enable diffserv examination ports

enable diffserv examination ports [port_list | all]


Enables the DiffServ field of an IP packet to be examined in order to select a QoS profile.

Syntax Description

port_list Specifies a list of ports or slots and ports to which the parameters apply.
all Specifies that DiffServ examination is enabled for all ports.



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.


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


This command was first available in ExtremeXOS 10.1.

Platform Availability

This command is available on all platforms.
