Module: Q-BRIDGE-MIB

OID (symbolic): Q-BRIDGE-MIB::dot1qForwardUnregisteredPorts

OID (numeric): 1.3.6.1.2.1.17.7.1.2.5.1.1

Node type: OBJECT-TYPE

Type: PortList

Access: read-only

Description: The complete set of ports in this VLAN to which multicast group-addressed frames for which there is no more specific forwarding information will be forwarded. This includes ports for which this need has been determined dynamically by GMRP, or configured statically by management.

What is dot1qForwardUnregisteredPorts?

This is a byte string listing ports that receive multicast frames for groups with no explicit membership—both statically configured and dynamically learned. Engineers check this to understand where unknown multicast traffic will flood when no group registration exists. This is a fallback destination for unmatched multicast.

Examples
