The following table describes the fields on the MSRP Stream Information screen.

Table 74.  MSRP Streams Information 

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  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.

Traffic Class 

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 (e.g. network reconfiguration, 802.11 bandwidth reduction) 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.

TSpec Max Frame Size 

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.

Stream VLAN 

The VLAN ID of the traffic stream.

Destination MAC 

The MAC address of the traffic stream’s destination.

Received Failure Bridge 
Interface 

The interface on the Bridge where the failure occurred.

Received Failure Code 

The code value of the failure. For more information about the failure codes, see 

Failure Code 

on page 199.

Received Failure Bridge MAC  The MAC address of the switch where the failure occurred.

Talker Interface 

The interface on which the Talker is present.

Listeners 

The interface on which Listeners are present.
