tmnxVrrpOperMasterSince
Module: TIMETRA-VRRP-MIB
OID (symbolic): TIMETRA-VRRP-MIB::tmnxVrrpOperMasterSince
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.20.1.1.1.9
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: The tmnxVrrpOperMasterSince, in case of a virtual router which is the current master, is the sysUpTime when operational state (vrrpOperState) of the virtual router changed to master(3). In case of a backup virtual router, this value specifies the sysUpTime when it received the first VRRP advertisement message from the virtual router which is the current master.
What is tmnxVrrpOperMasterSince?
For the current master, reports the sysUpTime when this instance last transitioned into the master role; for a backup, it reports when it first heard an advertisement from the current master. Admins use it to gauge VRRP stability -- a master-since value that keeps resetting indicates flapping between master and backup, worth investigating.
