Mailing List Archive: Gracefully remove port from LAG on CER/MLX?

Hey all,

I'm looking to remove one port from an already established LAG group with
1Gbps of traffic on it. I don't want the traffic to just fall on the floor.
I'm wondering if anyone has any confirmation whether disabling a port will
work in any sort of graceful manner, or if I should plan for the worst. I'm
inclined to think it will be service affecting but just curious if there is
some 'magic' to this.

I want to do this on CER platform right now, but also want to know for
general knowledge how this works on MLX platform as well.

Thanks

It is supposed to be graceful (add or remove member inside a LAG),
*except* if it is the primary port. If it's the case, you will have to
completely undeploy the LAG, reconfigure it, and re-deploy it.

You can disable the port inside the LAG config, before removing it.
