Configuring And Viewing Port-Based Priority - HP ProCurve 2810 Series Management And Configuration Manual

Trunked ports do not allow non-default (1 - 7) port-based priority settings.
■
If you configure a non-default port-based priority value on a port and then
add the port to a port trunk, then the port-based priority for that port is
returned to the default "0".

Configuring and Viewing Port-Based Priority

This command enables or disables port-based priority on a per-port basis. You
can either enter the command on the interface context level or include the
interface in the command.
Syntax: interface <port #> qos priority < 1 .. 7 >
Configures a non-default port-based 802.1p priority for
incoming, untagged packets or tagged packets arriving with
a "0" priority on the designated ports, as described under
"Operating Rules for Port-Based Priority", above.
interface <port #> qos priority 0
Returns a port-based priority setting to the default "0" for
untagged packets received on the designated port(s). In this
state the switch handles the untagged packets with "Normal"
priority. (Refer to table 10-3 on page 10-27.)
show running-config
Lists any non-default (1 - 7) port-based priority settings in
the running-config file on a per-port basis. If the priority is
set to the (default) "0", the setting is not included in the show
config listing.
show config
Lists any non-default (1 - 7) port-based priority settings in
the startup-config file on a per-port basis. If the priority is set
to the (default) "0", the setting is not included in the show
config listing.
For example, suppose you wanted to configure ports A10 -A12 on the switch
to prioritize all untagged, inbound VLAN traffic as "Low" (priority level = 1;
refer to table 10-3 on page 10-27).
