snIgmpGroupMembershipTime
Module: HP-SN-IGMP-MIB
OID (symbolic): HP-SN-IGMP-MIB::snIgmpGroupMembershipTime
OID (numeric): 1.3.6.1.4.1.11.2.3.7.11.12.2.6.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This is the time interval after which a group is considered inactive. For a router, snDvmrpEnable must have been set to 'enabled' before this object is writen. For a switch, snSwGroupIpMcastMode must have been set to 'enabled' before this object is writen.
What is snIgmpGroupMembershipTime?
This read-write value (1-7200 seconds, default 140) sets how long a multicast group is considered active before being aged out as inactive, and likewise requires multicast mode to already be enabled before it can be written. Admins tune it relative to the query interval to control how quickly stale multicast group memberships are cleaned up. For example, a device with a 60-second query interval and the default 140-second membership time will age out a group after roughly two missed queries.
