tmnxVrrpOperMasterDownInterval
Module: TIMETRA-VRRP-MIB
OID (symbolic): TIMETRA-VRRP-MIB::tmnxVrrpOperMasterDownInterval
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.20.1.1.1.12
Node type: OBJECT-TYPE
Type: TimeInterval
Access: read-only
Description: The value of tmnxVrrpOperMasterDownInterval specifies the time interval for the backup router to declare the master as down. It is calculated as (3 * Advertisement_Interval) + Skew_time where Skew_Time is calculated as (256 - Priority) / 256
What is tmnxVrrpOperMasterDownInterval?
Reports the calculated time (in milliseconds) a backup router waits without hearing from the master before declaring it down and taking over, computed per the VRRP spec as three advertisement intervals plus a priority-based skew time. Admins use this to understand roughly how long a failover will take to trigger after a real master outage.
