host主机名配置

Switch#configure terminal 
Switch(config)#hostname S1
S1(config)#

 

禁用dns查询

Switch#configure terminal 
Switch(config)#no ip domain-lookup

 

vlan 配置

创建vlan

Switch(config)#vlan 2
Switch(config-if)#end
Switch#

 

vlan ip 配置

Switch(config)#interface vlan 2
Switch(config-if)#ip address 192.168.2.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config)#
Switch(config)#interface vlan 3
Switch(config-if)#ip address 192.168.3.1 255.255.255.0
Switch(config-if)#no shutdown 
Switch(config-if)#exit 
Switch(config)#
Switch(config)#end
Switch#show ip route 
Default gateway is not set

Host               Gateway           Last Use    Total Uses  Interface
ICMP redirect cache is empty

设置接口为access模式

设置接口为access模式,并加入vlan 10

S1(config)#inter fastEthernet 0/10
S1(config-if)#switchport mode access 
S1(config-if)#switchport access vlan 10
% Access VLAN does not exist. Creating vlan 10
S1(config-if)#no shutdown 
S1(config-if)#end
S1#

 

设置接口为tag vlan模式

Switch(config)#interface fastEthernet 0/23
Switch(config-if)#switchport trunk encapsulation dot1q 
Switch(config-if)#switchport mode trunk 
Switch(config-if)#exit
Switch(config)#

 

三层交换机开启路由功能

Switch#configure terminal 
Switch(config)#ip routing
Switch(config)#end
Switch#show ip route 
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR
       P - periodic downloaded static route

Gateway of last resort is not set

C    192.168.2.0/24 is directly connected, Vlan2
C    192.168.3.0/24 is directly connected, Vlan3
