Example
The following example sets the queue mode to strict priority service mode.
switchport priority default
This command sets a priority for incoming untagged frames. Use the no
form to restore the default value.
Syntax
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.
Default Setting
The priority is not set, and the default value for untagged frames
received on the interface is zero.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• The precedence for priority mapping is 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.
