Command History
Usage Guidelines If you do not specify a channel-group, all channel groups appear.
In the output, the Passive port list field appears only for Layer 3 port channels. 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).
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
