cisco设备配置基本知识

  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设备配置基本知识

  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 192.168.1.1 (DHCP服务器地址)

  cisco设备配置—PVST+配置:

  1.span 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 192.168.1.1 255.255.255.0 stan 2 ip 192.168.1.254 (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 192.168.1.1

  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 192.168.100.2 61.159.62.136

  端口映射:ip nat ins sou sta tcp 192.168.100.2 80 61.159.62.131 8080 extendable

  动态:acc 1 per 192.168.1.0 0.0.0.255

  ip nat pool test0 61.159.62.131 62.159.62.190 netmask 255.255.255.192 ip nat ins sou list 1 pool test0 overload PAT: acc 1 per 10.1.1.0 0.0.0.255 1.ip nat pool test1 61.159.62.131 61.159.62.131 netmask 255.255.255.148 ip nat ins sou list 1 pool test1 overload 2.ip nat ins sou list 1 int f0/0 overload

  cisco设备配置—RIP配置:

  router rip ver 2 no au- network 192.168.1.0 -----

  cisco设备配置—OSPF配置:

  router ospf 1 router-id 1.1.1.1 network 10.0.0.0 0.0.0.3 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)
