hm2L2McastSnoopingQueryPortsAutoPortsState
Module: HM2-L2MCAST-MIB
OID (symbolic): HM2-L2MCAST-MIB::hm2L2McastSnoopingQueryPortsAutoPortsState
OID (numeric): 1.3.6.1.4.1.248.11.33.1.1.1.1.1.4
Node type: OBJECT-TYPE
Type: PortList
Access: read-write
Description: The set of ports that are allowed to be learned automatically by LLDP protocol to be IGMP query ports for this VLAN.
What is hm2L2McastSnoopingQueryPortsAutoPortsState?
This read-write bitmap controls which ports are permitted to be automatically learned via LLDP as IGMP query ports for a VLAN. Admins use this to restrict auto-learning to specific trusted ports, preventing an unintended port from being treated as a multicast query port. For example, clearing this bitmap on all but the known uplink ports prevents a rogue device on an access port from being mistakenly auto-learned as a querier.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.33.1.1.1.1.1.4 snmpwalk -v2c -c public <target> HM2-L2MCAST-MIB::hm2L2McastSnoopingQueryPortsAutoPortsState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.33.1.1.1.1.1.4.1 snmpget -v2c -c public <target> HM2-L2MCAST-MIB::hm2L2McastSnoopingQueryPortsAutoPortsState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.33.1.1.1.1.1.4.1 s <value>
