Figure 6 - 91. QOS Class of Traffic
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 8 levels of 802.1p
priorities.
QOS Configuring Priority
The DES-3326SRSR allows you to configure how forwarded
packet's priority value will be changed or maintained by the
switch prior to transmitting the packet. You can specify how a
packet's priority value will be written by the switch by DSCP,
802.1p, TCP or UDP port number, IP address, or MAC address.
