QOS - Priority Queuing
Priority Queuing (PQ) allows the users to configure the router to allow
specific traffic bound for an outgoing interface to be prioritized into
high, medium, normal and low queues. Packets sent to the high priority
queue are serviced first, followed by the packets on the medium queue
and so on. The router can configure outbound traffic to specific queues
based upon protocol, addresses and incoming interfaces.
To enable Priority Queuing you must configure a Priority list which
contains the criteria items for the outbound packets. Each packet will
be compared to item #1 in the Priority List and then progress down
the list of items in order until a match is found. When a match is
found, the comparison search will stop and the packet will be given the
priority configured for that item. Thus more specific priority criteria
should be defined at the beginning of the list.
To define item criteria within a Priority List:
