If you are using your 5520 fo r big file trans fers (like backup of servers)
If you are using (the AppleTalk Filing Protocol) AFP, use large or maximum resource sharing
(AFP use a fix windows size set to 65,535K).You should use the large resource sharing setting:
If you are using your 5520 for high bandwidth application such as video.
If you are using large TCP windows for your traffic, use large resource sharing (you can also
reduce the TCP windows size on windows operating system - see Microsoft TechNet article
224829).
If you have 4 or fewer ports connected per group of 12 ports.
You should use the Regular resource sharing setting:
If you are using your 5520 in a VOIP environment.
If you have 5 or more ports connected per group of 12 ports.
Egress CoS Queuing
The following charts describe each possible egress CoS queuing setting. The mapping of 802. 1p priority
to egress CoS queue, dequeuing algorit hm, and queue weight is given. Additionally, the memory and
maximum number of packets which can be buffered per egress CoS queue and resource sharing settings
is shown.
