The value of tmnxDot1agCfmGracePeriod indicates whether or not the node is locally executing a grace period. A value of 'true' indicates that all peer timeouts are extended locally and eligible MEPs are transmitting grace period information. A value of 'false' indicates no grace period information is transmitted and standard values are used for timing out remote peers. Note that for a local MEP to be eligible for grace period transmission it must be admin up and ccm-enabled. Additionally, for any transmission to occur tmnxDot1agCfmGraceTxEnable must be set to 'true'.
