swIGMPSnpCtrlQuerierExpiryTime
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpCtrlQuerierExpiryTime
OID (numeric): 1.3.6.1.4.1.171.12.73.3.1.1.1.40
Node type: OBJECT-TYPE
Type: INTEGER

Description: This indicates the Querier Expiry Time of this VLAN.
What is swIGMPSnpCtrlQuerierExpiryTime?
This read-only integer (0-65535) counts down until the currently known querier is considered to have timed out, after which this VLAN's switch may take over the querier role if so configured. Admins use it to predict when a querier failover will occur, which matters because a gap without any querier means multicast group memberships stop being refreshed and can prematurely expire. A value that repeatedly resets close to its maximum indicates the real querier is healthy and still sending queries.
