NetXMS Support Forum

Greetings...

I recently replaced a Cisco switch and used the same IP address when configuring the new switch.  The new switch is working as expected, but NetXMS will not recognize the new device.  Before adding the new switch I deleted the old node and then I tried to create a new node with the same IP, but I get an IP conflict error (see attached screenshot). 

The log file indicates an object as a "lost_node" which I'm sure is the new switch.

Any thoughts on how to resolve this would be greatly appreciated!

Thanks in advance!

Hi,

likely old node was not deleted completely. Try to login with user "system", find that node, and delete it.

Best regards,

That fixed it, thanks Victor!
