The problem I am facing is that whenever there is high latency or packet loss on a particular link, all the PC on to that link create problem such like slow access to resources over WAN. I wanna change the sessions over other link. How to chk how much sessions are on a particular link

Hi

Well you could ip accounting although this will only show source and destination address and bytes transmitted not the port numbers so it won't give you session detail as such but it will give you client/server IP address and how much data is being transmitted.

Be aware there is obviously an overhead on the router by turning this on so you need to be careful.

As Martin said, the only way to make one session go over a specific link is to use PBR but this is not really what you want to be doing.
