PTX10003 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, 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.

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, 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.

As illustrated in Figure 2, the interfaces for the PTX10003-80C are divided into logical FPCs, logical PICs, and physical optical ports as follows:

• FPCs: The PTX10003-80C has two FPCs, numbered 0 and 1 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 Packet Forwarding Engines (PFE).

Each Juniper Networks 1 Tbps ExpressPlus ASIC contains two logically independent PFEs which can provide 500 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 ports to create multiple independent 25 Gbps interfaces. You can channelize the 40 Gbps ports to create multiple independent 10 Gbps ports. See Channelization Configuration on PTX10003 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 QSFP-DD port in the middle (port 2 and port 7) is shared across two PFEs. These ports can 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.

Assuming the limitations described previously, Table 1 lists the allowable interface configurations for the PTX10003-160C.

Assuming the limitations described previously, Table 2 lists the allowable interface configurations for the PTX10003-80C.

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 | 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.

• Example: Using Network Ports as 1x400 Gbps Ethernet Interfaces
• Example: Using Network Ports as 4x100 Gbps Ethernet Interfaces

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:

Starting in Junos OS Evolved Release 19.3R1, you can use the Mellanox 10-Gbps pluggable adapter (model number: MAM1Q00A-QSA) to convert quad-lane-based ports to a single-lane-based SFP+ port. The QSA adapter has the QSFP+ form factor with a receptacle for the SFP+ module. Use the QSA adapter and the set chassis fpc slot-number pic pic-number port port-number number-of-subports 4 speed 10G command to convert a 40-Gbps port to a 10-Gbps port. You can plug a 10-Gbps SFP+ transceiver into the QSA adapter, which is then inserted into the QSFP or QSFP+ port of the PTX10003-80C or PTX10003-160C router.

Note:

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

Table 3: Using Network Ports as 10 Gbps or 40 Gbps Ethernet Interfaces

Data Rate	QSFP Transceiver	Allowable Port Numbers	Maximum Number of Ports (PTX10003-160C)	Maximum Number of Ports (PTX10003-80C)
4x10 Gbps	QSFP+	0-9	320	160
1x40 Gbps	QSFP+	0-9	80	40

Example: Using Network Ports as 100 Gbps Ethernet Interfaces

With QSFP28 and QSFP28-DD transceivers, you can configure a 2x100 Gbps data rate on any port. This is the default port configuration. To attain the maximum 1 Tbps throughput for a port group using 100 Gbps interfaces, you can configure combinations of 1x100 Gbps, 2x100 Gbps, and 4x100 Gbps data rates. Refer to Table 4.

Table 4: Using Network Ports as 100 Gbps Interfaces

Data Rate	QSFP Transceiver	Allowable Port Numbers	Maximum Number of Ports (PTX10003-160C)	Maximum Number of Ports (PTX10003-80C)
1x100 Gbps	QSFP28	0-9	80	40
2x100 Gbps	QSFP28-DD	0-9	160	80
4x100 Gbps	QSFP56-DD	0, 4, 5, 9	128	64

Example: Using Network Ports as 1x400 Gbps Ethernet Interfaces

With QSFP56-DD transceivers, you can configure a data rate of 1x400 Gbps on the two outer ports in a port group. To attain the maximum 1 Tbps throughput, you can configure combinations of two ports of 1x400 Gbps and two ports of 1x100 Gbps data rates in a port group with the following limitations:

• 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. You must configure the blank ports by using the set chassis fpc fpc-slot-number pic pic-slot-number port port-number unused command.

Data Rate	QSFP Transceiver	Allowable Port Numbers	Maximum Number of Ports (PTX10003-160C)	Maximum Number of Ports (PTX10003-80C)
1x400 Gbps	QSFP56-DD	0, 4, 5, 9	32	16
4x100 Gbps	QSFP56-DD	0, 4, 5, 9	128	64
2x100 Gbps	QSFP28-DD	0-9	160	80

Note:

Starting in Junos OS Evolved Release 19.3R1, we support 400 Gbps data rates.

Each PTX10003 port uses a single bi-colored LED to indicate link status and activity. See Table 6 for how to interpret the port LEDs.
