Multiple Registration Protocol settings
Multiple Registration Protocol (MRP) is an audio video bridging (AVB) feature. MVR is
a base registration protocol that enables devices running an MRP application to register
attributes to other devices in a network. MRP provides an application to register attributes
such as bandwidth for an audio-video (AV) stream and MAC address information. This
feature is used by various applications to propagate the registration.
Note: MRP framework must be available and enabled on all intermediate devices to
ensure that the propagation of the attributes occurs throughout the network.
The switch supports the following MRP applications:
Multiple MAC Registration Protocol (MMRP): MMRP allows for the propagation
MAC address information in the network, and allows for the registration and
deregistration of both individual MAC address information and group MAC address
membership. End stations can request to join or leave a multicast group, or to register
an individual MAC address with a specific VLAN. MAC address entries can be
dynamically registered and deregistered if MMRP is administratively enabled on the
switch.
Multiple VLAN Registration Protocol (MVRP): MVRP registers VLANs in the network,
enabling automatic VLAN configuration on the switch. In a typical network, VLAN
tagging is common. Many nodes require ingress traffic to be tagged with a specific
VLAN ID, and other nodes require egress traffic to be transmitted with a specific
