disable dot1p examination ports

disable dot1p examination ports [port_list | all]

Description

Prevents examination of the 802.1p priority field as part of the QoS configuration.

Syntax Description

port_list Specifies a list of ports or slots and ports.
all Specifies that dot1p replacement should be disabled for all ports.

Default

Enabled.

Usage Guidelines

The 802.1p examination feature is enabled by default. To free ACL resources, disable this feature whenever another QoS traffic grouping is configured. (For information on available ACL resources, see ACLs in the ExtremeXOS 32.1 User Guide )

Note

Note

If you disable this feature when no other QoS traffic grouping is in effect, 802.1p priority enforcement of 802.1q tagged packets continues.

SummitStack Only.

Dot1p examination cannot be disabled for priority values 5 and 6. However, the precedence of the examination is lowered so that all other traffic grouping precedences are higher. The mappings you configure with the configure dot1p type command remain in effect.

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.

Example

The following command disables 802.1p value examination on ports 1 to 5:

disable dot1p examination ports 1-5
