of service time the switch services each queue before moving on to the
next queue. This prevents the head-of-line blocking that can occur with
strict priority queuing.
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 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.
