IP address conflict on Windows 7 clients after change 3560 to 3650

[Matthias Schmidt]

Hi,

after a switch change 3560 to 3650 some Windows 7 clients show a popup with the message "IP address conflict". Because of using manual DHCP (MAC reserve an IP address) i would exclude the possibilitiy of using an duplicate IP address. After search i found this document:

http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/8021x/116529-problemsolution-product-00.html

I tried the command 

ip device tracking probe delay 10

on the 3650 sw. Till now there are no messages with duplicate IP addresses on clients which connected to 3650 sw.

But on on 3560 sw th command does not exist. Anybody who has a similar problem or an idea to solve the problem on the 3560 sw.

The command "sh ip device tracking all" on 3560 shows that ip device tracking is disabled.

Thx for any help.

which IOS version are you running on the 3560?

Device tracking can also be disabled with the command " ip device tracking maximum 0" on the interfaces (I had to do it on a 4506)

IOS version 12.2.(46) SE

the suggested command does not exist.

btw the ip address conflict popup appears on clients which are connect to the 3560 too.

any other ideas?

ip device tracking maximum 0 on the 35650 interfaces is configured on 3560 interfaces the command doesn't exisist in the IOS version 12.2(46) SE.
