【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

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
