  定义主机名:
  cat2-3550(config)#hostname www.ChinaITLab.com
  
  登陆Banner:
  Cat1-3550(config)#banner login # Authorized Users elab Only #
  
  端口说明:
  cat2-3550(config)#int fa0/1
  cat2-3550(config-if)#description To www.gotolab.com 100M
  
  激活portfast:
  cat2-3550(config-if)#spanning cat2-3550(config-if)#spanning-tree portfast
  
  设置双工:
  cat2-3550(config)#int fa0/1
  cat2-3550(config-if)#duplex half
  
  设置端口速率:
  cat2-3550(config)#int fa0/1
  cat2-3550(config-if)#speed 10
  
  设置DNS:
  cat2-3550(config)#ip name-server 4.1.1.1
  
  设置 VTP Domain
  cat2-3550(config)#vtp domain hello
  cat2-3550(config)#vtp mode transparent
  
  创建VLAN:
  SW1(vlan)#vlan 10 name RED
  SW1(vlan)#vlan 20 name BLUE
  SW1(vlan)#exit
  
  设置VLAN优先级:
  SW1#config t
  SW1(config)#interface vlan 20
  SW1(config)#spanning-tree vlan 20 priority 20
  SW1(config-subif)#ip addr 1.1.1.1 255.255.255.0
  
  TRUNK设置:
  interface FastEthernet0/24
  switchport trunk encapsulation isl s
  witchport trunk allowed vlan 1,2,4,5,10,12-14,1002-1005 s
  witchport mode trunk no ip address
  
  显示trunk信息:
  cat2-3550#show interface trunk
  
  SPAN-TREE配置:
  Cat1-3550(config)#spanning-tree vlan 101 priority 0
  
  定义网关:
  SW1(config)#ip default-gateway 1.1.1.2
  
  创建etherchannel:
  First Switch:
  SW1(config)#int port-channel 1
  SW1(config-if)#switchport trunk encapsulation isl SW1(config-if)#switchport mode trunk
  
  SW1(config)#int fa 0/23
  SW1(config-if)#switchport trunk encap isl SW1(config-if)#switchport mode trunk SW1(config-if)#channel-group 1 mode auto
  
  SW1(config)#int fa 0/24
  SW1(config-if)#switchport trunk encap isl SW1(config-if)#switchport mode trunk SW1(config-if)#channel-group 1 mode auto
  
  Second Switch:
  SW2(config)#int port-channel 1
  SW2(config-if)#switchport trunk encapsulation isl SW2(config-if)#switchport mode trunk
  
  SW2(config)#int fa 0/23
  SW2(config-if)#switchport trunk encap isl
  SW2(config-if)#switchport mode trunk
  SW2(config-if)#channel-group 1 mode auto
  
  SW2(config)#int fa 0/24
  SW2(config-if)#switchport trunk encap isl
  SW2(config-if)#switchport mode trunk
  SW2(config-if)#channel-group 1 mode auto
  
  端口上划分VLAN:
  SW1(config)#int fastEthernet 0/2
  SW1(config-if)#switchport Access vlan 20
  SW1(config-if)#no shutdown
  
  SW1(config)#interface fastEthernet 0/3
  SW1(config-if)#switchport access vlan 10
  SW1(config-if)#no shutdown
  
  封装TRUNK:
  SW1(config)#int fa 0/1
  SW1(config-if)#switchport trunk encap isl SW1(config-if)#switchport mode trunk
  
  分配Ether Channel 到接口:
  SW1(config)#interface fa0/23
  SW1(config-if)#switchport trunk encapsulation dot1q
  SW1(config-if)#switchport mode trunk
  SW1(config-if)#channel-group 1 mode auto (other side use desirable)
  
  SW1(config)#interface fa0/24
  SW1(config-if)#switchport trunk encapsulation dot1q
  SW1(config-if)#switchport mode trunk
  SW1(config-if)#channel-group 1 mode auto (other side use desirable)
  
  配置SPAN:
  SW2#config t
  SW2(config)#no monitor session 1
  SW2(config)#monitor session 1 source interface fa0/3
  SW2(config)#monitor session 1 destination interface fa0/11 SW2(config)#end
  
  在VLAN接口上配置SPAN:
  SW2#config t
  SW2(config)#no monitor session 1
  SW2(config)#monitor session 1 source vlan 10
  SW2(config)#monitor session 1 destination interface fa0/11 (any encap here)
  SW2(config)#end
  SW2#sh monitor session 1 Session 1
