The diagram below illustrates a pass-through configuration where packets are transmitted in the same order
as they are received.
The QoS feature introduced in VC 4.01 allows administrators to configure traffic queues for different priority
network traffic, categorize and prioritize ingress traffic and adjust DOT1P priority settings on egress traffic.
Administrators can use these settings to ensure that important traffic receives the highest priority handling
while less important traffic is handled at a lower priority.
The default QoS configuration in VC 4.01 is pass-through. Two other configuration types for "Custom (with
FCoE Lossless) (on page 105 )" and "Custom (without FCoE Lossless) (on page 108 )" provide administrators
with basic settings that can be further tuned depending on whether FCoE traffic is present in the Virtual
Connect environment.
