ETHCNTR Messages

This section contains the Ethernet controller messages. These messages appear when the switch software

fails to program the hardware that leads to incorrect switch behavior.

Error Message ETHCNTR-3-HALF_DUX_COLLISION_EXCEED_THRESHOLD: Collision at [chars]

exceed threshold. Consider as loop-back.

Explanation This message means that the collisions at a half-duplex port exceeded the threshold, and

the port is considered 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 This message means that a keepalive packet is 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 Check 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 entering

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

corrected. Although disabling keepalives prevents the port from being error-disabled, it does not

resolve the cause of the problem and can affect network stability. See CSCea46385 for more

information.

Error Message ETHCNTR-3-NO_HARDWARE_RESOURCES: Not enough hardware resources.

Shutting down [chars].

Explanation This message means that there are too many VLANs configured. [chars] is the short

interface name, such as Gi0/1h, or the VLAN name, such as VLAN0002.

Recommended Action Reduce the total number of VLANs to less than 1023. To preserve

configuration and connections across reboots, save the configuration.
