[Al_Mat]

Hello!

I have many ARP-1038 error on VDX6740 comming from our Aruba Controller. I noticed that errors appears at the end of DHCP lease time and it's not for all IP.



it's a lot of errors like that:

2018/03/07-06:09:45, [ARP-1038], 78455, SW/0 | Active | DCE, WARNING, VDX6740-1, Duplicate IP 172.16.32.82 detected. New MAC-Address 5cf5.da95.6ce3, Old MAC-Address 8410.0d9a.aef9.



Is anyone could help me?



Thanks

This does not look like a VDX issue at all. This above looks like a DHCP server lease problem and/or duplicate DHCP servers, wrong DHCP relay or just duplicated IP configurations. Above you see an issue between a Macbook and a Lenovo laptop.
