I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

At first I would recommend to get the latest firmware for the switch, e. g. 12.1.22-EA8a. You should get it on the Cisco web site when you have a CCO login or from your local reseller. Then have a look at this:

Thanks for your help.

I loaded the example image and the switch seems to boot in a loop. I then loaded c2950-i6q4l2-mz.121-6.EA2c and now it is running great. Thanks again.
