swIGMPSnoopingGlobalState
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swIGMPSnoopingGlobalState
OID (numeric): 1.3.6.1.4.1.171.12.73.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This indicates the global state of IGMP snooping.
What is swIGMPSnoopingGlobalState?
This read-write switch turns IGMP snooping on or off for the entire device, independent of any per-VLAN setting (enabled(1)/disabled(2)). An admin uses it as the master kill switch: disabling it stops the switch from inspecting IGMP traffic on any VLAN and reverts to flooding multicast to every port. For example, briefly setting it to disabled(2) during troubleshooting helps confirm whether a multicast video stream failure is caused by snooping filtering a port rather than an upstream source problem.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.1.1 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnoopingGlobalState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.1.1.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swIGMPSnoopingGlobalState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.73.1.1.1 i <value>
