Description: Total number of times the Port Training state machine has failed the link error recovery process and downed the link.
What is ibPmaLinkDownedCntr?
Counts how many times the port's link training state machine failed error recovery and brought the link down entirely. This is a more severe signal than the recovery counter alone, since each increment means the port actually lost connectivity rather than just retraining.
