Chapter 2 Message and Recovery Procedures

ETHCNTR Messages

This section contains the Ethernet controller messages. These messages are a result of 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 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].

Explanation

A loopback condition might be the result of a balun cable incorrectly connected to a

port. [chars] is the interface name.

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 then enable the port.

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

Shutting down [chars].

Explanation

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.

GBIC_SECURITY Messages

This section contains the Cisco Gigabit Interface Converter (GBIC) and small form-factor pluggable

(SFP) module security messages. The GBIC and SFP modules have a serial EEPROM that contains the

serial number, security code, and cyclic redundancy check (CRC). When the module is inserted into the

switch, the software reads the EEPROM to recompute the security code and CRC. The software

generates an error message if the CRC is invalid or if the recomputed security code does not match the

one stored in the EEPROM.

Note The switch supports SFP modules and does not support GBIC modules. Although the error message text

refers to GBIC interfaces and modules, the messages from the switch actually refer to the SFP module

interfaces and modules.
