50.4 Command Summary: System-Wide Configuration

The following section lists the commands for this feature.

50.5 Command Examples: System-Wide

This example configures WFQ on the Switch and assigns weight values (1,2,3,4,12,13,14,15)
to the physical queues (Q0 to Q8).

This example configures the Switch to use WRR as a queueing method but configures the
Gigabit ports 9-12 to use SPQ for queues 5, 6 and 7.

COMMAND

DESCRIPTION

M

P

queue priority <0-7> level <0-7> Sets the IEEE 802.1p priority level-to-physical queue

mapping.
priority <0-7>: IEEE 802.1p defines up to eight separate

traffic types by inserting a tag into a MAC-layer frame that

contains bits to define class of service. Frames without an

explicit priority tag are given the default priority of the ingress

port.
level <0-7>: The Switch has up to 7 physical queues that

you can map to the 8 priority levels. On the Switch, traffic

assigned to higher index queues gets through faster while

traffic in lower index queues is dropped if the network is

congested.

Note: Some models only support 4 queues.

spq

Sets the Switch to use Strictly Priority Queuing (SPQ).

wrr

Sets the Switch to use Weighted Round Robin (WRR).

wfq

Sets the Switch to use Weighted Fair Queuing (WFQ).

fe-spq

Enables SPQ starting with the specified queue and

subsequent higher queues on the 10/100 Mbps ports.
