Using show Commands to Display Interface Information
To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/adapter/port].
Following is a
Router# sh int fastethernet 2/0/0
FastEthernet2/0/0 is administratively down, line protocol is down
Hardware is cyBus FastEthernet Interface, address is 0000.0ca5.2380 (bia 0000)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255
Encapsulation ARPA, loopback not set, keepalive set (10 sec), hdx, 100BaseTX
(additional displayed text omitted from this example)
With the show interfaces [type slot/adapter/port] command, use arguments such as the interface type (fastethernet, and so forth) and the port number (slot/port) to display information about a specific interface only, as in the following example of the show interfaces fastethernet command, which shows information specific to the first interface on an FEIP in interface processor slot 2:
Router# show interfaces fastethernet 2/0/0
FastEthernet2/0/0 is administratively down, line protocol is down
Hardware is cyBus FastEthernet Interface, address is 0000.0ca5.2380 (bia 0000) MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec), hdx, 100BaseTX ARP type: ARPA, ARP Timeout 4:00:00
