The next command is show interface ethernet 0; it reveals to us the
hardware address, logical address, and encapsulation method, as well as
statistics on collisions:
Router#sh int e0
Ethernet0 is up, line protocol is up
Hardware is Lance, address is 0010.7b7f.c26c (bia
0010.7b7f.c26c)
Internet address is 172.16.10.1/24
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set, keepalive set
(10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:08:23, output 00:08:20, 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
25 packets input, 2459 bytes, 0 no buffer
Received 25 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored,
0 abort
0 input packets with dribble condition detected
33 packets output, 7056 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
The most important statistic of the show interface command is the out-
put of the line and data-link protocol status. If the output reveals that Ethernet
0 is up and the line protocol is up, then the interface is up and running.
