dot1qForwardUnregisteredForbiddenPorts

Module: Q-BRIDGE-MIB

OID (symbolic): Q-BRIDGE-MIB::dot1qForwardUnregisteredForbiddenPorts

OID (numeric): 1.3.6.1.2.1.17.7.1.2.5.1.3

Node type: OBJECT-TYPE

Type: PortList

Access: read-write

Description: The set of ports configured by management in this VLAN for which the Service Requirement attribute Forward Unregistered Multicast Groups may not be dynamically registered by GMRP. This value will be restored after the device is reset. A port may not be added in this set if it is already a member of the set of ports in dot1qForwardUnregisteredStaticPorts. The default value is a string of zeros of appropriate length.

The value of this object MUST be retained across reinitializations of the management system.

What is dot1qForwardUnregisteredForbiddenPorts?

This is a writable byte string blocking ports from dynamically registering to receive unregistered multicast via GMRP. Engineers configure this to prevent ports from receiving unknown multicast traffic even if they request it. Ports here will never join the unregistered multicast group.

Examples
