Model: ER7206 (TL-ER7206)  
Hardware Version: V2
Firmware Version: 2.0.1 Build 20230705 Rel.75930

[osg:Router MAC] detected ARP conflict and dropped 2 packets. (Packet=192.168.1.215:98-03-CF-86-22-0A, Bind-Rule=192.168.1.215:00-14-41-80-05-D0)

Is clear an issue but there is only a MAC in the network : 00-14-41-80-05-D0

The other MAC is not existing in the network...

What should I cgeck to fix as the message is issued almost each 6 seconds, continously...

IP-MAC binding? DHCP scopes? Fixed IP addresses?

  @KJK IP-MAC binding, yes, with fixed IPs. Found the issue: wrong binding between IP and MAC. First unbind, then refresh ARP list, bind new IP to MAC and the later maybe change IP.

Thanks for good question!

Hi @CCDan 

Thanks for posting in our business forum.

So it is resolved?

KJK basically pointed you in the right direction in troubleshooting and finding a solution. Duplicate IP makes ARP warnings.
