EtherChannel guard is enabled on the switch.

Usage Guidelines
When the switch detects a loop that is caused by an EtherChannel misconfiguration, this error message
appears:
PM-4-ERR_DISABLE: Channel-misconfig error detected on [chars], putting [chars] in
err-disable state.
To determine which switch ports are in the misconfigured EtherChannel, use the show interfaces status
err-disabled privileged EXEC command. To verify the EtherChannel configuration on a remote device,
use the show etherchannel summary privileged EXEC command on the remote device.
When a port is in the error-disabled state because of an EtherChannel misconfiguration, you can bring
it out of this state by entering the errdisable recovery cause channel-misconfig global configuration
command, or you can manually re-enable it by entering the shutdown and no shutdown interface
configuration commands.
Examples
This example shows how to enable the EtherChannel guard misconfiguration feature:
Switch(config)# spanning-tree etherchannel guard misconfig
You can verify your settings by entering the show spanning-tree summary privileged EXEC command.
