PTX10004 Line Card Components and Descriptions

Overview

The PTX10K-LC1201-36CD line card houses Packet Forwarding Engine based on Juniper Networks' custom ASICs to deliver a 400GbE solution for data centers.

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 (see Table 1).

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 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 Release 19.4R1-S1 to Junos OS Evolved Release 20.1R2:

1. Use the pic-mode and speed options on the Junos OS Evolved operational 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 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 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 100GbE interface.

Note:

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 4 downstream 100GbE interfaces:

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

Bandwidth Support

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

Number of Switch Fabric Cards Used	Bandwidth per Slot Without Fabric Redundancy
6	14.4 Tbps
5	12 Tbps
4	9.6 Tbps
3	7.2 Tbps

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 3). If the beacon feature is activated on the port, the port blinks.

Table 3: PTX10K-LC1201-36CD Network LEDs

Port Status	Normal State	Description
Nonchannelized	Unlit, off	A transceiver is not present in the port or the link is down because of a loss of signal.
	Green, on steadily	A link is established.
	Amber, on steadily	The link is down because of a remote error or because the port was disabled through the CLI.
	Red, on steadily	The link is down because of a hardware failure or a local error.
Channelized	Unlit, off	All channels are down because of loss of signal.
	Green, on steadily	A link is established and all channels are up.
	Amber, on steadily	Applies to all other cases.
	Red, on steadily	The port has a hardware failure.

Overview

The PTX10K-LC1202-36MR is a 36-port line card that provides a line rate throughput of 4.8 Tbps. The line card has thirty-two 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 is designed to operate using the newer Routing Engines, the JNP10004-SF3 switch fabric, the JNP10008-SF3 switch fabric, or the JNP10016-SF3 switch fabric; the JNP10K-PWR-AC2 or JNP10K-PWR-DC2 power supply; the JNP10004-FAN2, the JNP10008-FAN2, or JNP10016-FAN fan tray; and the JNP10004-FTC2, the JNP10008-FTC2, or the JNP10016-FTC2 fan tray controller. These components require Junos OS Evolved.

The PTX10K-LC1202-36MR line card houses Packet Forwarding Engines based on Juniper Networks' custom ASICs. The line card has two custom ASICs, each hosting 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.

Network Ports and Channelization

On the PTX10K-LC1202-36MR line card, the ports 4, 10, 24, and 30 are 400GbE (QSFP56-DD) ports, while 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)

• 8x25GbE transceivers (QSFP28-DD)

• 1x100GbE transceivers (QSFP28)

• 4x25GbE transceivers (QSFP28)

• 4x10GbE transceivers (QSFP+)

• 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)

• 4x25GbE transceivers (QSFP28)

• 4x10GbE 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 4x25 Gbps and 4x10 Gbps ports.

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

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 .
