• 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. Therefore, any inbound
frames that do not have priority tags will be placed in queue 0 of the
output port. (Note that if the output port is an untagged member of the
associated VLAN, these frames are stripped of all VLAN tags prior to
transmission.)
Example
The following example shows how to set a default priority on port 3 to 5:
queue bandwidth
This command assigns weighted round-robin (WRR) weights to the eight
class of service (CoS) priority queues. Use the no form to restore the default
weights.
Syntax
queue bandwidth weight1...weight4
no queue bandwidth
weight1...weight4 - The ratio of weights for queues 0 - 7 determines the
weights used by the WRR scheduler. (Range: 1 - 15)
Default Setting
Weights 1, 2, 4, 6, 8, 10, 12, 14 are assigned to queues 0 - 7 respectively.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
WRR controls bandwidth sharing at the egress port by defining
scheduling weights.
Console(config)#interface ethernet 1/3
Console(config-if)#switchport priority default 5
