weight1...weight4 - The ratio of weights for queues 0-3 determines the weights
used by the WRR scheduler. However, note that Queue 0 is fixed at a weight of
1, and cannot be configured. (Range: 1-31)

Default Setting

Weights 1, 2, 4, 6 are assigned to queues 0-3 respectively.
Queue 0 is non-configurable.

Command Mode

Global Configuration

Command Usage

WRR controls bandwidth sharing at the egress port by defining scheduling
weights.

Example
This example shows how to assign WRR weights to priority queues 1 - 3:

Related Commands
show queue bandwidth (4-168)
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 Prioritybits
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.
