TitleHow to change the bandwidth for AVB?
AVB is using MSRP(Multiple Stream Reservation Protocol).This technology ensures audio and video can leverage a predefined amount of the bandwidth for AVB audio. This amount is 75% of the maximum data rate; the other 25% of bandwidth can be used for other data. How could we change the percentage of bandwidth for AVB?
  • Summit
  • EXOS 
Below is the command of how to configure the bandwidth for AVB switch on EXOS.

# configure msrp ports [port_list | all] traffic-class [A | B] delta-bandwidth percentage

The delta bandwidth configuration limits the amount of bandwidth that can be used by the given stream reservation class. Each class is allowed to use a maximum of its delta bandwidth plus the delta bandwidth configured for each of the higher classes. For example, if the delta bandwidth for classes A and B are configured to 10 and 10 respectively, class A streams can use up to 10 percent of the link bandwidth, and class B streams can us up to 20 percent of the link bandwidth. The sum of the class A and B delta bandwidth values must be less than 100 percent.


configure msrp ports all traffic-class A delta-bandwidth 50
configure msrp ports 1-5 traffic-lass B delta-bandwidth 0


Additional notes
This command is available on Summit X450-G2, X460-G2, and X670-G2 switches if the AVB feature pack license is installed on the switch.
