3400cl DHCP issues? Random broadcast issues

[DBrown_1]

Hey all, I have 3 3400CL-48port switches in a test environment that I seem to have a problem with. One of the switches (SW03) is not supplying DHCP addresses to any device that is conencted to it. It also seems to be a little spotty on packet transfers.

I do know when this environment was setup (before I was here) that they cabled the switches wrong. Instead of Switch1 (SW01) going to SW02 and SW02 going to SW03, it appears that SW01 is cabled to both SW02 and SW03 directly. The three switches are 'stacked' together.

SW01 and SW02 I seem to have no problems with at all. All 3 switched are firmware 10.41 -- Any help is much appreciated!
