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.

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.
