Version Description
6.1.1.1 Introduced on the E-Series.
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.
