enable dot1p replacement ports

enable dot1p replacement ports [port_list | all] {{qosprofile} qosprofile}


Allows the 802.1p priority field to be overwritten on egress according to the QoS profile to 802.1p priority mapping for a given set of ports.

Syntax Description

port_list Specifies a list of ports or slots and ports.
all Specifies that dot1p replacement should be enabled for all ports.
qosprofile Enables dot1p on a QoS profile.
qosprofile Specifies the QoS profile number.



Usage Guidelines

The dot1p replacement feature is disabled by default.

By default, 802.1p priority information is not replaced or manipulated, and the information observed on ingress is preserved when transmitting the packet.



The port in this command is the ingress port.

If 802.1p replacement is enabled, the 802.1p priority information that is transmitted is determined by the hardware queue that is used when transmitting the packet.



This command affects only that traffic in traffic groupings based on explicit packet class of service information and physical/logical configuration.

Beginning with ExtremeXOS version 11.4 on the 1 Gigabit Ethernet ports, 802.1p replacement always happens when you configure the DiffServ traffic grouping.



Enabling dot1p replacement on all ports may take some time to complete.


The following example enables dot1p replacement on all ports:

enable dot1p replacement ports all


This command was available in ExtremeXOS 11.0.

The qosprofile keyword and qosprofile variable were added in ExtremeXOS 16.1.
