PTX10008 Line Card Components and Descriptions

PTX10K-LC1101 Line Card

• Overview

• Channelizing 40-Gigabit Ethernet Ports

• Network ports

Overview

The PTX10K-LC1101 line card consists of 30 quad small form-factor pluggable (QSFP28) cages that support either 40-Gigabit Ethernet or 100-Gigabit Ethernet optical transceivers; see Figure 1. The PTX10K-LC1101 line cards also support 10-Gigabit Ethernet interfaces. For 10-Gigabit Ethernet, you must configure the port using the channelization-speed command. By default, the interfaces are created with 100-Gbps port speed. If the user plugs in a 40GE or 4*10GE transceiver, you must configure the appropriate port speed manually using the CLI.

The PTX10K-LC1101 line card runs Juniper Networks Junos OS for PTX Series software on Juniper Networks PTX10K-LC1101 hardware. The PTX10K-LC1101 line card is supported on Junos OS Release 17.2R1 and later.

2 — Network ports

Each network port can operate as a:

• 100-Gigabit Ethernet port when you use QSFP28 optical transceivers.

• 40-Gigabit Ethernet port when you use QSFP+ optical transceivers.

To change from the default mode (100-Gigabit Ethernet) to 40-Gigabit Ethernet channelized mode, use the Junos OS operational command set chassis fpc slot-number pic 0 port port number channelization-speed 10g.

Channelizing 40-Gigabit Ethernet Ports

Each of the 40-Gigabit Ethernet ports on the PTX10K-LC1101 line card can be channelized into four 10-Gigabit Ethernet, or channels. When ports are in channelization mode, the fourth port on each Packet Forwarding Engine is disabled, and the remaining four ports that are mapped to the same Packet Forwarding Engine can be used as either 4x10-Gigabit Ethernet, 40-Gigabit Ethernet, or 100-Gigabit Ethernet ports. The channelization mode works independently for each of the Packet Forwarding Engines on the PTX10K-LC1101 line card. See Figure 2 to see which ports are disabled and see Table 3 for the maximum port configurations.

Figure 2: Disabled Ports in Channelization Mode

Unlike the PTX10K-LC1102 line card, the PTX10K-LC1101 line card does not have port groups; instead, port behavior is tied to the ASIC associated with the port. You must configure each port individually, in order to channelize a 40-Gigabit Ethernet port to 4 independent 10-Gigabit Ethernet ports. For example, ASIC PE0 maps to ports 0, 2, 4, 6, and 8. The fourth port, port 6, is disabled. See Table 4 for the list of available ports and the associated ASIC mapping in Figure 2 to locate the available and disabled ports.

Network ports

Each of the 30 QSFP28 ports supports:

• 100-Gigabit Ethernet using QSFP28 optical transceivers.

• 40-Gigabit Ethernet using QSFP+ optical transceivers.

• 40-Gigabit Ethernet to 10-Gigabit/1-Gigabit QSFP-to-SFP adapter (QSA) (Junos OS Release 18.4R1 and later).

PTX10K-LC1102 Line Card

• Overview

• Network Ports

• Channelization

• Port Status and Activity LEDs

Overview

The PTX10K-LC1102 line card consists of 36 quad small form-factor pluggable plus (QSFP+) ports that support 40-Gigabit Ethernet optical transceivers. Out of these 36 ports, 12 ports can also support 100-Gigabit Ethernet QSFP28 transceivers. The PTX10K-LC1102 line cards also support 10-Gigabit Ethernet interfaces. You can channelize 40-Gigabit Ethernet ports to four independent 10-Gigabit Ethernet interfaces by configuring the port speed and cabling the port using fiber breakout cables. See Figure 3.

The PTX10K-LC1102 line card runs Juniper Networks Junos OS for PTX Series software on Juniper Networks PTX10K-LC1102 hardware. The PTX10K-LC1102 line card is supported on Junos OS Release 17.2R1 and later.

2 — Network ports

Each QSFP28 port can be configured as:

• 100 m-Gigabit Ethernet port using QSFP28 optical transceivers. Only the ports with a fine black line underneath the port are capable for 100-Gigabit Ethernet. When a QSFP28 transceiver is inserted into these ports and you configure the port for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 port is enabled for 100-Gigabit Ethernet.

• 40-Gigabit Ethernet port using QSFP+ optical transceivers.

• 10-Gigabit Ethernet port using breakout cabling and attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into four independent 10-Gigabit Ethernet channels.

Network Ports

Each of the 12 QSFP28 ports supports:

• 100-Gigabit Ethernet QSFP28 transceivers

• 40-Gigabit Ethernet QSFP+ transceivers

• 40-Gigabit Ethernet to 10-Gigabit/1-Gigabit QSA (Junos OS Release 18.4R1 and later)

Each of the 36 QSFP+ ports supports:

• 40-Gigabit Ethernet QSFP+ transceivers

• 40-Gigabit Ethernet to 10-Gigabit/1-Gigabit QSA (Junos OS Release 18.4R1 and later)

Channelization

Every second and sixth port in a 6xQSFP cage on a PTX10K-LC1102 line card supports 100-Gigabit Ethernet using QSFP28 transceivers. These 100-Gigabit Ethernet ports operate either as 100-Gigabit Ethernet ports or as 40-Gigabit Ethernet, but are recognized as channelized 4x10-Gigabit Ethernet by default. See Figure 4 for a closeup view of a 6xQSFP+ cage. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Ethernet port, the port recognizes the 40-Gbps port speed. When a 100-Gigabit Ethernet transceiver is inserted into the port and enabled in the CLI, the port recognizes the 100-Gbps speed and disables two adjacent 40-Gigabit Ethernet ports. See Figure 5 and Figure 6. You can also use a 100-Gigabit Ethernet transceiver and run it at 40-Gigabit Ethernet by using the CLI to set the port speed to 40-Gigabit Ethernet.

Figure 4 shows the default configuration of a cage of ports on the PTX10K-LC1102.

Figure 4: All Ports Are Enabled for Channelized 4x10-Gigabit Ethernet by Default

Figure 5: 100-Gigabit Ethernet Ports Can Operate at Either 100 Gbps or 4x10 Gbps Speeds

Figure 6: Enabled 100-Gigabit Ethernet Port Creates a Port Group and Disables the Associated 40-Gigabit Ethernet Port

The 40-Gigabit Ethernet ports can operate independently, be channelized into four 10-Gigabit Ethernet ports, or bundled with the next two consecutive ports and channelized into twelve 10-Gigabit Ethernet ports as a port range. Only the first and fourth port in each 6xQSFP cage are available to channelize a port range (see Figure 7). The port speed must be configured using the set chassis fpc pic port speed command. For example, to set the first router port as 40-Gigabit Ethernet (not channelized), use the set chassis fpc 0 pic 0 port 0 speed 40g command.

Figure 7: Use the First and Fourth Port in Each 6XQSFP Cage to Channelize a Port Range

Table 5 shows the available combinations for the ports. On the PTX10K-LC1102, the ports are enabled by default.

Port Status and Activity LEDs

Each network port has a bi-colored up or down LED indicator that show ports status and link activity based on whether or not the port is configured for channelization. See Figure 8, Table 6 and Table 7.

2 — Network link and Ethernet link LEDs

Each PTX10K-LC1104 has six physical interfaces (ot-x/x/x) that connect to one of three built-in flexible rate optical transponders for a maximum of 24 physical interfaces on a PTX10008 or PTX10016 system. Each transponder connects four 100-Gigabit Ethernet logical interfaces (et-x/x/x) to one of three forwarding ASICs. These forwarding ASICs are responsible for optional MACsec encryption on each 100-Gigabit Ethernet interface. See Figure 10.

Figure 10: PTX10K-LC1104 Interfaces

Each of the six network ports can operate in one of three modulation formats; see Table 8.

Compatibility

The Juniper Networks integrated DWDM solution includes integrated 100-Gigabit Ethernet coherent optics on Juniper Networks QFX Series Switches; MX Series 5G Universal Routing Platforms, and PTX Series Packet Transport Routers; and BTI Packet Optical Platforms optimized for DCI. As part of the Open Cloud Interconnect solution, the PTX10K-LC1104 coherent line card is compatible with many third-party optical products as well as Juniper Networks optical solutions and offerings. The PTX10K-LC1104 coherent line card is interoperable with the BTI Series Packet Optical Transport UFM6 in 100-Gbps and 200-Gbps modes. It is also compatible with the MX Series MICs and PTX Series PICs in 100-Gbps mode. See Table 9.

Optical Transmit Specifications

The line card is connected using single-mode fiber (SMF) and LC connectors. See Table 10 and Table 11 for the optical transponder specifications.

Optical Receive Specifications

Status and Activity LEDs

There are two types of LEDs for the network ports: port LEDs and Ethernet link LEDs. The LEDs for the six physical ports indicate the link state of an ot-interface. There are four LEDs in between each port pair that indicate the link state of the associated et-interfaces, (see Figure 11). To determine the link state of the ot-interface see Table 12.

Figure 11: DWDM Port and Ethernet Link State LEDs

1 — Port LEDs (ot-interfaces)

2 — Ethernet LEDs (et-link interfaces)

You can also determine the configuration of the et interfaces by examining the pattern of the four Ethernet LEDs. See Table 13. To determine the link status and of those et interfaces, see Table 14.

Optical and Ethernet Interface Alarms and Defects

Table 15 and Table 16 describe the ot and et interface alarms and defects that can occur on the line card and the link status when the alarm or defect occurs.

1.2-Terabyte Per Second DWDM OTN Module Wavelengths

Each of the 30 QSFP28 ports can operate as:

• 100-Gigabit Ethernet ports when you use QSFP28 optical transceivers.

• 40-Gigabit Ethernet ports when you use QSFP+ optical transceivers.

On the PTX10K-LC1105, the ports are enabled by default.

PTX10K-LC1201-36CD for PTX10008 Routers

• Overview

• Network Ports

• Channelization

• Network LEDs

• Line Card Status LEDs

Overview

The PTX10K-LC1201-36CD line card combines Packet Forwarding Engine based on Juniper Networks custom ASICs to deliver a 400GbE solution for data centers.. You can channelize the ports using breakout cables to speeds of 200-Gbps, 100-Gbps, 50-Gbps, 25-Gbps, or 10-Gbps. See Figure 14.

Figure 14: PTX10K-LC1201-36CD Port Panel

The PTX10K-LC1201-36CD line card is supported on PTX10008 running Junos OS Evolved Release 19.4R1-S1 and later. See Table 21 for the required hardware components for JNP10008-SF3 fabrics.

Network Ports

The QSFP56-DD ports support:

• 400GbE transceivers (QSFP56-DD)

• 400GbE active optic cables (QSFP56-DD AOCs)

• 4 x 100GbE transceivers (QSFP56-DD)

• 2 x 100GbE transceivers (QSFP28-DD)

• 100GbE transceivers (QSFP28)

• 100GbE AOCs (QSFP28)

• 40GbE transceivers (QSFP+)

• 40-Gigabit Ethernet to 10-Gigabit QSFP-to-SFP adapter (QSA) (Junos OS Release 20.2R1 and later)

Channelization

All 36 ports of the PTX10K-LC1201-36CD line card default to 400 Gigabit Ethernet. You can either set all the ports to a specific speed and channelization or you can channelize each port individually. The CLI syntax to channelize a port on the PTX10K-LC1201-36CD is release dependent.

For software releases from Junos OS Evolved 19.4R1-S1 up to Junos OS Evolved 20.1R2:

• Use the pic-mode and speed options on the Junos OS Evolved operational set chassis command:

  user@host>set chassis fpc 0-7 pic 0 pic-mode speed 400g|200g|100g|50g|40g|25g|10g

  In this example, fpc represents the line card slots from 0 to 7. There is a single PIC in the PTX10K-LC1201-36CD; it is always numbered zero. The pic-mode option indicates you are configuring all of ports on the PIC and not an individual port. With the speed options, you can configure 100-Gbps or 40-Gbps speed on all 36 ports, or you can configure four 10-Gbps channels on each of the 36 ports.

  For example, to set 100-Gbps speed on all ports in slot 2:

  user@host> set chassis fpc 2 pic 0 pic-mode speed 100g

  To individually configure a port, you need to specify both the speed and number of subports (channels).

  user@host> set chassis fpc 0-7 pic 0 port 0-35 speed 400g|200g|100g|50g|40g|25g|10g number-of-subports 1-8

  For example, to channelize port 15 in slot 0 to 4 downstream 100-Gigabit Ethernet interfaces:

  user@host> set chassis fpc 0 pic 0 port 15 speed 100g number-of-subports 4

  The resulting interfaces would be:
  Note

  If you do not specify the number-of-subports when configuring an individual port, the system will default to a value of 1. The same example, without the number-of-subports option, would then result in one downstream 100-Gigabit Ethernet interface.

For software releases from Junos OS Evolved 20.1R2 and later, the speed and number-of-subports options are now found in the interfaces hierarchy. For example, to channelize port 15 in slot 0 to 4 downstream 100-Gigabit Ethernet interfaces:

After saving and committing the changes, the resulting interfaces would be:

Network LEDs

Each network port has a single tricolored LED that indicates link activity and status. The red, amber, or green LED has different interpretations depending on whether the port is channelized, not channelized, or whether the beacon is activated (see Table 22). If the beacon feature is activated on the port, the port blinks.

Line Card Status LEDs

The line card has a power (PWR) LED and a status (STS) LED (see Table 23).

All these components require the Junos OS Evolved operating system. See also: Calculate Power Requirements for a PTX10008.

Network Ports and Channelization

On the PTX10K-LC1202-36MR line card, the ports 4, 10, 24, and 30 are the 400GbE (QSFP56-DD) ports, while the rest are 100GbE (QSFP28) ports. Each QSFP56-DD port runs at a default speed of 400 Gbps, while each of the QSFP28 ports supports a default speed of 100 Gbps.

Figure 16 shows the 400GbE ports highlighted.

Figure 16: PTX10K-LC1202-36MR - Network Ports

By using breakout cables, you can channelize the PTX10K-LC1202-36MR ports as described below.

• 4x10GbE transceivers (QSFP+)

You can configure port speeds at the interface level using the CLI command set interfaces interface-name number-of-sub-ports number-of-sub-ports.

Bandwidth Support Based on the Router Configuration

Table 25 explains the bandwidth supported by a PTX10K-LC1202-36MR line card based on the PTX10008 router configuration.

Network LEDs

Each network port has a single tricolored LED that indicates link activity and status. The red, amber, or green LED has different interpretations depending on whether the port is channelized or not channelized, or whether the beacon feature is activated (see Table 26.) If the beacon feature is activated on the port, the port blinks.

Line-Card Status LEDs

The line card has a power (PWR) LED and a status (STS) LED (see Table 27).

QFX10000-60S-6Q Line Card

• Hardware Features

• Port Groups

• Channelization of 40-Gigabit Ethernet Ports

• Using Copper and Fiber SFP Transceivers

• SFP+ Status and Activity LEDs

• QSFP+ and QSFP28 Status and Activity LEDs

Hardware Features

The QFX10000-60S-6Q line card consists of 60 small form-factor pluggable plus (SFP+) ports that support 10-Gbps or 1-Gbps port speed, 2 dual-speed QSFP28 ports that support either 40-Gbps or 100-Gbps port speed, and 4 QSFP+ ports that support 40-Gbps port speed. All of the QSFP and SFP+ ports are configured to 10-Gbps by default. The QSFP28 ports are configured as 40-Gbps speed ports by default, but port 60 and port 64 are dual-speed ports and can be configured to support either 10-Gigabit Ethernet or 40-Gigabit Ethernet optical transceivers. Ports 60 and 64 can also be configured to support 100-Gigabit Ethernet optical transceivers. See the Hardware Compatibility Tool for details of supported optical transceivers. See Figure 17.

The QFX10000-60S-6Q line card is supported on Junos OS Release 19.1R1 and later.

Figure 17: QFX10000-60S-6Q Port Panel

1 — Power LED (PWR), status LED (STS), and offline/online (OFF) button	3 — QSFP28 ports, QSFP+ ports, and port groups
2 — SFP+ ports

Each QSFP28 port (60 and 64) controls a port group and can be configured as a:

• 100-Gigabit Ethernet port by using QSFP28 optical transceivers. The interface speeds are configured by port group. When a QSFP28 transceiver is inserted into one of the QSFP28 ports marked with a fine black line above the port (60 or 64) and the port is configured for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 port is enabled for 100-Gigabit Ethernet. When port 60 is configured for 100-Gbps, ports 61 and 62 are disabled; when port 64 is configured for 100-Gbps, ports 63 and 65 are disabled.

• 40-Gigabit Ethernet port by using QSFP+ optical transceivers. The default speed is 10 Gbps.

• 10-Gigabit Ethernet port by using breakout cables and attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into four independent 10-Gigabit Ethernet ports (or channels). Use the set chassis fpc fpc-slot-numbers pic pic-slot-number port port-number speed speed command to change the port speed.

Each QSFP+ port (61, 62, 63, and 65) is part of a port group and is controlled by one of the associated QSFP28 ports (60 or 64). If a QSFP28 port operates at 40-Gbps speed, then each of the QSFP+ ports can be configured as a:

• 40-Gigabit Ethernet port by using QSFP+ optical transceivers. The default speed is 10 Gbps.

• 10-Gigabit Ethernet port by using breakout cables with attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into four independent 10-Gigabit Ethernet ports (or channels). Use the set chassis fpc fpc-slot-number pic pic-slot-number port port-number speed speed command to change the port speed.

Each SFP+ port (0 through 59) can be configured as a 10-Gigabit Ethernet port by using SFP+ optical transceivers. The default speed is 10 Gbps.

You can install copper SFP transceivers only on ports located in the lower two SFP+ port rows (at the bottom). Copper SFP transceivers are only supported on the bottom two SFP+ rows. The copper SFP transceivers (1000BASE-T) are limited to these rows because they are physically larger than optical SFP transceivers (1000BASE-X). Stacking copper SFP transceivers in all three rows causes internal damage to the line card. Optical SFP transceivers can be stacked and used in all SFP+ ports, 0 through 59.

Any of the 66 ports 0 through 65 can be configured as either uplink or access ports. The ports are enabled by default, and the default configuration adds the ports to the default VLAN.

Port Groups

The six combination ports of QSFP28 and QSFP+ can operate either as six independent 40-Gigabit Ethernet ports or as two port groups. The first port group is controlled by QSFP28 port 60 and administratively bundled with QSFP+ ports 61 and 62. The second port group is controlled by QSFP28 port 64 and administratively bundled with QSFP+ ports 63 and 65. To enable the port group, insert a 100-Gigabit Ethernet transceiver into the QSFP28 port and configure the port as a 100-Gbps port. Junos OS enables the QSFP28 port at 100-Gbps speed and disables the two QSFP+ ports bundled in the port group. Figure 18 shows the location of QSFP28 ports and port groups for the QFX10000-60S-6Q. Table 28 shows the available combinations for the ports.

Figure 18: QFX10000-60S-6Q Port Groups

Channelization of 40-Gigabit Ethernet Ports

Channelization from a 40-Gigabit Ethernet port into four independent 10-Gigabit Ethernet ports is supported on the QSFP28 and QSFP+ ports. Channelization to 50-Gbps or 25-Gbps speed is not supported on the 100-Gigabit Ethernet QSFP28 port. All ports in the port group are channelized when port 60 or port 64 is channelized. Ports cannot be channelized individually.

To channelize a 40-Gbps port to four independent 10-Gbps ports (or channels), use the set chassis fpc fpc-slot-number pic pic-slot-number port port-number channel-speed speed command. For example, to channelize ports 60 through 62 for a line card in slot 6:

Review your configuration and issue the commit command.

If you want to return the port to the default, delete the speed statement from the configuration at the [chassis fpc 6 pic 1 port port-number] hierarchy level and commit the configuration. The network port is reset to the default 40-Gigabit Ethernet interface.

Using Copper and Fiber SFP Transceivers

When you configure the 10-Gigabit Ethernet ports 0 to 59 as 1-Gigabit Ethernet ports, you can use optical fiber SFP transceivers in any of the ports. However, copper SFP transceivers are restricted to the lower two rows. See Figure 19.

Figure 19: Supported Placement for Copper and Fiber SFP+ Transceivers

Because 1-Gbps copper SFP transceivers are physically larger than optical SFP transceivers, there is insufficient room for three copper SFP transceivers to be stacked. Use the top row only for optical SFP transceivers. You can stack copper transceivers in the bottom two rows. Ports are arranged belly-to-belly. Stacking three SFP transceivers in a column can damage the line card. For the recommended configuration, see Figure 20.

SFP+ Status and Activity LEDs

All status and activity LEDs for the SFP+ ports are located between the second and third rows of SFP+. The up arrow, circle, and down arrow indicate the row of the status. A bicolor LED indicates the status and activity. See Figure 21 and Table 29.

• An up arrow indicates the first row.

• A circle indicates the second row.

• A down arrow indicates the third row.

QSFP+ and QSFP28 Status and Activity LEDs

All QSFP+ and QSFP28 ports have an up or down indicator for each port and four bicolored LEDs that show port status and link activity based on whether or not the port is configured for channelization. See Table 30.

PTX10008 Line-Card LEDs

All PTX10008 line cards have two bicolored LEDs. The PTX10K-LC1201-36CD LEDs are green and red, while the other line-card LEDs are green and amber. See Figure 23.

Figure 23: Line–Card LEDs

Table 31 describes the functions of the line-card LEDs other than PTX10K-LC1201-36CD. See Table 32 for PTX10K-LC1201-36CD behavior.

Taking a Line Card Online or Offline

The offline/online (OFF) button is recessed below the faceplate directly below the status (STS) LED. You can take any of the PTX10008 line cards online or offline using either of these two methods:

• Press the OFF button with a non-conductive pin tool, such as a toothpick, until the STS LED turns off after about 5 seconds.

• Issue the CLI command:
