Figure 6: 100-Gigabit Ethernet Ports Indicated by a 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 7 on page 26). Table 6 on page 27 provides the complete list of ports that
can be configured to operate as 100-Gigabit Ethernet interfaces, and the corresponding ports that are
disabled.
Figure 7: 100-Gigabit Ethernet Interface Configuration Disables Two Associated Ports
2—1— Configuring port 5 as a 100-Gigabit Ethernet interface
causes ports 3 and 4 to be disabled (in green).
Configuring port 1 as a 100-Gigabit Ethernet interface
causes ports 0 and 2 to be disabled (in blue).
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.
