swIGMPSnpCtrlRobustnessValue
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnpCtrlRobustnessValue
OID (numeric): 1.3.6.1.4.1.171.12.73.3.1.1.1.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This indicates the Robustness Value of the IGMP snooping in this VLAN. The default value is 2.
What is swIGMPSnpCtrlRobustnessValue?
This read-write integer (1-255, default 2) is the IGMP Robustness Variable, which tunes how many queries can be missed before the switch assumes a group or member has gone away. Admins raise it on lossy or congested networks to avoid prematurely aging out valid multicast subscribers, at the cost of slower leave detection. The default of 2 matches the IGMP RFC recommendation for typical LANs.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.1.1.15 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpCtrlRobustnessValue
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.3.1.1.1.15.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnpCtrlRobustnessValue.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.73.3.1.1.1.15.1 i <value>
