Error Message

%IP-4-DUPADDR : Duplicate address [int] on [chars], sourced by [sci_notation]

Explanation Another system is using your IP address.

Recommended Action Change the IP address of one of the two systems.


Check to see if you have another network devices with the same mac address.

I hope this helps.

Best regards.

Is there any DHCP configured ?

If so you may need to check the settings and reduce the lease time


Hope this helps
