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.

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.
