Usage Guidelines

The Diffserv examination feature is disabled by default.

If you are using DiffServ for QoS parameters, we recommend that you also configure 802.1p or port-based QoS parameters to ensure that high-priority traffic is not dropped prior to reaching the MSM/MM on modular switches.

Example

The following command enables DiffServ examination on selected ports:
enable diffserv examination ports 1:1,5:5,6:2
