通常我们使用show inte***ce命令来查看接口的信息，如show inte***ce gig 1/0或者show int pos 2/0等来分别查看路由器上千兆以太接口和POS接口的端口信息。 　　查看以太网接口信息，在7507上使用命令为：show inte***ces fastethernet [slot/port-adapter/port]　　查看POS接口信息，在7507上使用命令为：show inte***ces pos [slot/port-adapter/port]　　1、下例给出了在7507上查看第1槽位上第1个PA上的第1个快速以太网接口的接口配置信息：Router# show inte***ces fastethernet 1/0/0Fast Ethernet1/0/0 is up, line protocol is up Hardware is TSWITCH, address is 00e0.f7a4.5130 (bia 00e0.f7a4.5130)MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255Encapsulation ARPA, loopback not set, keepalive set (10 sec)Half-duplex, 100BaseTXARP type: ARPA, ARP Timeout 04:00:00Last input 00:05:30, output 00:00:00, output hang neverLast clearing of "show inte***ce" counters neverQueueing strategy: fifoOutput queue 0/40, 0 drops; input queue 0/75, 0 drops5 minute input rate 0 bits/sec, 0 packets/sec5 minute output rate 0 bits/sec, 0 packets/sec312 packets input, 18370 bytes, 0 no bufferReceived 216 broadcasts, 0 runts, 0 giants, 0 throttles3 input errors, 0 CRC, 0 frame, 0 overrun, 3 ignored, 0 abort0 input packets with dribble condition detected15490 packets output, 1555780 bytes, 0 underruns2 output errors, 0 collisions, 2 inte***ce resets0 babbles, 0 late collision, 0 deferred0 lost carrier, 0 no carrier 2 output buffer failures, 0 output buffers swapped out　　2、下例给出了在7507上查看第2槽位上第1个PA上的第1个快速以太网接口的接口配置信息： Router# show inte***ces pos 2/0/0POS2/0/0 is up, line protocol is upHardware is cyBus Packet over SonetDescription: PRI-T1 net to zippy (4K) to Pac-BellInternet address is 10.1.1.1/27MTU 4470 bytes, BW 1000 Kbit, DLY 40000 usec, rely 255/255, load 1/255Encapsulation HDLC, loopback not set, keepalive set (3 sec)Last input 00:00:00, output 00:00:00, output hang neverLast clearing of "show inte***ce" counters 00:23:09Queueing strategy: fifoOutput queue 0/40, 0 drops; input queue 0/75, 0 drops5 minute input rate 0 bits/sec, 1 packets/sec5 minute output rate 1000 bits/sec, 1 packets/sec1046 packets input, 54437 bytes, 0 no bufferReceived 485 broadcasts, 0 runts, 0 giants, 0 parity0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort4013 packets output, 1357412 bytes, 0 underruns0 output errors, 0 applique, 0 inte***ce resets       1/3 123下一页尾页
