This example shows how to display the status and configuration of Giga bit Eth erne t i nte rfac e 0/2:
Switch# show interfaces gigabitethernet0/2
GigabitEthernet0/2 is up, line protocol is up
Hardware is Gigabit Ethernet, address is 0002.4b29.4400 (bia 0002.4b29.4400)
Internet address is 192.20.135.21/24
MTU 1500 bytes, BW 100000 Kbit, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s
input flow-control is off, output flow-control is off
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:01, output 00:00:00, output hang never
Last clearing of "show interface" counters never
Queueing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
89245 packets input, 8451658 bytes, 0 no buffer
Received 81551 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 input packets with dribble condition detected
60387 packets output, 5984015 bytes, 0 underruns
0 output errors, 0 collisions, 16 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
This example shows how to display the status of all interfaces:
