Usage Information
After you configure a unicast queue as strict-priority, that particular queue, on the entire chassis, is treated as a
strict-priority unicast. 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.
