Usage Guidelines
When the switch detects an EtherChannel misconfiguration, this error message appears:
PM-4-ERR_DISABLE: Channel-misconfig error detected on [chars], putting [chars] in
err-disable state.
To show switch ports that 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 shut down interface
configuration commands.
Examples
This example shows how to enable the EtherChannel guard misconfiguration feature:
