Use the slot/port [.subinterface] format for Fast Ethernet interfaces on ERX7xx models,
ERX14xx models, and the ERX310 router . Use the slot/adapter/port format for the SRP
IOA on the E120 or E320 routers; the port on the SRP IOA is always identified by 0.
Example 1—Selects a Fast Ethernet interface on ERX7xx models, ERX14xx models, or
the ERX310 router
host1(config)#interface fastEthernet 1/0
Example 2—Selects the Fast Ethernet management port on an E320 router
host1(config)#interface fastEthernet 6/0/0
Use the no version to remove IP from an interface or subinterface. You must issue the
no version from the highest level down; you cannot remove an interface or subinterface
if the one above it still exists.
See interface fastEthernet.
Use to select a Gigabit Ethernet interface.
NOTE: On the GE I/O module, you can configure only the primary port, 0.
The router automatically uses the redundant port, 0R, if the primary port
fails.
On the GE-2 SFP I/O module, you can configure only the primary ports, 0
and 1. The router automatically uses the corresponding redundant port, 0R
or 1R, if the primary port fails.
On the OC3-2 GE APS I/O module, you can configure only port 2. Ports 0
and 1 are reserved for OC3/STM1 ATM interfaces. This I/O module does
not support redundant ports in the current release.
On the ES2-S1 GE-4 IOA, you can configure all four ports.
On the ES2-S1 GE-8 IOA, you can configure all eight ports.
Use the slot/port [.subinterface] format for Gigabit Ethernet interfaces on ERX7xx
models, ERX14xx models, or the ERX310 router; use the slot/adapter/port format for
Gigabit Ethernet interfaces on the E120 and E320 routers.
Example 1—Selects a Gigabit Ethernet interface on ERX7xx models, ERX14xx models,
and the ERX310 router
host1(config)#interface gigabitEthernet 1/0
host1(config)#interface gigabitEthernet 2/1
Example 2—Selects a Gigabit Ethernet interface on the E320 router
host1(config)#interface gigabitEthernet 4/0/1
