Usage Guidelines
If you do not specify a channel group, all channel groups are displayed.
In the output below, the Passive port list field is displayed for Layer 3 port channels only. This field
means that the physical interface, which is still not up, is configured to be in the channel group (and
indirectly is in the only port channel in the channel group).
