Figure 7 - 29. QoS Class of Traffic window
Once you have assigned a maximum number of packets and a maximum latency to a given Class of Service on the switch, you can
then assign this Class to each of the eight levels of 802.1p priorities.
Scheduling
Click QoS on the Configuration menu, and then click scheduling :
Figure 7 - 30. 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.
Click Traffic Segmentation in the QoS folder on the Configuration menu:
