Symptoms

If a trunk is created from interfaces that have lower than max speed (e.g., 100full-duplex on 1GbE links) adding a new interface fails. When this occurs, the system posts an error similar to the following: 01070619:3: Interface 1.4 media type is incompatible with other trunk members.

Impact

Interface cannot be added to the trunk.

Conditions

Interfaces use a lower speed then their capacity. Trunk is created where the highest speed of any of the members is this reduced speed. Interface, also lowered, is added to the trunk.

Workaround

Remove all interfaces, readd them all at the same time.

Fix Information

The BIG-IP system now correctly adds interfaces to a trunk formed from interfaces running at a lowered speed.
