3. Select the required Ingress Rate for this port.
The ingress rate (input data rate) limits the rate that traffic is passed into the port. Operators can
protect the terminal's traffic buffers against flooding by rate-limiting each port.
4. Select the Priority for all Ethernet data entering this port.
The priority specifies where the priority control information is sourced from.
From Frames
Traffic is prioritized into one of the following traffic types (numbered 0 to 7) by the originating device
or application. Generally, the higher the priority, the higher the priority rating.
However, in the IEEE standard queuing scheme, the ordering of the priority is 1, 2, 0, 3, 4, 5, 6, 7. In
this case 0 has a higher priority than 1 and 2.
If priority control information is present in the Ethernet header, this information is used to priorities
the traffic but if there is no priority control information in the Ethernet header, the IP header is used
to priorities the traffic.
Low, Medium, High, Very High
The priority rating you select is applied to all traffic on the port and is applied to all traffic
irrespective of traffic type and the priority control information in the traffic.
