dot1dPortRestrictedGroupRegistration
Module: P-BRIDGE-MIB
OID (symbolic): P-BRIDGE-MIB::dot1dPortRestrictedGroupRegistration
OID (numeric): 1.3.6.1.2.1.17.6.1.4.1.1.4
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: The state of Restricted Group Registration on this port. If the value of this control is true(1), then creation of a new dynamic entry is permitted only if there is a Static Filtering Entry for the VLAN concerned, in which the Registrar Administrative Control value is Normal Registration. The value of this object MUST be retained across reinitializations of the management system.
What is dot1dPortRestrictedGroupRegistration?
Setting this object to true(1) restricts a bridge port so new dynamic GMRP multicast group entries can only be created if a matching static filtering entry with Normal Registration already exists for that VLAN. An administrator enables this on ports facing untrusted or edge devices to prevent unauthorized hosts from dynamically joining arbitrary multicast groups. For example, setting dot1dPortRestrictedGroupRegistration to true(1) on a guest-facing port stops a rogue device from registering itself into a sensitive multicast video stream it wasn't statically permitted to join.
