To view which interfaces are enabled for Layer 3 data transmission, use the show ip interfaces
brief command in EXEC Privilege mode. In the following example, TengigabitEthernet interface 1/5 is in
Layer 3 mode because an IP address has been assigned to it and the interface’s status is operationally up.

TengigabitEthernet 1/0 unassigned NO Manual administratively down down
TengigabitEthernet 1/1 unassigned NO Manual administratively down down
TengigabitEthernet 1/2 unassigned YES Manual up up
TengigabitEthernet 1/3 unassigned YES Manual up up
TengigabitEthernet 1/4 unassigned YES Manual up up

TengigabitEthernet 1/6 unassigned NO Manual administratively down down
TengigabitEthernet 1/7 unassigned NO Manual administratively down down
TengigabitEthernet 1/8 unassigned NO Manual administratively down down
To view only configured interfaces, use the show interfaces configured command in the EXEC
Privilege mode. In the previous example, TengigabitEthernet interface 1/5 is in Layer 3 mode because an
IP address has been assigned to it and the interface’s status is operationally up.
To determine which physical interfaces are available, use the show running-config command in EXEC
mode. This command displays all physical interfaces available on the line cards.
