wait before being allowed to transmit its accumulated packets.
This establishes a Class of Service (CoS) for each of the switch's
four hardware priority queues.
The possible range for maximum packets is: 0 to 255 packets.
The possible range for maximum latency is: 0 to 255 (in
increments of 16 microseconds each).
Remember that the DES-3250TG has four priority queues (and
thus four Classes of Service) for each port on the switch.

The Max. Packets(O-255) field specifies the number of packets
that a queue will transmit before surrendering the transmit
buffer to the next lower priority queue in a round-robin
fashion.
The Max. Latency(0-255) field specifies the maximum amount
of time that a queue will have to wait before being given access
to the transmit buffer. The Max. Latency(0-255) is a priority
