ieee8021QBridgeForwardAllForbiddenPorts
Module: IEEE8021-Q-BRIDGE-MIB
OID (symbolic): IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeForwardAllForbiddenPorts
OID (numeric): 1.3.111.2.802.1.1.4.1.2.4.1.4
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 All Multicast Groups may not be dynamically registered by MMRP. 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 ieee8021QBridgeForwardAllStaticPorts. 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 ieee8021QBridgeForwardAllForbiddenPorts?
This object defines a set of VLAN ports where MMRP (Multiple MAC Registration Protocol) is forbidden from dynamically registering the 'Forward All Multicast Groups' service requirement. Network administrators configure this to manually prevent specific ports from adopting multicast flooding behavior, overriding automatic protocol decisions. This allows fine-grained control over which ports participate in dynamic multicast group registration within a VLAN.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.4.1.4 snmpwalk -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeForwardAllForbiddenPorts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.4.1.4.1 snmpget -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeForwardAllForbiddenPorts.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.111.2.802.1.1.4.1.2.4.1.4.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021QBridgeForwardAllForbiddenPorts.1
