Weird CDP problem on 3550G-24PWR-SMI

I was wondering if anyone else ever ran into this problem. I have 3 AS2509's configured on my network. When I go to install a Catalyst 3550 on the network I get a CDP-4-DUPLEX_MISMATCH error message on the 3550 with the Ethernet ports on the 2509's. Any reason why this would be happening?

Re: Weird CDP problem on 3550G-24PWR-SMI

what software version are you running on the 3550? What is the flowcontrol setting on the 3550? Take a look at the following bug

I'm using the following image file: c3550-i9q3l2-mz.121-12c.EA1

The flowcontrol is just set to auto (on fa 0/1)

Thanks.
