Priority Settings

The ZT 8101 switch allows you to assign specific levels of priority to traffic traversing the switch. Setting priority allows you to protect bandwidth for important nodes on your network. Frames that match the user defined criteria are given a priority tag. The switch supports four hardware priority levels per egress port, so the eight levels (0-7) of priority are mapped to four hardware queues (0-3) as listed in the table below.

Priority in Frames	Priority Queue of ASIC
0-1	0
2-3	1
4-5	2
6-7	3

After an Ethernet frame has been prioritized, the switch forwards the Ethernet frame using the strict priority-based scheduling algorithm. With this algorithm, any frames residing in a higher priority queue are always transmitted first. Only when these queues are empty are frames in lower priority queues transmitted. If priority is not assigned to a frame the default value is 0.

Note: If flow control is enabled, a small of amount of low priority traffic may be forwarded before high priority traffic.

MAC Address Priority

You can specify a MAC address so that packets with this address are given special handling, either a higher or lower priority than normal traffic.

To set up a MAC address priority

1.In the left panel, click Priority Settings.

2.In the top panel, click MAC Address Priority.

3.Click New and configure these fields.
