2）查看PC2的IP信息

copytextpop-up

PC>ipconfig /all
FastEthernet0 Connection:(default port)
Connection-specific DNS Suffix..:

3）在查看交换机sw1的mac地址表

copytextpop-up

Switch#hostname SW1
SW1#show mac-address-table

1 0010.1148.9309 DYNAMIC Fa0/24

1 00e0.b079.7815 DYNAMIC Fa0/1

步骤二：查看交换机sw1邻居信息

1）更改交换机sw2的主机名

copytextpop-up

Switch>enable
SW2#configure terminal
SW2(config)#hostname SW2
SW2(config)#

Switch>enable

SW2#configure terminal

SW2(config)#hostname SW2

SW2(config)#

2）进入交换机SW1特权模式通过命令查看CISCO设备邻居信息：

copytextpop-up

Switch#show cdp neighbors
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone
Device ID Local Intrfce Holdtme Capability Platform Port ID
SW2 Fas 0/24 174 S 2950 Fas 0/9

Switch#show cdp neighbors

Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge

S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone

Device ID Local Intrfce Holdtme Capability Platform Port ID

SW2 Fas 0/24 174 S 2950 Fas 0/9

2：配置接口速率及双工模式

3.2 方案

网络拓扑图如图-3

图-3

3.3 步骤

实现此案例需要按照如下步骤进行

步骤一：配置交换机接口模式

1）配置路由器R1的接口IP作为192.168.1.0网段的网关地址

copytextpop-up

Router>enable
Router#configure terminal
Router(config)#interface fastEthernet 0/0
Router(config-if)#ip address 192.168.1.100
Router(config-if)#ip address 192.168.1.100 255.255.255.0
Router(config-if)#no shutdown

Router>enable

Router#configure terminal

Router(config)#interface fastEthernet 0/0

Router(config-if)#ip address 192.168.1.100

Router(config-if)#ip address 192.168.1.100 255.255.255.0

Router(config-if)#no shutdown

2）配置交换机管理IP和网关地址

copytextpop-up

Switch(config)#interface vlan 1
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config)#ip default-gateway 192.168.1.100

Switch(config)#interface vlan 1

Switch(config-if)#ip address 192.168.1.1 255.255.255.0

Switch(config-if)#no shutdown

Switch(config-if)#exit

Switch(config)#ip default-gateway 192.168.1.100

3）用ping命令进行测试
