Default Setting
Weighted Round Robin
Command Mode
Global Configuration
Command Usage
• Strict priority requires all traffic in a higher priority queue to be processed
before lower priority queues are serviced.
• WRR uses a relative weight for each queue which determines the number of
packets the switch transmits every time it services a queue before moving on
to the next queue. Thus, a queue weighted 8 will be allowed to transmit up to
8 packets, after which the next lower priority queue will be serviced according
to it’s weighting. 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 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
