吴青峰被起诉思科⽹络配置交换机
接⼊层交换机:连接PC机
enable
config t
1、创建相应的vlan
vlan 10
2、连接终端的端⼝加⼊到相应的VLAN
interface range f0/1-2
switchport access vlan 10
exit
3、将交换机与交换机的端⼝配置成TRUNK
interface f0/3
switchport mode trunk
end
汇聚层交换机:
1、交换机与交换机相连的端⼝配置成trunk
Switch(config)#interface range f0/1-2
Switch(config-if-range)#sw m t
2、创建相应的vlan(本汇聚层交换机以下所有vlan)
Switch(config)#vlan 10
核⼼层交换机:
enable
conf t

vlan 20
vlan 30
interface range f0/1-3
switchport trunk en do
switchport mode trunk
exit

端⼝映射
端⼝映射:Router(config)#ip nat inside source static tcp 192.168.10.1 80 64.1.1.1 80 NAT
NAT上⽹的思路
1、内⽹做通(ok)
2、外⽹做通(ok)
3、采⽤NAT将内外⽹连通
NAT配置的位置:内⽹与外⽹相交的三层设备上进⾏配置
1、控制内⽹要上⽹的⽹段。
Router(config)#access-list 1 permit 192.168.10.0 0.0.0.255
Router(config)#access-list 1 permit 192.168.20.0 0.0.0.255
2、实现内⽹到外⽹的转换
Router(config)#ip nat inside source list 1 interface f0/1
inside source list 1 :内⽹要上⽹的⽹段
interface f0/1 (本路由器的外⽹接⼝)
3、指定本路由器内外⽹接⼝
Router(config)#interface f0/0
Router(config-if)#ip nat inside
Router(config-if)#exit
Router(config)#interface f0/1
Router(config-if)#ip nat outside
注意:内⽹所有的三层设备需要配置⼀个默认路由到公⽹:
Switch(config)#ip route 0.0.0.0 0.0.0.0 192.168.40.1
端⼝映射:Router(config)#ip nat inside source static tcp 192.168.10.1 80 64.1.1.1 80路由器
路由器端⼝设置ip
1.规划⽹段
2.配置ip
3.配路由协议(让路由层⾯互通)
