2、使用： 

[root@localhost eversec]# sh hhh ------------------------------------------------------------------------------------------------------------ |NO |Device |Status |Type |Speed |Ipaddr |Mask |Bcast | ------------------------------------------------------------------------------------------------------------ |0 |lo |up |- |- |127.0.0.1 |255.0.0.0 |- | |1 |eth0 |up |TP |1000Mb/s |10.233.253.66 |255.255.255.248 |10.233.253.71 | |2 |eth1 |up |TP |1000Mb/s |172.16.7.74 |255.255.255.248 |172.16.7.79 | |3 |eth2 |up |FIBRE |10000Mb/s |- |- |- | |4 |eth3 |up |FIBRE |10000Mb/s |- |- |- | |5 |eth1.3003@eth1 |- |- |- |- |- |- | |6 |eth1.3005@eth1 |- |- |- |- |- |- | |7 |eth1.3015@eth1 |- |- |- |- |- |- | |8 |eth1.3115@eth1 |- |- |- |- |- |- | ------------------------------------------------------------------------------------------------------------

 3、注解： 

NO： 序號
Device: 網卡名稱
Status: 網卡狀態
Speed： 速度 Type: 網卡類型（光口：FIBRE、電口：TP） Ipaddr: ip地址 Mask: 掩碼
Bcast: 廣播地址
