for all queues does not have to equal 100.
Scheduler Type. Select the type of queue processing. Options are Weighted and
Strict. Defining on a per-queue basis enables you to create the desired service
characteristics for different types of traffic. Four queues can be configured as strict
priority or WRR priority. If a specific queue is configured as WRR, all the queues with
a lower number are also WRR queues. The configuration is global and not per port.
Weighted. Weighted round robin associates a weight to each queue. This
association is the default.
Strict. Services traffic with the highest priority on a queue first.
Queue Management Type. Displays the type of packet management used for all
packets, which is Taildrop. All packets on a queue are safe until congestion occurs. At
this point, any additional packets queued are dropped.

2. Select the queue to which predefined 802.1p priority values are mapped.
The queue values represent traffic classes. The traffic class is the hardware queue for a
port. Higher traffic class values indicate a higher queue position. Before traffic in a lower
queue is sent, it must wait for traffic in higher queues to be sent.
