Huawei switch Smart-link Configuration Guide

Preface

stay 2 In the layer network , We usually use STP The agreement carries out anti ring , however STP The detection mechanism is second , It is not necessarily applicable to networks that are sensitive to business traffic , And then we talk about Smart-link Can meet the requirements ,Smart-link It can realize millisecond network switching .

Network topology

stay Switch1 Switch configuration Smart-link technology ,g0/0/1 As master,g0/0/2 As standby, To ensure the stability of the network , Do not enable Smart-link Failback function of , In large networks , Nor use controls vlan send out flush message ;

Configuration ideas

1. establish VLAN, And configure the interface to allow corresponding VLAN adopt ;
2. stay SwitchA To create a Smart Link Backup group , And specify the port role ;
3. stay SwitchA On enabling Smart Link Group functions

Configuration command reference

SwitchA

## establish VLAN, And configure the interface to allow corresponding VLAN adopt ;
<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

## stay SwitchA To create a Smart Link Backup group , And specify the port role 
[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

## stay SwitchA Can make Smart Link Group functions 
[SwitchA-smlk-group1] smart-link enable
[SwitchA-smlk-group1] quit
