swMLDSnpFwdMemberPorts
Module: MCAST-SNOOPING-MIB
OID (symbolic): MCAST-SNOOPING-MIB::swMLDSnpFwdMemberPorts
OID (numeric): 1.3.6.1.4.1.171.12.73.2.2.1.1.4
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: This indicates the member port list of the MLD snooping forwarding entry.
What is swMLDSnpFwdMemberPorts?
This read-only PortList is the bitmap of ports the switch is forwarding a specific IPv6 (source, group) multicast stream to, the MLD/IPv6 counterpart of swIGMPSnpFwdMemberPorts. Admins use it to confirm a given port is actually receiving an IPv6 multicast stream before troubleshooting elsewhere. If a subscriber's port is missing from this list for an active IPv6 multicast channel, the issue is in MLD snooping/join handling, not downstream.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.2.1.1.4 snmpwalk -v2c -c public <target> MCAST-SNOOPING-MIB::swMLDSnpFwdMemberPorts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.73.2.2.1.1.4.1 snmpget -v2c -c public <target> MCAST-SNOOPING-MIB::swMLDSnpFwdMemberPorts.1
