Poor 4503 switching performance!

Our Catalyst 4503 switches are performing shockingly. When just plug in PC's and ftp'd a 4mb file it had a tranfer rate of 100k a second!!!!!! Not good!!!

When we done the same test on a 3550 it was a astounding 4.2 mb!!!!! BIG difference.

Anyone got any ideas????

Duplex mismatch, perhaps?

Re: Poor 4503 switching performance!

Please not that depending on your switch SP engine and any modules, the bandwidth for a module is divided to a group of ports, for example ports 1,2,3,4, share the same bus, ports 5,6,7,8 share another bus, they are refered to as a blocking and non-blocking ports. You can provide us with little more detail about your switch.

If I were you and I'm in a hurry, I would first try to connect the FTP server's subnet directly to the SP engine, the ports on it are for sure non-blocking.

I think you should monitor the CPU and Memory utilization first.
