QoS Support

Back to Top

In order for EdgeSwitch XP to classify and differentiate types of traffic when applying QoS rules, the traffic must have a special value set in the IP Header DSCP field. The originating software or hardware device is responsible for applying this value, and only if this field is set will traffic be prioritized.

By default, all traffic is classified as Best Effort, meaning there is no prioritization. The other categories can be defined with the following values:

802.1p Class of Service TOS Range DSCP Range WME Category
0 - Best Effort 0x00-0x1f 0-7 Best Effort
1 - Background 0x20-0x3f 8-15 Background
