Figure 20-1.  show interfaces Command Example 
Use the show ip interfaces brief command in the EXEC Privilege mode to view which interfaces are 
enabled for Layer 3 data transmission. In Figure 20-2, GigabitEthernet interface 1/5 is in Layer 3 mode 
since an IP address has been assigned to it and the interface’s status is operationally up. 
Figure 20-2.  show ip interfaces brief Command Example (Partial)
Use the show interfaces configured command in the EXEC Privilege mode to view only configured 
interfaces. In Figure 20-2, GigabitEthernet interface 1/5 is in Layer 3 mode since 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. (Figure 158).
