I have an 8 3750G switch stack that does IP intervlan routing for 20 different vlans.
The top 2 switches have all servers conencted to them. Bottom 6 switches are client access switches. All switches provide gigabit connections to servers and clients.
I verified that the stack ring is running at full duplex 32 gbps.
Seems like top switch is performing very slowly when tranfering data between servers, speeds of < 100 megabit.
All ports are set to auto/auto as well as the servers and clients.
No errors on the ports whatsoever.
I'm guessing that there may be some over subscription but I do not know what to look for.
Can anyone guide me in the way to see what can be causing the crappy performance?
Should I seperate the IP routing switches from the access switches?
