EtherChannel Configuration Guidelines
If improperly configured, some EtherChannel ports are automatically disabled to avoid network loops and
other problems. Follow these guidelines to avoid configuration problems:
•
Do not try to configure more than 24 EtherChannels on the switch or switch stack.
•
In a mixed switch stack that contains one or more Catalyst 2960-S switches, do not configure more than
six EtherChannels on the switch stack.
•
Configure a PAgP EtherChannel with up to eight Ethernet ports of the same type.
