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.

Table 106 Queueing Command Summary

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.

C13

spq Sets the Switch to use Strictly Priority Queuing (SPQ). C 13

wrr Sets the Switch to use Weighted Round Robin (WRR). C 13

wfq Sets the Switch to use Weighted Fair Queuing (WFQ). C 13

fe-spq <q0|q1| ... |q7> Enables SPQ starting with the specified queue and

subsequent higher queues on the 10/100 Mbps ports.
