When video packets are being dropped, and the network is configured to use the expedited-forwarding forwarding class, it typically indicates that the scheduler assigned to this class does not have sufficient bandwidth to handle the traffic. Adjusting the scheduler to allocate more bandwidth to the expedited-forwarding class will ensure that video packets are transmitted without being dropped.
Steps:
* Identify the scheduler map: First, identify the scheduler map that is applied to the interfaces. This can be done using the following command:
shell
Copy code
show configuration class-of-service scheduler-maps
* Adjust the scheduler: Modify the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate. You can edit the scheduler configuration to increase the bandwidth allocated.
Example:
shell
Copy code
set class-of-service schedulers expedited-forwarding transmit-rate percent 30
* Apply the configuration: Apply the modified scheduler to the interfaces using the following commands:
shell
Copy code
set class-of-service interfaces ge-0/0/0 scheduler-map <scheduler-map-name> set class-of-service interfaces ge-0/0/1 scheduler-map <scheduler-map-name> commit References:
