на cisco.com: 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. Most of these errors lead to incorrect switch behavior, and you should call your Cisco technical support representative.
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.
К порту подключен хаб и непонятно, что он мог такое утворить, что порт перешел в err-disable ?
Может я чего-то неправильно понял, но написано что если "слишком много коллизий", то считаем что случился "loopback". А за-loop-ившийся порт переводится в err-disable. Причина коллизий - вероятно, слишком много от HUB-а захотели... =================================================================== uanog mailing list.
