交换机常用命令使用方法

交换机常用命令使用方法
1．查看交换机的缺省配置
Switch＃show run
2.查看交换机端口属性
Switch＃show interface FastEthernet0/1
3.查看VLAN 属性
Switch＃show vlan
4.查看闪存目录
Switch＃driectory flash
5.查看IOS 版本
Switch＃show version
6.恢复交换机的缺省配置
Catalyst 2950Catalyst 1900
Switch＃delete falsh:vlan.dat Switch#delete nvram
Switch#erase startup-config
Switch#reload
7.指定交换机的IP地址和缺省网关
Catalyst 2950Catalyst 1900
Switch(config)#interface VLAN1
Switch(config-if)#ip address 192.168.0.2 255.255.255.0Switch(config)#ip address 192.168.0.2 255.255.255.0 Switch(config)#ip default-gateway 192.168.0.1 Switch(config)#ip default-gateway 192.168.0.1
8.设置端口属性
Catalyst 2950 Catalyst 1900
Switch(config)#interface FastEthernet0/2 Switch(config)#interface Ethernet0/2
Switch(config-if)#duples full Switch(config-if)#duples full
Switch(config-if)#speed 100 Switch(config-if)#speed 10
9.配置静态VLAN
Catalyst 2950Catalyst 1900
Switch#vlan database Switch(config)#vlan 2 name vlan2
Switch(vlan)#valn 2 vlan2Switch(config)#interface ethernet0/2
Switch(vlan)#exit Switch(config-if)#vlan-membership static 2
Switch(config)#interface fastethernet 0/2
Switch(config-if)#switchport access vlan 2
10.删除VLAN
Catalyst 1900Catalyst 2950
Switch(config)#no vlan 2Switch#vlan database
Swtich(vlan)#no vlan 2
11.配置VLAN间路由
Router 2621
Router(config)#interface fastethernetf0/1
Router(config)#no ip address
Router(config-if)#no shutdown
Router(config-if)#interface fastethernet0/1.1
Router(config-subif)#encapsulation dot1q 1
Router(config-sybif)#ip address 192.168.0.1 255.255.255.0
Router(config-subif)#encapsulation dot1q 2
Router(config-subif)#ip address 192.168.1.1 255.255.255.0
Router(config-subif)#exit
12.配置TRUNK
Catalyst 2950Catalyst 1900
Switch(config-if)#interface fastethernet0/2Switch(config)#interface fastethernet0/26 Switch(config-if)#switchport mode trunk Switch(config-if)#trunk on
13.配置VTP域
Catalyst 1900 Catalyst 2950
Switch(config)#vtp domain 123Switch(config)#vtp domain 123
Switch(config)#vtp server Switch(config)#vtp mode server
Switch(config)#vtp domain 123 Switch(config)#vtp domain 123
Switch(config)#vtp client Switch(config)#vtp mode client
14.查看ip
Catalyst 1900 Catalyst 2950
Switch#show ip Switch#show interface valn 1
15.查看VTP
Catalyst 1900 Catalyst 2950
Switch#show vtp status Switch#show show vtp status
