Chapter 2 Message and Recovery Procedures

ETHCNTR Messages

Error Message EC-5-UNSUITABLE: [chars] will not join any port-channel, [chars].

Explanation

One of the interfaces cannot join the EtherChannel because it is configured for PortFast,

as a VLAN Membership Policy Server (VMPS), for IEEE 802.1x, as a voice VLAN, or as a

Switched Port Analyzer (SPAN) destination port. All of these are unsuitable configurations for

EtherChannels. The first [chars] is the interface name, and the second [chars] describes the details

of the unsuitable configuration.

Recommended Action Reconfigure the port; remove the unsuitable configuration.

ETHCNTR Messages

This section contains the Ethernet controller messages. These messages result from a failure of the

switch software when trying to program the hardware and lead to incorrect switch behavior.

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

This message occurs when 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 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

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

There are too many VLANs and routed ports (if the switch supports routed ports)

configured. [chars] is the short interface name, such as Gi0/1, or the VLAN name, such as

VLAN0002.

Recommended Action Reduce the total number of VLANs and routed ports to less than 1023. To

preserve configuration and connections across reboots, save the configuration.
