cisco设备配置的.步骤大家掌握了吗?相信只要按照下面的操作,一定可以达到我们想要的实验结果,更重要的就是希望大家已经掌握了cisco的配置知识。
cisco设备配置—前提配置:
en conf t no ip domain-lookup line con 0 logg syn exec-time 0 0 exit host r1
cisco设备配置—VTP配置:
vtp domain domain_name vtp mode server/client/transparent vtp password password vtp pruning vtp version 2
查看VTP配置:show vtp status
cisco设备配置—VLAN配置:
vlan database (特权模式) vlan 2 name caiwubu exit vlan 2 (全局模式)
查看VLAN配置:show vlan brief
cisco设备配置—VLAN Trunk配置:
swit trunk encapsulation isl/dot1q/negotiate (接口里面,封装类型) swit mode trunk
查看配置:show int f0/1 swit
以太网通道:
int rang f0/1 -f0/10 swit mode trunk chan lacp;pagp channel-group 1 mode on exit
cisco设备配置—三层交换配置:
ip routing no swt (改为路由接口) ip helper-add (DHCP服务器地址)
cisco设备配置—PVST+配置:
vlan 2,4-6 pri 4096(倍数0-32768) 2. root pri/sec span vlan 2 cost 150 (0-255) span vlan 2 por *
查看配置:show span show span vlan * d
cisco设备配置—HSRP配置:
int vlan 2 ip add stan 2 ip (虚拟的IP地址) stan 2 pri 150 (0-255) stan 2 pree stan 2 track int f1/0 100
查看HSRP:show stan b
cisco设备配置—ACL配置:
标准:acc 1(1-99) per(pre den) source(数据源地址)
int f0/0 ip nat inside int f1/0 ip nat outside int f0/0 ip acc 1 in
扩展:acc 101(100-199) per(pre/den) protocol(协议) 源地址 目标地址 --
命名:ip acc stan/ext test
per/den host
定时:time-range mytie
per wee 8:30 to 17:30
acc ....... time-range mytie
查看:show acc
cisco设备配置—NAT配置:
静态:ip nat ins sou sta
端口映射:ip nat ins sou sta tcp 80 8080 extendable
动态:acc 1 per
ip nat pool test0 netmask ip nat ins sou list 1 pool test0 overload PAT: acc 1 per nat pool test1 netmask ip nat ins sou list 1 pool test1 overload nat ins sou list 1 int f0/0 overload
cisco设备配置—RIP配置:
router rip ver 2 no au- network -----
cisco设备配置—OSPF配置:
router ospf 1 router-id network area 0
末梢区域:area 1 stub
完全末梢区域:area 1 stub no-su
ness:area 1 nssa
完全ness:area 1 nssa no-su
路由重分发:
router rip red ospf 1 metric 10 router ospf 1 red rip subnets def-in orig (默认) red sta subnets (静态) red conn subnets (直连)
