Ever had this error before on a Cisco 6500 catalyst?

The TestUnusedPortLoopback test verifies the data path between the supervisor engine and the network ports of a module in the runtime periodically. The TestUnusedPortLoopback test verifies the data path between the supervisor engine and the network ports of a module in the runtime periodically. In this test, a Layer 2 packet is flooded onto the VLAN which only the test port and the supervisor’s inband port are part
of. The packet loops back in the port and returns to the supervisor on that same VLAN. It’s similar to TestLoopback but only runs on unused (admin down) network ports and only one unused port per port ASIC. It serves to substitute the lack of nondisruptive loopback test in current ASICs. The test runs every 60 seconds.
It is a Nondisruptive test health-monitoring .
This indicates that this issue is related to port 1 on module 1, i.e. Gi1/1. This is a cosmetic bug, the details are available here: Bug ID: CSCso32839
By unshutting and leaving the port unshut, the alarm is cleared.
