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:

Once the Priority List is defined, the Priority List can be assigned to a Remote Site interface

or the LAN interface.
