cufwCluUnitHoldtime
Module: CISCO-UNIFIED-FIREWALL-MIB
OID (symbolic): CISCO-UNIFIED-FIREWALL-MIB::cufwCluUnitHoldtime
OID (numeric): 1.3.6.1.4.1.9.9.491.1.8.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: To determine unit health, the ASA cluster units send keepalive messages on the cluster control link to other units. The hold time that each unit will wait before declaring a peer unit as dead.
What is cufwCluUnitHoldtime?
This read-only INTEGER, ranging 800 to 45000 milliseconds, sets how long each unit waits, based on keepalive messages exchanged over the cluster control link, before declaring a peer unit dead. An admin tunes this to balance fast detection of a failed cluster member against tolerance for brief control-link hiccups. Setting this too short on a control link prone to occasional latency would risk an admin seeing units incorrectly declared dead and removed from the cluster.
