Duplicate Endpoint IP address

Francisco_Aguil — Thu, 22 Dec 2022 18:50:21 GMT

I am currently in the task of detecting the duplication of IPs in endpoints (Laptops) in a CORE X670 and being able to alert the XMC through SNMP, however I have not been able to detect it through "ip-security arp gratuitous-protection" or through "DAD", Has anyone had this requirement and how did they solve it?

Maybe the easiest way is to implement the nac und sort for ips and scroll through all ips to see a duplicate....

or just configure elrp on the edge switches...

maybe there is a pyhton task solution but thats something i am not used too

If you mistakenly assign the same static address to two devices, you'll run into a duplicate IP error. This problem can also arise if you set a device to use a static IP without reserving that address in your router. Eventually, your router will try to hand out that address to another device, creating an IP conflict.
