Action – Defines traffic management where packet forwarding is based on packet information
and packet field values such as VLAN Priority Tag (VPT) and DiffServ Code Point (DSCP).
After packets are assigned to a specific egress queue, CoS services can be assigned to the queue.
Egress queues are configured with a scheduling scheme by one of the following methods:
•
Strict Priority – Ensures that time-sensitive applications are always forwarded. Strict Priority
(SP) allows the prioritization of mission-critical, time-sensitive traffic over less time-sensitive
applications.
For example, under SP, voice over IP (VoIP) traffic can be prioritized so that it is forwarded before
FTP or email (SMTP) traffic.
•
Weighted Round Robin – Ensures that a single application does not dominate the device
forwarding capacity. Weighted Round Robin (WRR) forwards entire queues in a round robin
order. If WRR is selected, the following weights are assigned to the queues: 1, 2, 4, 8.

Defining General QoS Settings
The CoS Page contains information for enabling QoS globally and on specific interfaces. After
QoS has been configured, the original device QoS default settings can be reassigned to the
interface in the CoS Page.
