c3600路由器查看和修改ip地址

1、可以先用下面的命令查看运行的网口：

show running-config

会显示下面的信息：

R1#show running-config

*Mar  1 00:42:04.095: %IP-4-DUPADDR: Duplicate address 192.168.254.4 on FastEthernet0/0, sourced by cc02.2f98                                                                                                                                .0000

R1#

可以看到FastEthernet0/0接口的ip地址了。

如果知道网卡的设备文件名，直接执行命令：

show int fa0/0

R1#show int fa0/0
FastEthernet0/0 is up, line protocol is up
  Hardware is AmdFE, address is cc01.2718.0000 (bia cc01.2718.0000)

R1#

也能看到地址。

2、修改地址：

完成。
