You can manually config RMON events and alarms on the routers to watch the dot3StatsFCSErrors and dot3StatsSingleCollisionFrames for the interface in which you're interested. See http://www.cisco.com/en/US/tech/tk961/technologies_configuration_example09186a0080094478.shtml for more on setting up RMON events and alarms from the CLI.
