Optimizing Traffic Flow with Port Controls, Port Trunking, and Port-Based Priority
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: 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.
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 9-8 on page 9-35.)
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 prior-
ity 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 9-8 on page 9-35).
