|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- C(state=absent) removes the portchannel config and interface if it
|
|
already exists. If members to be removed are not explicitly
|
|
passed, all existing members (if any), are removed.
|
|
- Members must be a list.
|
|
- LACP needs to be enabled first if active/passive modes are used.
