Enterasys Networks 5H1XX, 5G1XX manual Figure C-1 Class of Service Example

Properly configured, the Class of Service mechanism assures that during congestion, the highest priority data does not get delayed by normal priority traffic. The tagged header in the frame governs individual frame priority.

Figure C-1 shows priority queuing operating within a switch. Frames entering the switch through ports 1 and 4 are tagged as normal traffic and placed in a normal priority queue on the outbound port. Frames entering through ports 2 and 5 are tagged as high priority traffic and placed in a high priority queue on the outbound port. Priority queuing can be configured using the console interface or via SNMP.
