802.1P Priority Table - ZyXEL Communications MES-2110 Support Notes

MANAGED 8-PORT 10/100 + 2 G DUAL PERSONALITY SWITCH
this list. The next queue is given an equal amount of bandwidth, and then moves to the
end of the list, and so on so forth. This works in a looping fashion until a queue is empty.
Weighted Round Robin Scheduling (WRR) uses the same alhorithm as round robin
scheduling, but the services queues are based on their priority rather than a fixed
amount of bandwidth. WRR is activated only when a port has more traffic than it can
handle. Queues with larger weights get more service than queues with smaller weights.
This queuing mechanism is highly efficient in that it divides any available bandwidth
across the different traffic queues and returns to queues that have not yet emptied.

802.1P Priority Table

The port priority (0~7) can be set in this screen.
Description
Select "all high before low" mode or "weighted round robin" mode. All
high before low queues are based on priority only, while weighted
round robin scheduling services queues on a rotating basis.
Port Priority uses port priority as queuing basis. Assign a priority
level to each port in the port priority screen.
Tag Priority uses VLAN tag priority as the basis.
IP ToS Priority uses IP DSCP priority as queuing basis.
IP & Tag Priority uses both IP DSCP priority and tag priority as
queuing basis.
See more details regarding the mode in the following section,
After you enable this feature and the Switch receives a frame containing
both IP DSCP and tag priority information, the Switch will only use the
IP DSCP priority information.
