Qav Parameters
Use the Qav Parameters screen 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 screen, you can view and configure selected b
andwidth allocations
for Class A and Class B traffic.
 To configure the Qav parameters:
1. Select Switc
hing> MRP > Advanced > Qav Parameters.
2. Select the port
s to configure.
For information about how to select and configure one or more ports, see Configuring
Interface Settings on p
age 32.
3. Configu
re the Class A MSRP delta bandwidth.
Class A Delta bandwidth is the additional bandwidth represented as a percentage of port
transmit rate which can b
e reserved for the traffic class A and traffic class B. Class A
traffic has a higher priority. The range is 0–100.
4. Configu
re the Class B MSRP delta bandwidth.
Class B Delta bandwidth is the additional bandwidth represented as a percentage of port
transmit rate which can b
e reserved for the traffic class B. The range is 0–100.
5. Click the Appl
y button.
The following table provides information a
bout the status fields on the screen.
Table 73. Qav Parameter Status Information
Field Description
Bandwidth Allocated The current rate of the class A or B traffic on interface (in Bps).
Remaining Bandwidth The maximum rate of the class A or B traffic available on interface (in Bps)
Total Bandwidth Allocated The Sum of the allocated Class A and Class B traffic rates on interface (in Bps).
Total Remaining Bandwidth 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.
