Example 
The following example sets the queue mode to strict priority service mode:

This command sets a priority for incoming untagged frames. Use the no 
form to restore the default value.

switchport priority default default-priority-id
no switchport priority default

default-priority-id - The priority number for untagged ingress traffic. 
The priority is a number from 0 to 7. Seven is the highest priority. 

The priority is not set, and the default value for untagged frames 
received on the interface is zero.

Interface Configuration (Ethernet, Port Channel)

• The precedence for priority mapping is IP Port, IP Precedence or IP 

DSCP, and default switchport priority. 

• The default priority applies for an untagged frame received on a port 

set to accept all frame types (i.e, receives both untagged and tagged 
frames). This priority does not apply to IEEE 802.1Q VLAN tagged 
frames. If the incoming frame is an IEEE 802.1Q VLAN tagged 
frame, the IEEE 802.1p User Priority bits will be used. 

• This switch provides eight priority queues for each port. It is 

configured to use Weighted Round Robin, which can be viewed with 
the show queue bandwidth command. Inbound frames that do not 
have VLAN tags are tagged with the input port’s default ingress user 
priority, and then placed in the appropriate priority queue at the 
output port. The default priority for all ingress ports is zero.
