QoS overview
NOTE
You need to enter the copy running-config startup-config command to save your configuration
changes to NVRAM so that they are not lost if there is a system reload or power outage.
Quality of Service (QoS) provides you with the capability to control how the traffic is moved from
switch-to-switch. In a network that has different types of traffic with different needs (CoS), the goal
of QoS is to provide each traffic type with a virtual pipe. FCoE uses traffic class mapping,
scheduling, and flow control to provide quality of service.
Traffic running through the switches can be classified as either multicast traffic or unicast traffic.
Multicast traffic has a single source but multiple destinations. Unicast traffic has a single source
with a single destination. With all this traffic going through ingress (incoming) and egress (outgoing)
ports, QoS can be set based on egress port and priority level of the CoS.
QoS can also be set on interfaces where the end-station knows how to mark traffic with QoS and it
lies with the same trusted interfaces. An untrusted interface is when the end-station is not
intelligent and is at the administrative boundaries.
The QoS features are:
• Rewriting
Rewriting or marking a packet allows for overriding header fields such as priority and VLAN ID.
• Queueing
Queueing provides temporary storage for packets while waiting for transmission. Queues are
selected based on egress port and configured user priority level.
