D-Link DES-3250TG Standalone Layer 2 Switch (QOS Output) Scheduling Click QoS on the Configuration menu, and then click scheduling: Figure 6- 35. QoS Output Scheduling window 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 queue timer. When it expires, it overrides the round-robin and gives the priority queue that it was set for access to the transmit buffer. There is a small amount of additional latency introduced because the priority queue that is transmitting at the time the Max. Latency(0-255) time expires will finish transmitting its current packet before giving up the transmit buffer. Traffic Segmentation This window allows you to manage traffic segmentation on the switch.

(QOS Output) Scheduling
Click QoS on the Configuration menu, and then click scheduling:
Figure 6- 35.
QoS Output Scheduling window
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 queue timer.
When it expires, it overrides the round-robin and gives the priority queue that it was set for access to
the transmit buffer.
There is a small amount of additional latency introduced because the priority queue that is transmitting
at the time the Max. Latency(0-255) time expires will finish transmitting its current packet before giving
up the transmit buffer.
