{% hint style="info" %}
The channel-group member has to match for member interfaces on the same switch.

However, it **doesn't** have to match the channel-group number on the other switch.

(**channel-group 1** on ASW1 can form an EtherChannel with **channel-group 2** on DSW1).

```
SW(config-id)# channel-group <number> mode <mode>
