qos priority
Argument Description
priority
The 802.1p priority level in range <0-7>.
Example
The following example assigns the 802.1p priority levels for all incoming packets on interface
1/1/1. The
show qos priority-txq-map
command specifying the interface number verifies the
configuration.
device-name
(config)#
interface 1/1/1
device-name
(config-if 1/1/1)#
qos priority 3
device-name
(config-if 1/1/1)#
exit
device-name
(config)#
exit

#
show qos priority 1/1/1

Setting the Destination MAC Address Priority
The
qos mac
command, in Global Configuration mode, assigns QoS priority level manually per
destination MAC address (per VLAN). The
no
form of the command deletes the MAC address
priority assignment (the address itself is not deleted).
All traffic destined for a specific MAC address, per VLAN and per port, can be assigned a priority
level. The frame is then forwarded to a transmit queue using the mapping of 802.1p to transmit
queues.
To view the priority assignment for the MAC addresses, use the
show mac-address-table
command in Privileged (Enable) mode.
To clear the MAC addresses with the priority assignment the user can also use the
clear mac-
address-table
command in Privileged (Enable) mode and the
no mac-address-table
command in
Global Configuration mode.
By default, the MAC address priority is 0.
