思科HSRP和Port-channel配置

Posted 2020-08-31 myway_liang

如下图示： 

实验目标：建立核心交换机vlan 39,并且执行HSRP，两交换机用聚合接口连线。PC1能与PC2互通。

Coresw1:
vlan database
   vlan 39
   exit
config t
hostname coresw1
port-channel load-balance dst-mac
int vlan39
  ip add 10.39.39.251 255.255.255.0
  ip helper-address 10.39.39.39  //指定DHCP服务器
  standby 39 ip 10.39.39.254  //VLAN39网关
  standby 39 priority 150   //优先级越高越抢占为主网关
  standby 39 preempt   //抢占
  exit
int f1/0   //接PC1接口
  switchport access vlan 39
  duplex full
  speed 100
  no sh
  exit
interface Port-channel1
  switchport mode trunk
  no sh
  exit
int range f0/14 - 15  //两核心交换机连接聚合口
  switchport mode trunk 
  duplex full 
  speed 100
  channnel-group 1 mode on
  no sh
  exit

 

Coresw2:
vlan database
   vlan 39
   exit
config t
hostname coresw2
port-channel load-balance dst-mac
int vlan39
  ip add 10.39.39.252 255.255.255.0
  ip helper-address 10.39.39.39  //指定DHCP服务器
  standby 39 ip 10.39.39.254  //VLAN39网关
  standby 39 priority 130   //优先级越高越抢占为主网关
  standby 39 preempt   //抢占
  exit
int f1/0   //接PC2接口
  switchport access vlan 39
  duplex full
  speed 100
  no sh
  exit
interface Port-channel1
  switchport mode trunk
  no sh
  exit
int range f0/14 - 15  //两核心交换机连接聚合口
  switchport mode trunk 
  duplex full 
  speed 100
  channnel-group 1 mode on
  no sh
  exit
