the key features of the 16x10GE 3D MPC:

  • Contains 16 built-in 10-Gigabit Ethernet ports in groups of four each. It does not contain separate slots for Modular Interface Cards (MICs).

  • Supports LAN-PHY mode with the following throughput:

    • 120 Gbps on Junos release 11.3 and earlier (SCB)

    • 160 Gbps on Junos release 11.4 and later (SCBE)

    • 160 Gbps on Junos release 13.3 and later (SCBE2)

    Note

    The 16x10GE 3D MPC does not support WAN-PHY mode.

  • Supports small form-factor pluggable transceivers of the SFP+ standard. For a list of supported SFPs, see the MX Series Interface Module Reference.

  • Supports an effective line rate of twelve 10-Gigabit Ethernet ports. If all sixteen 10-Gigabit Ethernet ports are used, the line card is oversubscribed in the ratio of 4:3.

  • Supports intelligent oversubscription services.

  • Supports one full-duplex 10-Gigabit Ethernet tunnel interface for each Packet Forwarding Engine.

For information about the supported and unsupported Junos OS features for this MPC, see “Protocols and Applications Supported by MX Series MPCs” in the MX Series Interface Module Reference.

Configuring the Number of Active Ports on 16-Port MPCs of MX Series Routers

You can disable a sub-set of the physical ports available on the Packet Forwarding Engines of the 16x10GE 3D MPC, and for PICs installed in MPC3, MPC4, MPC5, and MPC6.

Two of the most common reasons for disabling ports are explained below.

  • Ensure guaranteed bandwidth by preventing oversubscription—The 16x10GE 3D MPC supports one 10-Gigabit Ethernet tunnel interface for each Packet Forwarding Engine. The effective line-rate bandwidth of the MPC is 12 ports because of an oversubscription ratio of 4:3. Therefore, configuring a tunnel interface might further result in the Packet Forwarding Engines being oversubscribed. To prevent such oversubscription and to ensure a guaranteed bandwidth, include the number-of-ports configuration statement to disable one or two ports per Packet Forwarding Engine.

  • Enable Switch Control Board (SCB) redundancy—For maximum bandwidth capabilities (12-port line-rate bandwidth), the 16x10GE 3D MPC uses all the available SCBs (three SCBs for an MX960 router, two SCBs for an MX480 or MX240 router) actively in the chassis.

    If SCB redundancy (2+1 SCBs on an MX960 router or 1+1 SCB on an MX480 or MX240 router) is required, ports on the line card can be disabled by setting the number of usable ports per line card to 8. In such a case, the third and fourth ports (ports 0/2-3, 1/2-3, 2/2-3, 3/2-3) on every Packet Forwarding Engine are disabled.

To configure the number of active ports on the 16x10GE 3D MPC, include the number-of-ports active-ports configuration statement at the [edit chassis fpc slot-number] hierarchy level:

To configure the number of active ports on a PIC in an MPC3, MPC4, MPC5, or MPC6, include the number-of-ports active-ports configuration statement at the [edit chassis fpc slot-number pic pic-number] hierarchy level:

Specify either 8 or 12 ports using this statement. When eight active ports are configured, two ports per Packet Forwarding Engine are disabled, and the LEDs on the MPC are set to yellow. When you specify 12 active ports, one port per Packet Forwarding Engine is disabled and the corresponding LED is set to yellow. When you do not include this statement in the configuration, all 16 default ports on the MPC are active.

Note
  • Committing the configuration after including the number-of-ports active-ports configuration statement brings down the Ethernet interfaces for all the ports on the MPC before the ports configuration becomes active.

  • A minimum of one high-capacity fan tray is necessary for meeting the cooling requirements of the MPC. The Junos OS generates a chassis yellow alarm recommending fan tray upgrade for optimal performance, if the MX router chassis contains an old fan tray.

For more information about the 16x10GE 3D MPC, see the MX Series Interface Module Reference.

MPC3E on MX Series Routers Overview

MX960, MX480, MX240, and MX2020 routers support the MPC3E (MX-MPC3E-3D) with two MIC slots. The MPC provides the connection between the customer’s Ethernet interfaces and the routing fabric of the MX Series chassis.

The MPC3E supports these MICs as field-replaceable units (FRUs):

The MPC3E also supports these legacy MICs:

Starting in JunosOS Release 18.3R1, on MX240, MX480, and MX960 routers, the MIC-MACSEC-20GE with SFP/SFP+ ports are supported on MPC3 and MPC3E line cards.

The MIC-MACSEC-20GE includes MACSEC-enabled ports with 256-bit encryption (GCM-AES-256 and GCM-AES-XPN-256). For more information, refer to Understanding Interface Naming Conventions for MIC-MACSEC-20GE.

The MPC3E requires the Enhanced MX Switch Control Board (SCBE) for fabric redundancy. You can also continue to use existing SCBs without fabric redundancy. The MPC interoperates with existing MX Series line cards, including Dense Port Concentrators (DPCs) and Modular Port Concentrators (MPCs).

You can also configure the 100-Gigabit Ethernet MIC (MIC3-3D-1X100GE-CFP) to interoperate with routers using the 100-Gigabit Ethernet PIC (Type 4 1X100GE PIC for STFPC4 FPC) by using the forwarding-mode statement with the sa-multicast option at the [edit chassis fpc slot pic slot] hierarchy level. For more information, see Configuring 100-Gigabit Ethernet MICs to Interoperate with Type 4 100-Gigabit Ethernet PICs (PD-1CE-CFP-FPC4) Using SA Multicast Mode.

The MPC3E is based on a new Juniper Networks chipset for increased scalability for bandwidth, subscribers, and service capabilities of the routers.

The MPC3E supports these key features:

  • 100-Gigabit Ethernet interfaces

  • Two separate slots for MICs

  • The following MICs:

    • MIC3-3D-1X100GE-CFP

    • MIC3-3D-1X100GE-CXP

    • MIC3-3D-10XGE-SFPP

    • MIC3-3D-2X40GE-QSFP

    • MIC-3D-8DS3-E3

  • Up to 100 Gbps per MIC slot

  • Up to 200 Gbps aggregate WAN bandwidth connectivity for the two MIC slots; the line card is oversubscribed in the ratio of 1.5:1.

  • Up to four full-duplex tunnel interfaces on the line card

  • Intelligent oversubscription services

  • Configuration of Virtual Chassis ports in an MX Series Virtual Chassis member router

    The MPC3E supports all MX Series Virtual Chassis features, including Layer 2 and IEEE 802.3ad link aggregation features. An MX Series Virtual Chassis configuration does not currently support the Spanning Tree Protocol (STP).

Note

On the MX960 router, FPC slot 0 and slot 11 are not NEBS compliant beyond 104°F (40°C) with MPC3E-3D-NG and MPC3E-3D-NG-Q. This is a cooling restriction.

For more information about supported Junos OS features on the MPC3E, see Protocols and Applications Supported by the MPC3E on MX Series Routers in the MX Series Interface Module Reference.

The MPC3E supports feature parity with the following software features:

  • Basic Layer 2 features and virtual private LAN service (VPLS) functionality

MPC4E on MX Series Routers Overview

In Junos OS Release 12.3R2 and later, MX2020, MX2010, MX960, MX480, and MX240 routers support a new MPC, MPC4E. MPC4E is a fixed-configuration MPC that provides scalability in bandwidth and services capability of the routers. MPC4E is available in two models—MPC4E-3D-32XGE-SFPP and MPC4E-3D-2CGE-8XGE.

Note

Both models of MPC4E are supported on the MX2020, MX2010, MX960, MX480, and MX240 routers with both normal-capacity and high-capacity power supplies and fan trays.

MPC4E does not support legacy SCBs. It interoperates with existing MX Series line cards, including Dense Port Concentrators (DPCs) and Modular Port Concentrators (MPCs).

MPC4E is a fixed-configuration MPC and does not contain separate slots for Modular Interface Cards (MICs). It contains two Packet Forwarding Engines (PFEs)—PFE0 hosts PIC0 and PIC1 while PFE1 hosts PIC2 and PIC3.

You can also configure the MPC4E to interoperate with routers that use the 100-Gigabit Ethernet PIC (Type 4 PIC on Type 4 FPC) by using the forwarding-mode statement with the sa-multicast option at the [edit chassis fpc slot pic slot] hierarchy level. For more information, see Configuring MPC4E (MPC4E-3D-2CGE-8XGE) to Interoperate with 100-Gigabit Ethernet PICs on Type 4 FPC Using SA Multicast Mode.

MPC4E supports:

  • Forwarding capability of up to 130 Gbps per Packet Forwarding Engine.

  • Small form-factor pluggable (SFP) and C form-factor pluggable (CFP) transceivers for connectivity.

  • Up to 260 Gbps of full-duplex traffic.

  • Intelligent oversubscription services.

  • WAN-PHY mode on 10-Gigabit Ethernet interfaces on a per-port basis.

  • Up to four full-duplex tunnel interfaces on each MPC4E.

Note

By default on MX480 routers, only 5 out of the 6 line-card slots can be populated with MPC4Es. By default on MX960 routers, only 10 out of the 11 line-card slots can be populated with MPC4Es. This is a power restriction of default operating mode which supports operation at 55°C ambient temperature. You can insert other line-cards in the remaining slots as long as the power budget is not exceeded. However, if ambient-temperature is configured to 25°C or 40°C, all the 6 slots of an MX480 can be populated with MPC4E, and all the 11 slots of an MX960 can be populated with MPC4E. For more information about power requirements, see Power Requirements for an MX480 Router, and Power Requirements for an MX960 Router.

Also, on the MX960 router, FPC slot 0 and FPC slot 11 are not NEBS compliant beyond 104°F (40°C). This is a cooling restriction.

For more information about the supported and unsupported Junos OS software features for this MPC, see Protocols and Applications Supported on the MPC4E for MX Series Routers in the MX Series Line Card Guide.

MPC5E on MX Series Routers Overview

In Junos OS Release 13.3R2 and later, MX2020, MX2010, MX960, MX480, and MX240 routers support a new MPC, MPC5E. MPC5E is a fixed-port MPC. On MX2020 and MX2010 routers, MPC5E is housed in an adapter card (ADC). MPC5E is available in the following models:

13.3R3

MPC5E supports the enhanced Switch Control Board (MX-SCBE) and MX-SCBE2 on MX240, MX480, and MX960 routers. MPC5E does not support the legacy SCB (MX-SCB). MPC5E supports the Switch Fabric Board (SFB) on MX2010 and MX2020 routers.

On MX240, MX480, and MX960 routers, the number of MPC5Es that can be supported depends on the power entry module (PEM) type. There are no such restrictions for MX2010 and MX2020 routers.

Note

On MX960 routers, all the MPC slots work with chassis temperature of up to 40°C (104°F). However, when the chassis temperature exceeds 40°C (104°F), slots 0 and 11 do not work with MPC3E-3D-NG, MPC3E-3D-NG-Q, MPC4E, and MPC5E.

MPC5E interoperates with existing MPCs but does not interoperate with existing DPCs, except the Multiservices DPC (MS-DPC). MX series routers do not support tunnel services PICs. MPC5E provides support for inline tunnel interfaces and supports the following tunnel types:

  • Generic Routing Encapsulation (GRE) Tunnels

  • Multicast Tunnels (MT)

  • IP-IP Tunnels

  • Protocol Independant Multicast (PIM) E tunnels

  • Virtual loopback Tunneling (VT)

  • Logical Tunnelling (LT)

Note

On MX240, MX480, and MX960 routers, MPC5E powers on only if the network-services mode on the router is configured to either enhanced-ip or enhanced-ethernet. On the MX2010 and MX2020 routers, enhanced-ip is the only network-services mode supported.

MPC5E supports:

  • Forwarding capability of up to 130 Gbps per Packet Forwarding Engine

  • Flexible Queuing Mode using an add-on license

  • Intelligent oversubscription services

  • Optical Channel Transport Network services

  • Quad small form-factor pluggable plus transceivers (QSFP+) and small form-factor pluggable transceivers (SFP) for connectivity

  • Up to 240 Gbps of full-duplex traffic

  • WAN-PHY mode on 10-Gigabit Ethernet interfaces on a per-port basis

For more information about the supported and unsupported Junos OS software features for this MPC, see Protocols and Applications Supported by the MPC5E for MX Series Routers in the MX Series Interface Module Reference.

Guidelines for Identifying Active PICs on MPC5E (MPC5E-40G10G)

MPC5E contains two Packet Forwarding Engines (PFEs) and 4 fixed port PICs. On MPC5E-100G10G, the PFE0 hosts PIC0 and PIC1 while PFE1 hosts PIC2 and PIC3. All the PICs can be powered on and used.

On the MPC5E-40G10G, the PFE0 hosts PIC0 and PIC2 while PFE1 hosts PIC1 and PIC3. Only a maximum of two PICs (PIC0 or PIC2 and PIC1 or PIC3) can be powered on. The remaining PICs are required to be kept powered off.

This topic describes the guidelines to consider while identifying active PICs on the MPC5E (MPC5E-40G10G):

  • By default, (i.e. without any CLI configuration), PIC0 (12x10GE) and PIC1 (12x10GE) are powered ON while PIC2 (3x40GE) and PIC3 (3x40GE) shall be powered OFF.

  • At least one PIC on every PFE should be configured in power OFF state. PIC0 and PIC2 belong to PFE0 and PIC1 and PIC3 belong to PFE1 .

  • If you configure an invalid PIC combination, the default PICs (PIC0 and PIC1) will be powered ON. Also, a syslog message is displayed to indicate the invalid PIC combination selected. When you configure an invalid PIC combination, and commit the change, the commit succeeds and a commit failure message is not displayed.

Table 1 lists the active PICs on MPC5E-40G10G based on the configuration.

MPC7E (Multi-Rate) on MX Series Routers Overview

In Junos OS Release 15.1F4 and later, MX2020, MX2010, MX960, MX480, and MX240 routers support the rate-selectable MPC MPC7E (Multi-Rate) (model number: MPC7E-MRATE). The MPC7E-MRATE MPC is a fixed-configuration MPC that provides scalability in bandwidth and services capability of the routers.

The main features of the MPC7E-MRATE MPC are the following:

  • Line-rate throughput of up to 480 Gbps on MX240, MX480, and MX960 routers.

  • Line-rate throughput of up to 400 Gbps on the MX2000 line of routers.

  • Twelve ports that can each be configured as a 40-Gigabit Ethernet port or as four 10-Gigabit Ethernet ports by using a breakout cable. The ports support quad small-form factor pluggable plus (QSFP+) transceivers.

  • Four ports—0/2, 0/5, 1/2, and 1/5—out of the twelve ports can be configured as 100-Gigabit Ethernet ports.

  • By default, the ports are configured as 10-Gigabit Ethernet ports.

  • You can configure different combinations of port speeds as long as the aggregate capacity per group of six ports labeled 0/0 through 0/5 does not exceed 240 Gbps. Similarly, aggregate capacity per group of the other six ports labeled 1/0 through 1/5 must not exceed 240 Gbps.

For information about the supported and unsupported Junos OS features for this MPC, see Protocols and Applications Supported by the MPC7E for MX Series Routers in the MX Series Line Card Guide.

MPC7E-MRATE Gigabit Ethernet Interface Naming Convention

The MPC7E-MRATE MPC is a fixed-configuration MPC and does not contain separate slots for Modular Interface Cards (MICs). It contains two PICs, PIC 0 and PIC 1. Each PIC has six physical quad small form-factor pluggable plus (QSFP+) ports that support 100-Gbps, 10-Gbps, or 40-Gbps port speeds. You use the 4x duplex LC breakout cables and fiber-optic 40-gigabit and 100-gigabit QSFP+ transceivers to achieve these speeds.

Tip

You can issue the show chassis pic fpc-slot fpc-slot-number pic-slot pic-slot-number command to view the supported speeds on each port.

Each of the six ports of PIC 0 and PIC 1 supports 10-Gigabit and 40-Gigabit Ethernet interfaces. However, only ports 2 and 5 on both the PICs support 100-Gigabit Ethernet interfaces. The 40 and 100 Gigabit Ethernet interfaces configured on the MPC7E-MRATE MPC follow the naming convention et-fpc-slot/pic-slot/port-number. For example, et-0/0/2 indicate a 40-Gigabit or 100-Gigabit Ethernet interface configured on port 2 of PIC 0 of the MPC7E-MRATE MPC that is installed in the FPC slot 0.

You can configure four 10-Gigabit Ethernet interfaces on each port. Therefore, the 10 Gigabit Ethernet interfaces configured on the MPC7E-MRATE MPC follow the naming convention xe-fpc-slot/pic-slot/port-number:channel-number. Channel numbers 0 to 3 are used to indicate the four logical ports that are enabled by the use of the 4x duplex LC breakout cables. Therefore, the four 10-Gigabit Ethernet interfaces that are configured on port 2 of PIC 0 of an MPC7E-MRATE MPC that is installed in the FPC slot 0 is as follows:

  • xe-0/0/2:0

  • xe-0/0/2:1

  • xe-0/0/2:2

  • xe-0/0/2:3

MPC7E-MRATE MPC Rate-Selectability Overview

You can choose to configure all supported ports of the PIC to operate at the same speed or configure all the ports at different supported speeds. For example, you can choose to configure:

  • All the ports of the PIC at 10-Gbps speed.

  • All the ports of the PIC at 40-Gbps speed.

  • Ports 2 and 5 of the PIC at 100-Gbps speed.

  • Ports 0, 1, 3, 4 of the PIC at 10-gigabit or 40-gigabit speed and ports 2 and 5 at 100-gigabit speed.

To configure all ports to operate at the same speed, you configure rate selectability at the PIC level. When you configure rate selectability at the PIC level, all the ports of the PIC that support the configured speed operate at that speed. Additionally, you can configure the number of active ports that operate at the configured speed. That is, for example, if you want only two ports of the PIC to operate at 40-gigabit speed, you can configure the PIC to operate at 40-gigabit speed and enable the two ports that you want to operate at that speed. The remaining four ports of the PIC are automatically disabled. Configuring rate selectability at the PIC level helps you configure the operating speed of the PIC easily.

To configure different ports of the PIC to operate at different supported speeds, you configure rate selectability at the port level. You configure each port of the PIC to operate at a specific supported speed. Only the ports that are configured are enabled, while the other ports are automatically disabled. Configuring rate selectability at the PIC level provides you the flexibility of operating the ports of the PIC at different supported speeds. For example, you can configure four 10-Gigabit Ethernet interfaces on port 0, one 40-Gigabit Ethernet interface on port 1, and one 100-Gigabit Ethernet interface on port 2.

Note
  • Ensure that you connect optics to the ports according to the speeds that you configure. That is, you have to use 4x duplex LC breakout cables to configure 10-Gigabit Ethernet interfaces, fiber-optic 40-gigabit QSFP+ transceivers to configure 40-Gigabit Ethernet interfaces, and fiber-optic 100-gigabit QSFP28 transceivers to configure 100-Gigabit Ethernet interfaces.

  • If rate selectability is not configured, each port of the MPC7E-MRATE MPC operates as four 10-Gigabit Ethernet interfaces.

For more information about how to configure rate selectability, see Configuring Rate Selectability on MPC7E (Multi-Rate) to Enable Different Port Speeds.

MPC7E 10G on MX Series Routers Overview

Starting with Junos OS Release 15.1F5, MX2020, MX2010, MX960, MX480, and MX240 routers support the Modular Port Concentrator (MPC) MPC7E 10G (MPC7E-10G). This is a fixed-configuration MPC with forty 10-Gbps Ethernet ports. To use the MPC7E 10G MPC on Junos OS Release 15.1F5, you must download and install the Junos Continuity software package for Junos OS Release 15.1F5.

Note

  • On MX2000 line of routers, MPC7E 10G is plugged into an adapter card. Therefore, to use the MPC7E 10G MPC on MX2000 line of routers, the adapter card must be installed on the routers.

  • To operate MPC7E 10G on MX240, MX480, and MX960 routers, the routers must be equipped with high-capacity power supply, high-capacity fan tray, and Enhanced Switch Control Board SCBE2.

The main features of the MPC7E-MRATE MPC are the following:

  • Line-rate throughput of up to 400 Gbps on MX240, MX480, MX960, MX2010, and MX2020 routers.

  • Forty 10-Gigabit Ethernet ports. The ports support small-form factor pluggable plus (SFP+) transceivers.

  • Support maximum transmission units (MTUs) from 256 bytes through 16,000 bytes.

  • Supports Hyper mode to speed up packet processing.

  • Supports Flexible queuing using an add-on license to support 32,000 queues per line card, including queues on both ingress and egress interfaces. You can use an additional license to support up to 512,000 queues.

Note

On MX240, MX480, and MX960 routers, MPC7E 10G powers on only if the network-services mode on the router is configured as either enhanced-ip or enhanced-ethernet. On MX2000 routers, no additional configuration is required because by default the router operates in enhanced-ip mode.

For information about the supported and unsupported Junos OS features for this MPC, see Protocols and Applications Supported by the MPC7E for MX Series Routers in the MX Series Line Card Guide.

MPC8E on MX Series Routers Overview

In Junos OS Release 15.1F5 and later, MX2020 and MX2010 routers support MPC8E (model number: MX2K-MPC8E), a new Modular Port Concentrator (MPC) with two Modular Interface Card (MIC) slots that provide a maximum bandwidth of 960 Gbps. . Each MIC slot on MPC8E supports a 12-port rate selectable MIC (MIC-MRATE). MPC8E has four Packet Forwarding Engines, each providing a maximum bandwidth of 240 Gbps.

Note

To use the MPC8E MPC on Junos OS Release 15.1F5, you must download and install the Junos Continuity software package for Junos OS Release 15.1F5.

MPC8E plugs into the chassis and provides the fabric interface. The MX2000 line of routers can support eight Switch Fabric Boards (SFBs) and eight Enhanced Switch Fabric Boards (SFB2s) but not both at the same time. However, during an upgrade from SFB to SFB2, the MX2000 line of routers support both SFB and SFB2 at the same time for the duration of the upgrade.

Starting in Junos OS Release 17.4R1, MIC-MACSEC-MRATE with MACsec is supported on MPC8E to extend MACsec capabilities on MX2000 line of routers (MX2020, MX2010, MX2008). The MACsec feature increases the Data Center (DC) security and also for DC to DC secured connectivity. MIC-MACSEC-MRATE MIC enable 40G and 100G MACsec capability to the MPC8E. . Each MPC supports two MIC-MACSEC-MRATE MICs. On an MPC8E, each MIC supports 48 10-Gigabit Ethernet, 12 40-Gigabit Ethernet, or 4 100-Gigabit Ethernet MACsec-capable interfaces, or a combination.

Note

Compared to other MICs, MIC-MACSEC-MRATE takes longer time (around 4 minutes) to boot as it is required to bring up two MICs in serial.

MPC8E supports:

  • Line-rate throughput of up to 960 Gbps on the MX2000 line of routers.

  • MIC-MRATE MICs with QSFP+ transceivers that support rate selectability at the port level and at the MIC level.

  • Configuration of 4 ports out of the 12 MIC-MRATE ports as 100-Gigabit Ethernet ports.

  • Configuration of PIC-based tunnel interfaces from the Junos OS CLI.

  • Maximum transmission unit (MTU) size of 16,000 bytes for transit traffic.

MPC8E supports the following software features:

For more information about the supported and unsupported Junos OS features on MPC8E, see Protocols and Applications Supported by the MPC8E and MPC9E on the MX2010 and MX2020 Routers in the MX Series Interface Module Reference.

Upgrading MPC8E to Provide Increased Bandwidth

In Junos OS Release 16.1R1 and later, you can upgrade MPC8E to provide an increased bandwidth of 1600 Gbps (1.6 Tbps) by using an add-on license. After you purchase the license and perform the upgrade, MPC8E provides a bandwidth of 1.6 Tbps, which is equivalent to the bandwidth that MPC9E provides. However, the MPC continues to be identified as MPC8E.

Note

After you upgrade MPC8E to provide a bandwidth of 1.6 Tbps, the power consumption by MPC8E increases and is equivalent to the power that MPC9E consumes. See MPC8E for more information.

After you purchase the add-on license, you upgrade the bandwidth by using the set chassis fpc slot bandwidth 1.6T command. You can disable this feature by using the delete chassis fpc slot bandwidth 1.6T command.

Note

When you modify the bandwidth of MPC8E and commit the configuration, the MPC automatically reboots . For instance, if you upgrade MPC8E to provide a bandwidth of 1.6 Tbps and commit the configuration, the MPC automatically reboots. Also, if you disable the feature on MPC8E (to provide a bandwidth of 960 Gbps) and commit the configuration, the MPC automatically reboots.

MPC9E on MX Series Routers Overview

In Junos OS Release 15.1F5 and later, the MX2000 line of routers support a new modular MPC, MPC9E (MX2K-MPC9E). MPC9E has two Modular Interface Card (MIC) slots. MPC9E has four Packet Forwarding Engines, each with forwarding capacity of up to 400 Gbps. MPC9E supports only the 12-port, rate-selectable MIC (MIC-MRATE).

Note

To use the MPC9E MPC on Junos OS Release 15.1F5, you must download and install the Junos Continuity software package for Junos OS Release 15.1F5.

Starting in Junos OS Release 17.4R1, MIC-MACSEC-MRATE with MACsec is supported on MPC9E to extend MACsec capabilities on MX2000 line of routers (MX2020, MX2010, MX2008). The MACsec feature increases the Data Center (DC) security and also for DC to DC secured connectivity. Each MPC supports two MIC-MACSEC-MRATE MICs. On an MPC9E, each MIC supports 48 10-Gigabit Ethernet, 12 40-Gigabit Ethernet, or 8 100-Gigabit Ethernet MACsec-capable interfaces, or a combination.

Note

Compared to other MICs, MIC-MACSEC-MRATE MIC takes longer time (around 4 minutes) to boot as it is required to bring up two MICs in serial.

MPC9E plugs into the chassis and provides the fabric interface. MX2000 line of routers can support eight Switch Fabric Boards (SFB) and eight Enhanced Switch Fabric Boards (SFB2) but not both at the same time. However, during an upgrade from SFB to SFB2, the MX2000 line of routers support both SFB and SFB2 at the same time for the duration of the upgrade.

  • Line-rate throughput of up to 1.6 Tbps on the MX2000 line of routers.

  • MIC-MRATE MICs with QSFP+ transceivers that support rate selectability at the port level and at the MIC level.

MX10003 MPC on MX10003 Router Overview

In Junos OS Release 17.3R1 and later, the MX10003 router supports a new Modular Port Concentrator (MPC), MX10003 MPC. Each MPC supports a Multi-Rate 12xQSFP28 Ethernet Modular Interface Card (MIC) (model numbers: JNP-MIC1 (in Junos OS Release 17.3R1) and JNP-MIC1-MACSEC (in Junos OS Release 17.3R2)) and the fixed-port PIC (6xQSFPP). The router provides two dedicated line-card slots for MPCs. MPCs install into the line-card slots. The fixed-port PIC is mapped to PIC 0, and each Packet Forwarding Engine is mapped to two ports in PIC 0. The Multi-Rate 12xQSFP28 Ethernet MIC is mapped to PIC 1, and each Packet Forwarding Engine is mapped to four ports in PIC 1. On the MIC all 12 ports are active and are capable of running in 40-Gigabit Ethernet, 100-Gigabit Ethernet, and 4x10-Gigabit Ethernet mode.

The MX10003 MPC supports:

  • Line-rate throughput of up to 1.2 Tbps on the MX10003 routers.

  • MICs with QSFP+/QSFP28 transceivers that are rate-selectable at the port level and at the MIC level.

  • Configuration of all 12 ports of the MIC as 100-Gigabit Ethernet ports.

  • Configuration of PIC-based tunnel interfaces from the Junos OS CLI.

  • Maximum transmission unit (MTU) size of 16,000 bytes for transit traffic.

The MX10003 MPC supports the following software features:

MPC and MIC Lane LED Scheme Overview

LEDs on the interface cards display the status of the ports. On some MICs and MPC that have multiple ports and supports multiple port speed, it is not feasible to have an individual LED display for each port on an interface card. Hence, a shared LED display is introduced—the lane LEDs.

The MX10003 MPC includes this new LED lane display. The Multi-Rate 12xQFSP28 MIC and the fixed-port PIC (6xQFSPP) have separate lane LEDs.

The lane LEDs of the MIC are located on the MIC itself, whereas the lane LEDs of the PIC are located on the MPC.

The following interface cards support lane LEDs:

You can select a port operating in a breakout mode for an individual lane display, either periodically or when the request chassis port-led command is executed. Similar to the port status LEDs, the lane LED supports 4 states defined by the color or the LED status—OFF, GREEN, AMBER, and RED.

Figure 1 illustrates the port LED and lane LED displays on the MPC.

Port LEDs

The following port LED display modes are defined:

  • Normal—The port status LED represents port state or a breakout port state. By default, the port status display mode is Normal.

  • Lane display—An array of lane status LEDs displays the status of each individual lane for the selected port. The lane display is ON when the software cycles through ports for lane status display. One port is selected at a time, and the display mode for that particular port switches to lane display mode. The other ports remain in normal display mode.

  • Port location—The port location mode is ON when a remote operator initiates a port location command for a port or a group of ports. The request chassis port-led command temporarily overrides periodic software port selection for the lane display; all ports on an interface card that are not selected for port location switch to Normal mode, and selected ports switch to port location mode. If only one port is selected for port location, then the corresponding lane LEDs are applicable. However, if the selected port is in breakout mode, then all lane LEDs are applicable. If not in breakout mode, only lane 0 LED displays the port status. If more than one port is selected for port location, then the lane LEDs are disabled.

The following factors trigger a change in the port LED color:

  • Change in the port state. For example, loss of signal (LOS) to no LOS, remote fault, or local fault

  • Pluggable insertion or removal

  • Change in configuration

  • Activation or deactivation of port location feature

  • Selection of breakout port for lane display

Note

Ports with all individual links in Up state are skipped and are not considered for lane display, thereby reducing the time needed to cycle through all the ports.

Table 2 summarizes the state and color rules for the port LEDs. These rules help in determining the port LED color. When port location mode is activated, the port LED state or color can be determined from the Port Location ON column. If the breakout port is selected for the lane status display, then port LED state or color can be determined from the Lane Display column.

JNP10K-LC2101 MPC on MX10008 Routers Overview

In Junos OS Release 18.2R1 and later, MX10008 routers support a new MPC, JNP10K-LC2101. JNP10K-LC2101 is a fixed-configuration MPC that provides increased port density and performance to the MX10008 routers. JNP10K-LC2101 does not contain separate slots for Modular Interface Cards (MICs) and has six Packet Forwarding Engines.

MX10008 routers support eight JNP10K-LC2101 MPCs. By default, each JNP10K-LC2101 MPC provides a maximum bandwidth of 2.4Tbps. JNP10K-LC2101 has six Packet Forwarding Engines, each providing a maximum bandwidth of up to 400 Gbps, which cannot be oversubscribed. JNP10K-LC2101 MPC plugs into the chassis and provides the fabric interface. The MX10008 router supports six Switch Fabric Boards (SFBs).

The MX10008 router supports only enhanced-ip and enhanced-ethernet network services mode. The default network services mode is enhanced-ip.

JNP10K-LC2101 supports:

  • Multi-rate ports. The ports on the JNP10K-LC2101 MPC support multiple port speeds such as 10Gbps, 40 Gbps, and 100 Gbps. Hence, they are known as multi-rate ports. All ports support all port speeds. To view the port speed information for each port, use the show chassis pic fpc-slot fpc-slot-number pic-slot pic-slot-number command.

  • PIC-based tunnel configuration

  • Maximum Transmission Unit (MTU) size of 16000 bytes for transit traffic.

  • Dynamic Power Management for effective utilization of available power.

  • Flexible queuing supports 128,000 queues per line card, including queues on both ingress and egress interfaces. You can use an additional license to support up to 256,000 queues or 1,500,000 queues per slot.

For more information about the supported and unsupported Junos OS features on JNP10K-LC2101, see Protocols and Applications Supported by the JNP10K-LC2101 on the MX10008 Routers in the MX Series Interface Module Reference.

Downgrading JNP10K-LC2101 to Provide Decreased Bandwidth

You can downgrade the JNP10K-LC2101 MPC to provide a decreased bandwidth of 1.44Tbps. After you perform the downgrade, JNP10K-LC2101 provides a bandwidth of 1.44Tbps. Each of the six Packet Forwarding Engines now provide a maximum bandwidth of up to 240 Gbps, which cannot be oversubscribed.

You can downgrade the bandwidth by using the set chassis fpc slot bandwidth 1.44T command. You can disable this feature by using the delete chassis fpc slot bandwidth 1.44T command.

Note

When you modify the bandwidth of JNP10K-LC2101 and commit the configuration, the MPC automatically reboots . For instance, if you downgrade JNP10K-LC2101 to provide a bandwidth of 1.44 Tbps and commit the configuration, the MPC automatically reboots. Also, if you disable the feature on JNP10K-LC2101 (to provide a bandwidth of 2.4Tbps) and commit the configuration, the MPC automatically reboots.

MX204 Router Overview

Starting with Release 17.4R1, Junos OS supports the MX204 Universal Routing Platform (model number: JNP204 [MX204]). The MX204 chassis is a monolithic system— that is, it does not have separate Switch Processor Mezzanine Boards and line cards. All the router components including Packet Forwarding Engines and WAN interfaces are managed by the CPU subsystem (consisting of an eight-core Broadwell CPU). The MX204 delivers a throughput of up to 400 Gbps.

The MX204 router is a fixed-configuration router, and supports one fixed Routing Engine. It contains a total of twelve fixed ports, in two groups of four and eight, respectively. The set of four ports (referred to as the PIC 0 ports) are rate selectable and can be configured at 10-Gbps (by using a breakout cable), 40-Gbps, or 100-Gbps speed. However, not all the ports support all the three speeds. The set of eight ports (referred to as PIC 1 ports) operate at a fixed speed of 10-Gbps. The four rate-selectable ports support QSFP28 and QSFP+ transceivers, whereas the eight 10-Gigabit Ethernet ports support SFP+ transceivers.

See MX204 Router Rate-Selectability Overview and Supported Active Physical Rate-Selectable Ports to Prevent Oversubscription on MX204 Router for more details.

MX204 LED Scheme Overview

LEDs on the interface cards display the status of the ports. In MX204 router, there are four port LEDs per port. Each port provides an individual status LED with four states signaled by the color/LED state: OFF, GREEN, AMBER, RED.

The following port LED display modes are defined:

  • Normal—Represents the normal working mode of the LED. By default, the port status display mode is Normal.

  • Port location—The port location mode is ON when a remote operator initiates a port location command for a port or a group of ports.

The following factors trigger a change in the port LED color:

  • Change in the port state. For example, loss of signal (LOS) to no LOS, remote fault, or local fault

  • Pluggable insertion or removal

  • Change in configuration

  • Activation or deactivation of port location feature

Table 4 summarizes the state and color rules for the port LEDs. These rules help in determining the port LED color. When port location mode is activated, the port LED state or color can be determined from the Port Location ON column.

Note

In MX204 router, there are four port LEDs per port. On PIC 0, if the port operates at the speed of 40-Gbps or 100-Gbps, then the first LED of PIC 1 will be ON and the other three LEDs will be OFF. And, if the port operates at the speed of 10-Gbps, then all the LEDs will be ON.

MPC10E-15C-MRATE Overview

Starting with Junos OS Release 19.1R1, the MX240, MX480 and MX960 routers support MPC10E-15C-MRATE (15x100GE) line card. This fixed-port line card is capable of delivering a bandwidth of up to 1.5 Tbps per MPC slot. It supports three MICs (one per Packet Forwarding Engine), each of which can deliver a throughput of up to 500 Gbps. Each MIC comprises five ports that support 100 Gbps (the default), 40 Gbps, and 10 Gbps speeds through the use of QSFP28+ and QSFP+ optics. You can enable 10 Gbps speed (four 10 Gbps channels) by using breakout cables.

MPC10E-15C-MRATE supports a maximum transmission unit (MTU) starting from 256 bytes to 16,000 bytes for transit traffic, and from 256 bytes to 9,500 bytes for host bound packets.

The MPC10E-15C-MRATE line card supports both hyper mode and normal mode. However, the default mode for MPC10E is hyper mode. For more details about hypermode, see Understanding the Hyper Mode Feature on Enhanced MPCs for MX Series Routers and EX9200 Switches.

Note
  • The MPC10E-15C-MRATE is powered on only if the MX Series router has an enhanced Switch Control Board (SCBE3) installed.

  • The MPC10E-15C-MRATE is powered on only if the router operates in enhanced-ip or enhanced-ethernet mode.

  • The MPC10E-15C-MRATE will be powered on only when the MX Series router is installed with enhanced Fan Trays.

  • The MPC10E-15C-MRATE will be supported only when the MX Series router is installed with Enhanced PEMs.

  • On MX960 routers with enhanced Midplane on the slot 1, the MPC10E-15C-MRATE will not be powered on.

Note

Fabric Management on MPC10E-15C-MRATE

The MPC10E line cards function only if the MX router has an SCBE3 installed. The MPC10E-15C-MRATE supports the following two fabric redundancy modes:

  • redundant mode

  • increased bandwidth mode

On MX Series routers with MPC10E-15C-MRATE, the default fabric redundancy mode is increased bandwidth mode. To configure the MPC10E-15C-MRATE to function in redundant fabric mode, use the existing redundancy-mode redundant statement at the [edit chassis fabric] hierarchy level. To configure the MPC10E-15C-MRATE to function in increased bandwidth mode, use the redundancy-mode increased-bandwidth statement at the [edit chassis fabric] hierarchy level. In a redundant configuration, an MPC10E line card provides a fabric bandwidth of up to 1 Tbps. In a non-redundant configuration, an MPC10E-15C-MRATE supports a fabric bandwidth of up to 1 Tbps (with four fabric planes) and 1.5 Tbps fabric bandwidth when all six fabric planes are used.

Fabric bandwidth supported by MPC10E-15C-MRATE with SCBE3 is as follows:
