UNICOM Electric 8 - Manual (Page 44)

Priority Queue Service settings:
First Come First Service: The sequence of packets sent depends on
arrival order.
All High before Low: All high priority packets sent before low priority
packets.
Weighted Round Robin: Select the preference given to packets in the
switch’s high-priority queue.
These options represent the number of high priority packets sent before
one low priority packet is sent. For example, 2 High: 1 Low means that
the switch sends 2 high priority packets before sending 1 low priority
packet.
Enable Delay Bound: Limits the queuing time for low priority packets.
The default Maximum Delay Time is 255ms.
If the low priority packets stay in the switch over the Max Delay Time,
they will be sent. The valid time range is 1 ~ 255 ms.
NOTE: Max bridge transit delay bound control must be enabled before enabling
Delay Bound.
QoS Policy: High Priority Levels: 0 ~7 priority levels can map to high or
low queue. When a frame’s VLAN Tag number is mapping the priority
level of the port; this frame can have high priority. (This QoS Policy is for
the entire switch, not for a single port)
