Hello - the cisco document states that:
EtherChannel Configuration Guidelines
Note
Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
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 6 EtherChannels on the switch stack.
- Configure a PAgP EtherChannel with up to eight Ethernet ports of the same type.
- Configure a LACP EtherChannel with up to16 Ethernet ports of the same type. Up to eight ports can be active, and up to eight ports can be in standby mode.
Maximum I have ever encountered has been 6.
Hope this helps
