PTX10004 Line Card Components and Descriptions

Overview

The line card houses five Juniper Networks' custom ASICs, and each ASIC houses two Packet Forwarding Engines. One packet forwarding engine in the fifth ASIC is not used.

You can install the PTX10K-LC1201-36CD line card in the PTX10004, PTX10008, and PTX10016 chassis horizontally at the front of the chassis.

PTX10004 routers running Junos OS Evolved Release 20.3R1 with Junos Continuity and later support the PTX10K-LC1201-36CD line card. PTX10008 routers running Junos OS Evolved Release 19.4R1-S1 and later support the PTX10K-LC1201-36CD line card. PTX10016 routers running Junos OS Evolved Release 21.2R2 and later support the PTX10K-LC1201-36CD line card. The PTX10K-LC1201-36CD line card interoperates with the PTX10K-LC1202-36MR line card on a PTX10004, PTX10008, or PTX10016 router. The PTX10K-LC1201-36CD line card interoperates with the PTX10K-LC1301-36DD line card in PTX10004 and PTX10008 routers.

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+)

• 40GbE to 10GbE QSA (Junos OS Release 20.2R1 and later)

Channelization

All 36 ports of the PTX10K-LC1201-36CD line card default to 400GbE. You can either set all the ports to a specific speed and channelization or 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 Release 19.4R1-S1 to Junos OS Evolved Release 20.1R2:

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

In this example, fpc slot represents the line card slots. There is a single PIC in the PTX10K-LC1201-36CD; it is always numbered zero. The pic-mode option indicates that 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:

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

For example, to channelize port 15 in slot 0 to 4 downstream 100GbE interfaces:

The resulting interfaces would be:

Note:

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

For software releases Junos OS Evolved Release 20.1R2 and later, the speed and number-of-subports options are in the interfaces hierarchy. For example, to channelize port 15 in slot 0 to four downstream 100GbE interfaces:

After you save and commit the changes, each of the following resulting interfaces would be:

Bandwidth Support

Network LEDs

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

Overview

The PTX10K-LC1202-36MR (model number: JNP10K-LC1202) is a 36-port line card that provides a line rate throughput of 4.8 Tbps. The line card has 32 QSFP28 ports, each capable of supporting a maximum speed of 100 Gbps, and four QSFP56-DD ports, each capable of supporting a maximum speed of 400 Gbps (see Figure 2).

In a pure 100-Gbps port speed configuration, the line card supports a throughput of 3.6 Tbps (each of the 36 ports runs at 100-Gbps speed).

In a mixed-speed configuration of 100 Gbps and 400 Gbps, the line card supports a line rate throughput of 4.8 Tbps (thirty-two 100-Gbps ports and four 400-Gbps ports).

The line card houses two Juniper Networks' custom ASICs, and each ASIC houses two Packet Forwarding Engines. The line card supports a maximum throughput of 1.2 Tbps per Packet Forwarding Engine.

You can install the PTX10K-LC1202-36MR line card in the PTX10004, PTX10008, and PTX10016 chassis horizontally at the front of the chassis.

The acoustics noise for the line card is 85 dBA.

Network Ports and Channelization

On the PTX10K-LC1202-36MR line card, the ports 4, 10, 24, and 30 are 400GbE (QSFP56-DD) ports, whereas the rest are 100GbE (QSFP28) ports.

Figure 3 shows the 400GbE ports highlighted.

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

The QSFP56-DD ports (ports 4, 10, 24, and 30) on the line card support the following transceivers:

• 1x400GbE transceivers (QSFP56-DD)

• 4x100GbE transceivers (QSFP56-DD)

• 2x100GbE transceivers (QSFP28-DD)

• 1x100GbE transceivers (QSFP28)

• 2x50GbE transceivers (QSFP28)

• 1x40GbE transceivers (QSFP+)

• 8x25GbE transceivers (QSFP28-DD)

• 4x25GbE transceivers (QSFP28)

• 4x10GbE transceivers (QSFP+)

• 1x10GbE transceivers (SFP+)

• 40GbE to 10GbE QSA, starting in Junos OS Evolved Release 20.4R1 and later.

The QSFP28 ports 0, 2, 5 through 9, 11 through 18, 20, 22, 23, 25 through 29, and 31 through 35 on the line card support the following transceivers:

• 1x100GbE transceivers (QSFP28)

• 2x50GbE transceivers (QSFP+)

• 1x40GbE transceivers (QSFP+)

• 4x25GbE transceivers (QSFP28)

• 4x10GbE transceivers (QSFP+)

• 1x10GbE transceivers (QSFP+)

The QSFP28 ports 1, 3, 19, and 21 on the line card support the the 1x100GbE QSFP28 transceivers.

Note:

The ports 1, 3, 19, and 21 must be configured as unused if the preceding ports (0, 2, 18, and 20) are not in 100-Gbps mode. This means, of the 36 ports on the PTX10K-LC1202-36MR line card, only 32 ports are available to be configured as 4x25GbE and 4x10GbE ports.

See the Port Checker tool to see the supported port speeds.

You can configure port speeds at the interface level using the set interfaces <interface-name> speed <speed> command.

Overview

The PTX10K-LC1301-36DD line card (model number: JNP10K-LC1301) is a 36-port line card that offers a line rate throughput of 28.8 Tbps. The 36 high-density 800-Gigabit Ethernet (800GbE) QSFP-DD ports support speeds of up to 800 Gbps. The line card houses two Juniper Networks' custom Express 5 ASICs, and each ASIC comprises of two Packet Forwarding Engines.

The ports support QSFP+, QSFP28, QSFP56-DD, and 400G-ZR transceivers. When the line card is operating in the normal power mode, you can install up to 36 800-Gbps or 2x400 Gbps transceivers.

You can configure the line card to operate in the low-power mode by using the set chassis fpc <fpc-slot> low-power-mode command. When the line card is operating in the low-power mode, you can install up to 36 400-Gbps transceivers.

You can also use breakout cables, active optical cables (AOCs), and the number-of-sub-ports (interface) configuration to channelize the ports to operate at the following speeds:

• 1x800 Gbps

• 2x400 Gbps

• 1x400 Gbps

• 8x100 Gbps

• 7x100 Gbps

• 6x100 Gbps

• 5x100 Gbps

• 4x100 Gbps

• 3x100 Gbps

• 2x100 Gbps

• 1x100 Gbps

• 8x50 Gbps

• 4x50 Gbps

• 2x50 Gbps

• 1x40 Gbps

• 8x25 Gbps

• 4x25 Gbps

• 4x10 Gbps

• 1x10 Gbps

The links on the ports come up at 800-Gbps speed by default. You can change the port speed by using the set interfaces <interface-name> speed <speed> command.

Juniper Networks Port Checker (https://apps.juniper.net/port-checker/) provides a visual representation of various Juniper network devices, and assists to configure and validate different port combinations.

The software features for the line card are documented in Release Notes: Junos OS Evolved Release 24.4R1.

The maximum throughput that the line card offers in PTX10004 routers with JNP10004-SF3 installed and in PTX10008 routers with JNP10008-SF3 installed is 12.8 Tbps. The total throughput that a port group of nine ports (0 through 8, 9 through 17, 18 through 26, and 27 through 35) can offer is 3.2 Tbps. If a port group is oversubscribed, traffic is dropped at ingress, overriding the Class of Service (CoS) profiles.
