华为交换机Smart-link配置指南
前言
在2层网络中,我们一般会使用STP协议进行防环,但是STP检测机制是秒级的,对于对业务流量很敏感的网络中不一定适用,而接下来我们讲的Smart-link可满足要求,Smart-link可以实现毫秒级的网络切换。
网络拓扑

在Switch1交换机上配置Smart-link技术,g0/0/1作为master,g0/0/2作为standby,为保证网络的稳定性,不使能Smart-link的回切功能,在大型网络组网中,也不使用控制vlan发送flush报文;
配置思路
1.创建VLAN,并配置接口允许相应VLAN通过;
2.在SwitchA上创建Smart Link备份组,并指定端口角色;
3.在SwitchA上使能Smart Link组功能
配置命令参考
SwitchA
##创建VLAN,并配置接口允许相应VLAN通过;
<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 10 to 30
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type trunk
[SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 to 30
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type trunk
[SwitchA-GigabitEthernet0/0/2] port trunk allow-pass vlan 10 to 30
[SwitchA-GigabitEthernet0/0/2] quit
##在SwitchA上创建Smart Link备份组,并指定端口角色
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] stp disable
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] stp disable
[SwitchA-GigabitEthernet0/0/2] quit
[SwitchA] smart-link group 1
[SwitchA-smlk-group1] port gigabitethernet 0/0/1 master
[SwitchA-smlk-group1] port gigabitethernet 0/0/2 slave
##在SwitchA使能Smart Link组功能
[SwitchA-smlk-group1] smart-link enable
[SwitchA-smlk-group1] quit
查看Smart-link group命令
1.display smart-link group命令查看SwitchA上的Smart Link组信息
