PTX1000 Port Panel

 

PTX1000 Port Panel

The PTX1000 supports 10-Gbps, 40-Gbps, and 100-Gbps port speeds. Figure 1 shows the PTX1000 port panel and management panel.

Each of the 72 network ports on the port panel supports quad small form-factor pluggable plus (QSFP+) transceivers. By default, the network ports operate as channelized 4 x 10-Gigabit Ethernet interfaces—using QSFP+ to SFP+ fiber breakout cables—for a maximum of 288 10-Gigabit Ethernet ports. You can configure each of the 72 ports as a 40-Gigabit Ethernet interface, in groups of three ports—when you configure the first port in a port group to operate at 40 Gbps, that port and the next two ports operate at 40 Gbps. You can also configure 24 of the 72 network ports as 100-Gigabit Ethernet interfaces. The 24 network ports that can be configured as 100-Gigabit Ethernet interfaces support QSFP28 transceivers.

Note

Network ports that can be configured as 100-Gigabit Ethernet interfaces are marked with a fine black line underneath the transceiver socket. When the port is configured as a 100-Gigabit Ethernet interface, the two adjacent ports are disabled. For example, port 1 supports 100-Gbps port speed. When you configure the port as a 100-Gigabit Ethernet interface, port 0 and port 2 are disabled.

Note

Port speeds are configured using the set chassis fpc 0 pic 0 port port-number speed speed command. You configure ports to operate at 40 Gbps by using the 40g speed option. You configure ports to operate at 100 Gbps by using the 100g speed option. If you configure a port to operate at 40 Gbps or 100 Gbps, and you want to return the port to the default configuration, delete the speed statement from the configuration at the [chassis fpc 0 pic 0 port port-number] hierarchy level and commit the configuration. The network port is reset to the default 4 x 10-Gigabit Ethernet interface. Table 1 shows the available combinations for the network ports on the PTX1000.

Example: Using Network Ports as 40-Gigabit Ethernet Interfaces

All network ports on the PTX1000 can be configured as 40-Gigabit Ethernet interfaces. You must configure 40-Gigabit Ethernet interfaces in groups of three network ports. When the port speed is configured as 40 Gbps on the first port in a port group, all three ports in the port group operate at 40 Gbps. For example, if you configure port 0 as a 40-Gigabit Ethernet inteface, ports 1 and 2 are also 40-Gigabit Ethernet interfaces (see Figure 2). Table 1 provides the complete list of port groups that can be configured as 40-Gigabit Ethernet interfaces.

When port 0 is configured to operate at 40 Gbps, ports 1 and 2 also operate at 40 Gbps (in blue).
  2
When port 3 is configured to operate at 40 Gbps, ports 4 and 5 also operate at 40 Gbps (in green).
Note

40-Gigabit Ethernet interfaces are configured using the set chassis fpc 0 pic 0 port port-number speed speed command. For example, to configure the first set of three network ports as 40-Gigabit Ethernet interfaces, use the set chassis fpc 0 pic 0 port 0 speed 40g command. After you commit this configuration, each of the three ports (0, 1, and 2) operate at 40 Gbps.

Example: Using Network Ports as 100-Gigabit Ethernet Interfaces

Starting with port 1, every second and sixth port in each group of six network ports can be configured as 100-Gigabit Ethernet interfaces. Figure 3 shows the 100-Gigabit Ethernet-capable ports in a group of six network ports, designated by a fine black line underneath the port.

When the port speed is configured as 100 Gbps in the CLI, Junos OS disables two associated network ports from that port group. For example, if you configure port 1 as a 100-Gigabit Ethernet interface, ports 0 and 2 are disabled (see Figure 4). Table 1 provides the complete list of ports that can be configured to operate as 100-Gigabit Ethernet interfaces, and the corresponding ports that are disabled.

Configuring port 1 as a 100-Gigabit Ethernet interface causes ports 0 and 2 to be disabled (in blue).
  2
Configuring port 5 as a 100-Gigabit Ethernet interface causes ports 3 and 4 to be disabled (in green).
Note

100-Gigabit Ethernet interfaces are configured using the set chassis fpc 0 pic 0 port port-number speed speed command. For example, to configure port 1—the first 100-Gigabit Ethernet-capable port—use the set chassis fpc 0 pic 0 port 1 speed 100g command. After you commit this configuration, port 1 operates at 100 Gbps, while ports 0 and 2 are disabled.

PTX1000 Network Port LEDs

Each PTX1000 network port uses a single bicolored LED to indicate link status and activity. The triangular LEDs are located between the top row and bottom row of ports. The LEDs are shaped so that each LED points to the port with which it is associated. Figure 5 shows the location of the LEDs.

Note

The same bicolored LED also indicates status when the port is configured to operate as four 10-Gigabit Ethernet interfaces.

Table 2 describes the network port LEDs.
