Duplicate IP address detected in WCS

Unanswered Question
Jul 1st, 2010

Hi to Cisco Support Community,

I would like to verify some questions regarding our network setup for wireless devices.

We have here in our client a 5508 WLC version and WCS version using windows platform.

My concern is that there is always a duplicate IP address detected by the WCS and when we trace the machine given its MAC address, we found out that the machine is a printer with a static IP of different IP address not the same to the management IP address of the WLC.

I have already disabled the port where the machine detected is terminated and still experiencing the same issue.

Is this a software bug or some sort of network issue? Please advice.

Thank you in advance!



I have this problem too.

Is the 5508 connected using two or more links?  If yes, is it confired as LAG in the 5508-side and etherchannel on the switch side?

No, it is only connected to one uplink to the 6500 catalyst core switch.

I have raised the issue with TAC and they told me that this is a software issue, we are currently making packet sniffs which is needed by the software developer. I will give you updates on this.
