What is swL2IGMPRouterForbiddenPortList?
A bitmap of ports explicitly barred from ever being treated as a multicast router port on this VLAN, even if IGMP query traffic is seen on them; the source DESCRIPTION is empty, so this reading is inferred from the object name and its role alongside the static and dynamic router-port lists. Admins use this to stop an access port from being mistakenly promoted to router-port status by spoofed or accidental query traffic.
Examples
Walk all instances (SNMPv2c):

Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.70.2.2.11.6.1.4.1 snmpget -v2c -c public <target> DGS3427-L2MGMT-MIB::swL2IGMPRouterForbiddenPortList.1
