enable dot1p examination ports [port_list | all]

Syntax Description

port_list Specifies a list of ports on which to enable the dot1p examination feature.
all Specifies that dot1p examination should be enabled for all ports.



Usage Guidelines

To increase available ACLs, you can disable the 802.1p examination feature if you are not running QoS or are running QoS using DiffServ. See the ExtremeXOS 32.2 User Guide for information on ACL limitations on these platforms.

Use this command to re-enable the 802.1p examination feature.

As part of the COS global status enable action, COS will automatically enable dot1p examination on all ports. An internal status will track this event. The disable dot1p examination command will print an additional warning message in the event that COS was configured via SNMP. If the COS global status is disabled via SNMP, the internal status will be cleared and the additional warning message will not be displayed.


The following command enables dot1p examination on ports 1 to 5:

enable dot1p examination ports 1-5
