Assigning a priority for a global source-port classifier
This global QoS packet-marking option assigns a priority to all outbound packets having the specified source-port.
This option can be configured by either specifying the source-port ahead of the
qos
command or moving to the port context for the port you want to configure for priority. For configuring multiple source-ports with the same priority, it is easier to use the
interface
port-list
command to go to the port context instead of individually configuring the priority for each port.
Syntax:
interface port-list qos priority 0 - 7
Configures an 802.1p priority for packets entering the switch through the specified (source) ports. This priority determines the packet queue in the outbound ports to which traffic is sent. If a packet leaves the switch on a tagged port, it carries the 802.1p priority with it to the next downstream device. You can configure one QoS classifier for each source-port or group of source-ports.
Default: No-override
Syntax:
no interface port-list
Disables use of the specified source-ports for QoS classifiers and resets the priority for the specified source-ports to
No-override
.
Syntax:
show qos port-priority
Lists the QoS port-priority classifiers with their priority data.
