Change channel group mode without down time.

Hi All,

 

I'm trying to find a way to change the channel group mode on our access switch from mode on to mode active.

 

The port on access switch and core switch are configured like this : channel group X mode on

 

The goal is to change this config to channel group X mode active with no down time of the switch.

 

Please let me know if you have any ideas to do that.

 

Fabien.

I don't think its possible to change a Channel Group Mode without downtime.

Changing from On to Active will cause the port to start sending LACP messages in order to form an LACP Port-Channel.

As you are taking a link down, I suspect spanning-tree will also try and reconverge.

The downtime should be fairly minimal though, do you have a maintenance window?
