Like 802.1AS, Multiple Registration Protocol (MRP) is an Audio Video Bridging (AVB) feature that is available on some TejNOS-EN platforms. 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 requirement for a given AV stream and MAC address information. It is used by various applications to propagate the registration. TejNOS-EN switches support the following MRP applications:
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 may 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.
MSRP reserves necessary resources in the network to facilitate time sensitive traffic to flow end to end. In a typical network, there are multiple Talkers (those who transmit streams) and multiple Listeners (those who receive streams from one or many Talkers). Each flow has specific bandwidth, frame rate, and time sync requirements. With the use of MSRP these resources are guaranteed through all intermediate devices that are between any talker and listener.
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 specific VLAN ID, and other nodes require egress traffic to be transmitted with a specific VLAN ID. With the use of MVRP on both ingress and egress, no manual VLAN configuration is required to pass tagged traffic through the network.
NOTE: MRP framework must be available and enabled in all intermediate devices to ensure that the propagation of the attributes occurs throughout the network.
With MRP, network attributes are declared, registered, withdrawn, and removed completely dynamically without any user intervention. This dynamic nature is especially useful in networks where:
Use the MRP Configuration page to configure global MRP settings for the switch. To access the basic MRP Configuration page click Switching > MRP > MRP Configuration.
NOTE: The fields available on the MRP Configuration page vary based on the platform and its supported features.

Use the Qav Parameters page to configure and view the per-port IEEE 802.1Qav settings. The IEEE 802.1Qav standard supports time-sensitive traffic streams by pacing all switch traffic, including legacy asynchronous Ethernet traffic, through queuing and forwarding. When a Talker declares a stream, it identifies whether the stream is Class A or Class B and specifies the stream’s bandwidth requirements. Class A traffic has a higher transmission priority than Class B traffic.
On the Qav Parameters page, you can view and configure selected bandwidth allocations for Class A and Class B traffic. To display the Qav Statistics page click Switching > MRP > Qav Parameters.
To configure Qav parameters, select the check box next to the port to configure and edit the fields as desired. You can select multiple ports to apply the same settings to the selected interfaces.

MSRP Streams Information Fields
Field |
Description |
|---|---|
Stream ID |
A 16-bit unsigned integer value, Unique ID, used to distinguish among multiple streams sourced by the same system. |
Stream Source MAC Address |
Identifies the MAC address of the traffic stream’s source. |
Received Accumulated Latency |
The 32-bit unsigned Accumulated Latency component is used to determine the worst-case latency that a Stream can suffer in its path from the Talker to a given Listener. It starts as a 0 in a Talker Advertise Declaration at the Talker, and its value is increased by each Bridge as the Talker Advertise Declaration propagates through the network. |

Identifies whether the stream is Class A or Class B. Class A traffic has a higher priority than Class B traffic. |
Rank |
The 5-bit unsigned Rank component is used by systems to decide which streams can and cannot be served, when the MSRP registrations exceed the capacity of a Port to carry the corresponding data streams. If a Bridge becomes oversubscribed the Rank will also be used to help determine which Stream or Streams can be dropped. A lower numeric value is more important than a higher numeric value. |

The 32-bit unsigned Bandwidth component is used to allocate resources and adjust queue selection parameters in order to supply the quality of service requested by an MSRP Talker Declaration. It represents the maximum rate, in units of 1024 octets per second, at which frames in the Stream referenced by the Talker Declaration may be transmitted. |
TSpec Max Interval Frames |
The 32-bit unsigned Frame Rate component is used to allocate resources and adjust queue selection parameters in order to supply the quality of service requested by an MSRP Talker Declaration. It represents the maximum number of frames that the Talker may transmit in one second. |
