怎样用cisco命令查看路由器和路由器连接
R1# show cdp neighbors
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
R2 Eth 0/1 176 R S I 3640 Eth 0/2
R3 Fas 1/0 142 R S I 3560 Fas 0/0
show cdp neighbors 就很清楚了
1/0/0/0.1/1/1/1:2应该是子接口
ser全写是serial就是串口的意思,在做帧中继和单臂路由的时候会用到。由显示结果可以看出,R1的e0/1连接R2的e0/2,R2是台3640路由器。R1的f1/0连接R3的f0/0,R3是台3560交换机。
