Port Priority
Typically, networks operate on a best-effort delivery basis, which means that all traffic has
equal priority and an equal chance of being delivered in a timely manner. When congestion
occurs, all traffic has an equal chance of being dropped.
Using Port Priority feature, you can select specific network traffic, and prioritize it according to
its relative importance. Implementing Port Priority in your network makes network
performance more predictable and bandwidth utilization more effective.
