EPM Messages Chapter 2 Messages and Recovery Procedures Error Message ENVIRONMENT-4-SECONDARY_OVERVOLT: [chars] Line Returns to Normal Range Current Voltage (mV): [dec] Explanation The voltage rail was higher than the maximum voltage threshold but is now within the normal range. [chars] is the voltage rail, and [dec] is the voltage. Recommended Action No action is required. Error Message ENVIRONMENT-4-SECONDARY_UNDERVOLT: [chars] Line Returns to Normal Range Current Voltage (mV): [dec] Explanation The voltage rail was lower than the minimum voltage threshold but is now within the normal range. [chars] is the voltage rail, and [dec] is the voltage. Recommended Action No action is required. EPM Messages Error Message EPM-6-AUTH_ACL: POLICY [chars]| EVENT [chars] Explanation The switch has sent or received a download request for a downloadable ACL (dACL). The first [chars] is the dACL policy, and the second [chars] is the event. Recommended Action No action is required. ETHCNTR Messages Error Message ETHCNTR-3-HALF_DUX_COLLISION_EXCEED_THRESHOLD: Collision at [chars] exceed threshold. Consider as loop-back. Explanation The collisions at a half-duplex port exceeded the threshold, and the port is treated as a loopback. [chars] is the port where the threshold was exceeded. Recommended Action No action is required. The port goes into error-disabled mode until the problem is resolved. Error Message ETHCNTR-3-LOOP_BACK_DETECTED:, Loop-back detected on [chars]. The port is forced to linkdown. Explanation A keepalive packet has been looped back to the port that sent the keepalive. The loopback condition might be caused by a balun cable being accidentally connected to the port, or there might be a loop in the network. [chars] is the port. Recommended Action Examine the cables. If a balun cable is connected, and the loopback condition is desired, No action is required. Otherwise, connect the correct cable, and bring the port up by using the no shutdown interface configuration command. We do not recommend using the no keepalive interface command to disable keepalives. The cause of this network loop must be found and 2-14 Cisco ME 3400E, ME 3400, and ME 2400 Ethernet Access Switch System Message Guide OL-23408-01
