【说明】

本命令输出的信息很多，平时故障排查时，主要观察接口下是否有error报文，接口状态是否up，有没有载波丢失，双工、速率、MTU等信息是否正常。

2. 查看接口的概要信息

user@MX960> show interfaces terse

Interface Admin Link Proto Local Remote ge-0/0/0 up up

ge-0/0/0.0 up up bridge ge-0/0/1 up up

ge-0/0/1.0 up up bridge ge-0/0/2 up down

ge-0/0/2.0 up down multiservice ---(more 19%)---[abort]

【说明】

本命令可以检查接口的状态，以及该接口工作在二层（bridge）还是三层（inet/inet6）。

3. 实时监控接口报文转发状态

user@MX960> monitor interface ge-0/0/0

re0-SNNU-CA-CORE-2 Seconds: 18 Time: 18:22:29 Delay: 5/0/5 Interface: ge-0/0/0, Enabled, Link is Up Encapsulation: Ethernet, Speed: 1000mbps

Traffic statistics: Current delta Input bytes: 145213786382 (2605032 bps) [8202565] Output bytes: 57042305177 (167296 bps) [2271679] Input packets: 150728829 (288 pps) [7993] Output packets: 112576312 (209 pps) [6570] Error statistics:

Input errors: 0 [0] Input drops: 0 [0] Input framing errors: 0 [0] Policed discards: 0 [0] L3 incompletes: 0 [0] L2 channel errors: 0 [0] L2 mismatch timeouts: 0 [0] Carrier transitions: 5 [0] Output errors: 0 [0] Output drops: 0 [0] Aged packets: 0 [0] Active alarms : None Active defects: None

Input MAC/Filter statistics:

Unicast packets 186056424 [7750] Broadcast packets 820253 [27]

Multicast packets 774591 [41] Oversized frames 0 [0] Packet reject count 409324 [51] DA rejects 0 [0] SA rejects 0 [0] Output MAC/Filter Statistics:

Unicast packets 150677786 [6170] Broadcast packets 2457091 [82] Multicast packets 1557774 [50] Packet pad count 0 [0] Packet error count 0 [0] 【说明】

本命令可以实时查看接口的报文转发流量。

4. 清除动态生成的vlan接口

user@MX960>clear auto-configuration interfaces xe-0/2/1

【说明】

本命令可以手动清除动态生成的VLAN接口，慎用！

如接口下有分配的DHCP地址，则接口无法清除。可用如下方法清除 set interfaces ge-4/0/2 disable commit

run clear dhcp server binding interface ge-4/0/2.1073892537 run clear dhcpv6 server binding interface ge-4/0/2.1073892537 run clear auto-configuration interfaces ge-4/0/2 delete interfaces ge-4/0/2 disable commit

三、用户相关
