PTX10003 Port Panel

 

PTX10003-160C Port Panel

Operating in a fixed core router configuration, the PTX10003-160C features flexible interface configuration options with universal multi-rate double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The port panel has 80 optical interfaces which support data rates of 10 Gbps, 25 Gbps, 40 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps. Each of the 16 Juniper Networks 1 Tbps ExpressPlus ASICs in the PTX10003-160C connect to a group of five QSFP-DD ports. You can configure different data rates for each port group as long as the total throughput for the group does not exceed 1 Tbps. For more details, see Understanding QSFP-DD Interfaces and Configurations.

As illustrated in Figure 1, the interfaces for the PTX10003-160C are divided into logical FPCs, logical PICs, and physical optical ports as follows:

  • FPCs: The PTX10003-160C has four FPCs, numbered 0, 1, 2, and 3 from the bottom up in the chassis.

  • PICs: Each FPC has two logical PICs, numbered 0 and 1 from left to right.

  • Ports:: Each PIC controls 10 QSFP-DD optical interfaces, numbered 0 through 9 from left to right.

  • The 10 QSFP-DD optical interfaces are divided into two groups of five ports.

  • Each port group is controlled by two PFEs.

PTX10003-80C Port Panel

Operating in a fixed core router configuration, the PTX10003-80C features flexible interface configuration options with universal multi-rate double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The port panel has 40 optical interfaces which support data rates of 10 Gbps, 25 Gbps, 40 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps. Each of the eight Juniper Networks 1 Tbps ExpressPlus ASICs in the PTX10003-80C connect to a group of five QSFP-DD ports. You can configure different data rates for each port group as long as the total throughput for the group does not exceed 1 Tbps. See Understanding QSFP-DD Interfaces and Configurations for more details.

  • Ports:: Each PIC controls 10 QSFP-DD optical interfaces, numbered 0 through 9 from left to right.

  • The 10 QSFP-DD optical interfaces are divided into two groups of five ports.

  • Each port group is controlled by two Packet Forwarding Engines (PFE).

Understanding QSFP-DD Interfaces and Configurations

Each Juniper Networks 1 Tbps ExpressPlus ASIC contains two logically independent PFEs which can provide 400 Gbps throughput. Each QSFP-DD port group is controlled by two PFEs with the middle QSFP-DD interface (port 2 and port 7) being shared by the PFEs.

Any port can be used as a 100-Gigabit Ethernet interface, 40-Gigabit Ethernet interface, or 10-Gigabit Ethernet interface. You choose the speed by plugging in the appropriate optical transceiver. You can also channelize the 100 Gbps and 200 Gbps ports to create multiple independent 25 Gbps interfaces. You can channelize the 40 Gbps ports to create multiple independent 10 Gbps ports. See Channelizing Interfaces on PTX10003 Routers for more details.

Given the design of the Juniper Networks ExpressPlus ASIC and chassis level thermal considerations, there are certain limitations for some QSFP-DD interfaces and configurations. Each QSFP-DD port group can be configured to achieve the maximum 1 Tbps throughput with the following limitations:

  • Only the interfaces at the outer edge of each QSFP-DD group can be configured for 1x400 Gbps (using QSFP56-DD optics).

  • The middle QSFP-DD port that is shared across two PFE’s (port 2 and port 7) cannot support a data rate of 1x200 Gbps. These ports can only support 2x100 Gbps (QSFP28-DD).

  • The highest QSFP-DD data rate that can be used across all QSFP-DD groups is 200 Gbps (2x100 Gbps). This provides 16 Tbps throughput for the PTX10003-160C, and 8 Tbps throughput for the PTX10003-80C.

  • Aside from running all interfaces with 2x100 Gbps optics, there are other ways to attain the maximum system throughput. The 400 Gbps optics can be used in combination with 100 Gbps optics and 200 Gbps optics as shown in the following examples.

Examples of PTX10003 QSFP-DD Configurations

By default, all PTX10003 QSFP-DD interfaces are configured for a data rate of 2x100 Gbps. You can change the port configuration to achieve different throughput using the following Junos OS Evolved command:

set chassis fpc slot-number pic pic-number port port-number number-of-subports [1 | 2 | 4  |8] speed [10G | 25G | 40G | 100G | 200G |400G] command.

For example, to configure the second port in the first port group as a 4x10 Gbps interface, use the set chassis fpc 0 pic 0 port 1 number-of-subports 4 speed 10g command. After you commit this configuration, the second port in PIC 0 will operate at 4x10 Gbps.

Note

When a port speed and sub-port-number are configured, the configured values override the default port speed for the transceiver. If you try to configure a port speed that is not supported by the transceiver, the port will be disabled. If there isn’t a port speed configured on a valid optical port, the PTX10003 uses a default port speed of 2x100 Gbps. Also, if number-of-subports is not configured, a 1x 40G | 100G |200G |400G] data rate is assumed. A 1x10G sub-port is not supported.

Example: Using Network Ports as 10 Gbps or 40 Gbps Ethernet Interfaces

With QSFP+ transceivers, you can configure 10 Gbps or 40 Gbps interfaces on any port. To attain the maximum 1 Tbps throughput for a port group, you can configure the 10 Gbps and 40 Gbps ports with combinations of 1x100 Gbps, 2x100 Gbps, and 400 Gbps, data rates. Refer to Table 3.

Note

1x10 Gbps and 2x10 Gbps are not supported.

Note

Only the ports at the outer edge of each group can be configured for 1x400 Gbps (using QSFP56-DD transceivers).

Note

The center port in each port group (port 2 and port 7) cannot support 1x200 Gbps. To configure a 200 Gbps data rate for those ports, you’ll need to configure them as 2x100 Gbps.

  • Only the ports at the outer edge of each group can be configured for 1x400 Gbps (using QSFP56-DD transceivers).

  • When ports 0, 4, 5, 9 are configured as 1x400 Gbps, the center ports 2 and 7 must be blank.

  • When configuring a port for 1x200 Gbps, port 1, 3, 6 and 8 must be blank or configured as 1x100 Gbps.

PTX10003 Port LEDs

Each PTX10003 port uses a single bi-colored LED to indicate link status and activity. See Table 7 for how to interpret the port LEDs.

Note

After you insert an optical transceiver, the LINK UP LED flashes red and green during the first 60 seconds. This means the link is unstable. It may take up to 60 seconds for the LED to stop flashing.

Channelizing Interfaces on PTX10003 Routers with Junos OS Evolved

PTX10003 Packet Transport Routers feature flexible interface configuration options with universal multi-rate double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The PTX10003-80C port panel has 40 physical ports and the PTX10003-160C port panel has 80 physical ports. The physical ports are in groups of five QSFP-DD ports. You can configure different data rates for each port group as long as the total throughput for the group does not exceed 1 Tbps. Any port can be used as a 100-Gigabit Ethernet interface, 40-Gigabit Ethernet interface, or 10-Gigabit Ethernet interface. You choose the speed by plugging in the appropriate transceiver.

Note

The center port in each port group (port 2 and port 7) cannot support 1x200 Gbps. To configure a 200 Gbps data rate for those ports, you’ll need to configure them as 2x100 Gbps. For more details, see Understanding QSFP-DD Interfaces and Configurations.

You can channelize the Gigabit Ethernet interfaces on PTX10003 routers to create multiple independent Gigabit Ethernet interfaces and then use breakout cables to connect the channelized ports to other servers, storage devices, and routers. Here’s the allowable channelization configurations for the optical transceivers supported by the PTX10003:

By default, all PTX10003 QSFP-DD interfaces are configured for a data rate of 2x100 Gbps. The interface names appear in the et-fpc/pic/port:channel format.

The port speed can be configured at the PIC-level. To view the port speed capability of a logical PIC, issue the show chassis pic fpc-slot slot-number pic-slot slot-number command.
