This reports the G.8032 guard timer for this logical ring, in milliseconds, the period after a protection switch during which the node ignores further RAPS PDUs to avoid reacting to stale or looped messages. A guard time set too short risks the ring reacting to a delayed or duplicated RAPS PDU as if it were a fresh event, potentially causing an unnecessary second switchover, while one set too long delays the ring's ability to respond to a genuinely new fault right after a prior one clears. For example, a guard time of 500 milliseconds would mean any RAPS PDU arriving within that half-second window after a switch is disregarded, preventing a flood of redundant switchover reactions.
