Create QoS Class elements

QoS Classes are used to collect QoS statistics about traffic or to create a link between the Access rules and the QoS Policy.

When traffic matches an Access rule, the QoS Class defined in the rule is applied to the traffic. QoS Classes can also be used in Outbound Multi-Link elements to adjust the load balancing of different types of connections.

You must create one QoS Class for each rule you plan to add in any single QoS Policy, as the QoS Policy cannot contain any overlapping rules. You can create as many QoS Classes as necessary. The QoS Policy must not have overlapping rules. You must create one QoS Class for each rule you plan to add to the QoS Policy (each type of traffic must have its own QoS Class). The same QoS Class can be used in multiple Access rules, so several Access rules can point matching traffic to the same QoS rule.

There is a default QoS Policy and three default QoS Classes. The classes can be used to set priorities for high, normal, and low priority traffic, without any bandwidth guarantees or limits.
