Class of Service Configuration
Class of Service (CoS) allows you to specify which data packets have greater
precedence when traffic is buffered in the switch due to congestion. This switch
supports CoS with four priority queues for each port. Data packets in a port’s
ty queue will be transmitted before those in the lower-priority queues.
You can set the default priority for each interface, and configure the mapping of
frame priority tags to the switch’s priority queues.

• Default Priority* – The priority that is assigned to untagged frames received on
the specified interface. (Range: 0-7, Default: 0)
• Number of Egress Traffic Classes – The number of queue buffers provided for
each port.
