tmnxVrrpOperMasterDownTimer
Module: TIMETRA-VRRP-MIB
OID (symbolic): TIMETRA-VRRP-MIB::tmnxVrrpOperMasterDownTimer
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.20.1.1.1.13
Node type: OBJECT-TYPE
Type: TimeInterval
Access: read-only
Description: The value of tmnxVrrpOperMasterDownTimer specifies the current value of the Master Down Timer.
When a backup router receives a VRRP advertisement from a master, it resets this timer to the value of the Master Down Interval and begins to count down. If the backup router does not receive an advertisement till this timer times out, it will assume that the master is down and will declare itself to be the master.
What is tmnxVrrpOperMasterDownTimer?
Reports the live countdown value of the master-down timer, which resets to tmnxVrrpOperMasterDownInterval every time this backup router receives an advertisement from the master and counts down toward zero. If it reaches zero, the backup assumes the master has failed and takes over; watching this value trend toward zero without resetting is an early indicator of a master that has stopped advertising.
