Hello, friend!
The traffic-priority command is used to configure the priority of the packets that match certain ACLs on a specified port. To schedule the traffic of a specified portbased on the priority carried in the traffic, run this command. After the priority is set successfully, the port forwards the packets that match the ACL rules based on priority to ensure various QoS.
Usage Guidelines
Boards providing Ethernet ports, P2P boards, and control boards support this command.
By default, the priority of the packets of the port is not configured.
Only the "permit" rule (configured by running the rule command) can be used when you run the command to filter the packets. If you use the "deny" rule, the command does not take effect.
After an ACL rule is configured on a port by running the traffic-priority command, in the case of a service port, the ACL rule takes effect to all other service ports on the same service board; in the case of an upstream port, the ACL rule takes effect to only the upstream port itself.
The DSCP priority and IP priority cannot be set at the same time.
When you need to change the action that already takes effect on a specified port, you must delete the original action and then issue the new action.
Users do not need to configure acl-index when deleting QoS actions because the system deletes QoS actions based on ACL rules.
You can run the display current-configuration section post-system | include traffic-priority command to query the configuration result.
Thanks!
