Qav parameter status information (continued) Field Total Bandwidth Allocated Total Remaining Bandwidth Description The Sum of the allocated Class A and Class B traffic rates on interface (in Bps). 75% of the interface speed minus total allocated bandwidth (in Bps/sec). MSRP Streams Information Use the MSRP Stream Information screen to view information about MSRP streams flowing through each interface. To view MSRP Stream Information screen, select Switching > MRP > Advanced > MSRP Stream Information. The following table describes the fields on the MSRP Stream Information screen. Table 46. MSRP streams information 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 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. Configuring Switching 140

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
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.
