This value specifies, in bit-errors (0 to 11840), the threshold above which a tmnxDot1agCfmMepEthTestComplete notification is sent; a value of zero sends a notification on completion of any Eth-test regardless of errors found. An admin sets a nonzero threshold to avoid being paged for every routine test and only get notified when a test actually detects a meaningful number of bit errors. Setting this to zero is useful during initial validation testing where any completed test result, error-free or not, is of interest.
