IEEE 802.1p Priority Commands

This chapter explains IEEE 802.1p Priority CI Commands.

9.1Introduction

IEEE 802.1p Priority CI Commands provide priority regeneration for ports. IEEE 802.1p defines up to eight priorities (0-7) by inserting a tag into a MAC-layer frame that contains bits to define priority of service.

9.2IEEE 802.1p Priority Commands

Bridge port 1 stands for the Ethernet port, bridge port 2 stands for ADSL port 1, bridge port 3 stands for

ADSL port 2, and so on.

9.2.1Priority Port Command

Syntax:

192.168.1.1 vlan1q> priority port <port #> <priority>

where

 

 

<port #> =

 

bridge port number. Valid parameter range = [1 - 9].

<priority>

=

default priority for the specified port. Valid parameter range = [0 - 7], where 0 is

 

 

the lowest priority and 7 is the highest priority.

This command sets the default priority for an ingress port.

To display the default port priority table, simply use the Priority Port command without parameters, as shown next.

192.168.1.1 vlan1q> priority port

9.2.2Regen Port Command

Syntax:

192.168.1.1 vlan1q> regen port [<port #> <user priority> <regened priority>]

where

 

 

 

<port #>

=

bridge port number. Valid parameter range = [1 – 9].

<user priority>

=

the user priority for a frame received on this port. Valid parameter

 

 

range = [0 - 7], where 0 is the lowest priority and 7 is the highest

 

 

priority.

<regened priority> =

the regenerated user priority the incoming user priority is mapped to for

 

 

<port #>. Valid parameter range = [0 - 7], where 0 is the lowest

 

 

priority and 7 is the highest priority.
