rlIgmpSnoopEnable
Module: CISCOSB-rlBrgMulticast-MIB
OID (symbolic): CISCOSB-rlBrgMulticast-MIB::rlIgmpSnoopEnable
OID (numeric): 1.3.6.1.4.1.9.6.1.101.55.2.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Enable/Disable IGMP Snooping in the switch.
What is rlIgmpSnoopEnable?
This read-write TruthValue globally enables or disables IGMP snooping on the switch, the mechanism that watches IGMP membership reports to learn which ports have multicast listeners. An administrator enables this so multicast video or streaming traffic is only forwarded to ports that actually asked for it, instead of flooding every port. For example, enabling rlIgmpSnoopEnable on an IPTV deployment prevents multicast video streams from being blasted out every switch port and congesting unrelated links.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.55.2.2 snmpwalk -v2c -c public <target> CISCOSB-rlBrgMulticast-MIB::rlIgmpSnoopEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.55.2.2.1 snmpget -v2c -c public <target> CISCOSB-rlBrgMulticast-MIB::rlIgmpSnoopEnable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.6.1.101.55.2.2.1 s <value>
