Add Adapter to Running Etherchannel

First we want to make sure that the adapter we want to add does not have an ip address on it. If so we need to remove the ip configuration from it and then we can add it to our etherchannel.

Lets say we have an etherchannel ent5 for example and it already has ent1 and ent3 as primary adapters. You want to add ent0 as a primary adapter as well. Here is what we would do first.

smitty etherchannel




select your etherchannel --> in our example it would be ent5

Next your given a screen like this:



You will scroll down to Add Main Adapter

hit f4 to display your adapters



select the adapter you want to add --> in our example ent0

hit enter when done
It will then display if it failed or if succeeded.

Now to verify that it was added to your etherchannel you can do the following command:

lsattr -El ent5
The first line you see will show the adapters that are setup as primary adapters:



adapter_names ent0,ent1,ent3 EtherChannel Adapters True
