<DIV dir=ltr><FONT face=Arial color=#000000 size=2>I would mark your traffic
like you say, of course have priority for voice and set the rest of the classes
by Cisco docs when it comes to control traffic and video. The rest like
SMTP, SQL, telnet, etc.. you will have to determine that. Then just make
sure you have the proper queuing depths configured on your egress and
ingress.</FONT></DIV>
