The value of tmnxDot1agCfmMaNetHoldDownTimer specifies the time, in
centiseconds, that a MEP in the association will delay declaring a
fault. This delay is added on to the existing
3.5 * dot1agCfmMaNetCcmInterval value used to determine if a
connectivity fault to the peer should be raised.
A value of zero (0) indicates that no additional delay should be
added to the existing 3.5 * dot1agCfmMaNetCcmInterval value.
