Chapter 12
IEEE 802.1p Priority Commands
This chapter explains IEEE 802.1p Priority CI Commands.
12.1 Introduction
IEEE 802.1p Priority CI Commands assign priority levels to individual 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.
12.2 IEEE 802.1p Priority Commands
Bridge port 1 stands for the Ethernet uplink port, bridge port 2 stands for DSL port 1, bridge port
3 stands for DSL port 2, and so on.
12.2.1 Priority Port Command
Syntax:
192.168.1.1 vlan1q> priority port <port #> <priority>
where
<port #> = Bridge port number. Valid parameter range = [1 - 25].
<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 that is assigned to untagged frames from a specified 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
12.2.2 Regen Port Command
Syntax:
192.168.1.1 vlan1q> regen port [<port #> <user priority> <regened
priority>]
where
<port #> = Bridge port number. Valid parameter range = [1 – 25].
<user priority> = The user priority for a frame received on this port. Valid parameter
range = [0 – 7 or *], where 0 is the lowest priority, 7 is the highest
priority and * means all user priorities.
