3101 - Port is disabled as network loop is detected

Severity: MAJOR

Description: Because a network loop was detected on an Ethernet port, it has been disabled to avoid further service degradation.

Possible cause 1: More than one active uplink port or uplink Link Aggregation Group (LAG) from an uplink set has been assigned to the same network from the Virtual Connect domain to the external Ethernet switching environment, causing a network loop.

Possible cause 2: The incorrect configuration of the stacked links in multiple VC-Enet modules setup is causing a network loop.

Action: Administrative action is required to reconfigure the port where the network loop is being reported.
