I have discovered two ports in an etherchannel that have entered Suspended mode.

A redundant uplink is maintaining the switch's connection, but I would like to restore the ports.

What can cause this behavior and what is the recommended solution?

A suspended port can be causes by a mismatch in the configuration. i.e. one side configured as a trunk and the other an access port. Or one side a trunk allowing VLANs 1-5 and the other a trunk allowing 3-10.

The physical ports were allowing an additional subnet vs the etherchannel
