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.

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:

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

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:

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 fpc-number pic 0 port port-number speed 400g|200g|100g|50g|40g|25g|10g number-of-subports subport-number

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

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

The resulting interfaces would be:

et-0/0/15:0
et-0/0/15:1
et-0/0/15:2
et-0/0/15:3

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:

[edit-interfaces]
user@host> et-0/0/15
 {speed 100g;
number-of-subports 4;
}
et-0/0/15:0 {unit 0}
et-0/0/15:1 {unit 0}
et-0/0/15:2 {unit 0}
et-0/0/15:3 {unit 0}

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

et-0/0/15:0
et-0/0/15:1
et-0/0/15:2
et-0/0/15:3

Bandwidth Support

Table 2 lists the bandwidth supported by each PTX10K-LC1201-36CD line card.

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.

Line Card Status LEDs

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

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.

Components Required for PTX10K-LC1202-36MR

PTX10004 routers running Junos OS Evolved Release 20.3R1 with Junos Continuity and later support the PTX10K-LC1202-36MR line card. PTX10008 routers running Junos OS Evolved Release 20.3R1 and later (with Junos Continuity) support the PTX10K-LC1202-36MR line card.

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.

• 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)

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

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.
