Cisco4506

为了不影响用户对各种业务应用的连续不间断使用,在网络核心层和分布层网络设备上,都使用了备份的热备份功能。
Cisco4506A g1/1------Cisco4506B g1/1
Cisco4506A g2/1-------Cisco3750A g1/0/28
Cisco4506B g2/1-------Cisco3750B g1/0/28
Cisco3750A g1/0/1-----Server1 Eth0
Cisco3750A g1/0/2-----Server1 Eth0
Cisco3750B g1/0/1------Server Eth1
Cisco3750B g1/0/2------Server Eth1
Cisco3750A g1/0/25--------Cisco3750B g1/0/25
Server1 Eth2--------Server2 Eth2
hostname Cisco4506A
int g1/1
description link4506B_1/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan2
switchport mode trunk
int g2/1
description link3750A
switchport trunk encapsulation dot1q
switchport trunk allowed vlan2
switchport mode trunk
int vlan2
ip add 192.168.2.252 255.255.255.0
standy 2 ip 192.168.2.254
standy 2 ip 192.168.2.254
standy 2 priority 120
standy 2 preempt
Cisco4506B配置类似。
Cisco3750属于二层设备的配置
hostname Cisco3750A
int g1/0/1
description LinkServer1Eth0
switchport access vlan2
switchport mode access
int g1/0/2
description LinkServer1Eth1
switchport access vlan2
switchport mode access
int g1/0/25
description Link3750B_1/0/25
switchport trunk encapsulation dot1q
switchport trunk allowed vlan2
switchport mode trunk
int g1/0/28
description Link4506A
switchport trunk encapsulation dot1q
switchport trunk allowed vlan2
switchport mode trunk
int vlan 2
ip add 192.168.2.1 255.255.255.0
ip default-gateway 192.168.2.254
Cisco3750B配置类似。这是目前大、中型企业常用的一种部署模式。一般核心层的网络设备不会太多,也就2—4台,但分布层中的设备,如Cisco3750就会部署很多台。
