Usage
Information
After you configure a unicast queue as strict-priority, that particular queue, on the entire chassis, is
treated as a strict-priority queue. Traffic for a strict priority is scheduled before any other
queues are serviced. For example, if you send 100% line rate traffic over the SP queue, it starves all other
queues on the ports on which this traffic is flowing.
Per-Port QoS Commands
Per-port QoS (port-based QoS) allows you to define the QoS configuration on a per-physical-port basis.
dot1p-priority
Assign a value to the IEEE 802.1p bits on the traffic this interface receives.
Syntax
dot1p-priority priority-value
To delete the IEEE 802.1p configuration on the interface, use the no dot1p-priority command.
Defaults none
