tVrrpOpMasterDownInterval
Module: TIMETRA-VRRP-MIB
OID (symbolic): TIMETRA-VRRP-MIB::tVrrpOpMasterDownInterval
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.20.1.7.1.10
Node type: OBJECT-TYPE
Type: TimeInterval
Access: read-only
Description: The value of tVrrpOpMasterDownInterval indicates the time interval in milliseconds 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) * Master_Adver_Interval) / 256
What is tVrrpOpMasterDownInterval?
Reports the calculated time, in milliseconds, a backup router waits without hearing from the master before declaring it down, computed as three advertisement intervals plus a priority-weighted skew time. It's the dual-stack/v3 counterpart of tmnxVrrpOperMasterDownInterval, with the skew formula explicitly scaled by the master's advertisement interval.
