Master Switch

This is a little guide about how to select in a stackable switches as a Master or Slave switch.

We are going to use command "stack priority".
By default, the stack priority of a member switch is 100.

A larger priority indicates a higher priority, meaning that a switch is more likely to be selected as a master switch.

For example, with command display stack, we will be able to check the priority of the switches, as on the following, if switch as is as a master switch, if it is reloaded, one of the switches that are on standby, will become as a new master switch. In order to avoid this problem we need to change the priority.

<HUAWEI> display stack
--------------------------------------------------------------------------------
MemberID Role     MAC              Priority   DeviceType         Description
--------------------------------------------------------------------------------
 0       Master   0004-9f31-d520   100        CE6850-48T4Q-EI 
 1       Standby  0004-9f62-1f40   100        CE6850-48T4Q-EI 
 2       Standby  0004-9f69-a391   100        CE6850-48T4Q-EI 
--------------------------------------------------------------------------------

 

Set the stack priority of the member switch that we want as a master.

<HUAWEI> system-view
[HUAWEI] stack slot 0 priority 150
Warning: Please do not frequently modify Priority because it will make the stack split. Continue? [Y/N]:y 
 
<HUAWEI> display stack
--------------------------------------------------------------------------------
MemberID Role     MAC              Priority   DeviceType         Description
--------------------------------------------------------------------------------
 0       Master   0004-9f31-d520   150        CE6850-48T4Q-EI 
 1       Standby  0004-9f62-1f40   100        CE6850-48T4Q-EI 
 2       Standby  0004-9f69-a391   100        CE6850-48T4Q-EI 
--------------------------------------------------------------------------------

 

Using that, we will not have trouble with choosing a switch to be as a Master.
