LAG Master Config and Master Current are different


Userlevel 5
Hi

Have a pair of switches joined together via a LAG but the Config Master and the Current Master are different. I'm not sure why this is, or how to correct it, although I don't think its specifically doing any harm.

Here is currently how it looks:

Core1.1 # show sharing

Load Sharing Monitor
Config Current Agg Min Ld Share Flags Ld Share Agg Link Link Up
Master Master Control Active Algorithm Group Mbr State Transitions
================================================================================
24 21 LACP 1 L3_L4 A 21 Y A 1
L3_L4 22 Y A 1
L3_L4 23 Y A 1
L3_L4 24 Y A 1
================================================================================
[/code]
enable sharing 24 grouping 21-24 algorithm address-based L3_L4 lacp

Core2.1 # show sharing

Load Sharing Monitor
Config Current Agg Min Ld Share Flags Ld Share Agg Link Link Up
Master Master Control Active Algorithm Group Mbr State Transitions
================================================================================
24 21 LACP 1 L3_L4 A 21 Y A 1
L3_L4 22 Y A 1
L3_L4 23 Y A 1
L3_L4 24 Y A 3
================================================================================
[/code]
enable sharing 24 grouping 21-24 algorithm address-based L3_L4 lacp

Maybe this this is related to the LACP negotiation, or the way the ports come up - although I've not come across this before and for peace of mind rather it was right way around.

Perhaps I just need to shut them down and bring them back in the order I would like?

The switches are X440 G1's and running firmware version 16.2.3.5-patch1-3.

Many thanks in advance.

Hi Martin,

To my understanding, although a higher port number is configured, the lower port number will take up mastership in LAG.

Thanks Sushruth.
