hmIGMPSnoopAgingTime
Module: HMPRIV-MGMT-SNMP-MIB
OID (symbolic): HMPRIV-MGMT-SNMP-MIB::hmIGMPSnoopAgingTime
OID (numeric): 1.3.6.1.4.1.248.14.2.10.1.2.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The timeout period in seconds for aging out Multicast Groups dynamically learned with IGMP Snooping. Note that aging operates on a per interface per multicast group basis. This interval is also used to age out ports that have received IGMP Router Query PDUs. The default is 260 seconds and the range is 3 to 3600 seconds.
What is hmIGMPSnoopAgingTime?
This OID holds an integer between 3 and 3600 seconds that controls how long multicast group memberships learned by IGMP snooping remain active before being forgotten. Shorter times mean groups disappear faster if hosts stop announcing interest; longer times consume more memory. An operator would lower this value on networks with frequent group changes to reduce delay, or raise it on networks with unreliable hosts.
