Good morning.
-----------------------------------------------------------------------
The message:
HPE iMC says "Duplicate devices are found. The IP addresses are "10.1.2.255,10.1.2.54", which are assigned to the same device"
---------------------------------------------------------------------
I have a network with 130 switches (controlled on a dedicated vlan), and since using Aruba Instant On 1930 switches, alarms started indicating that there is a switch with a duplicate IP in the switch network.
The problem appears with all Aruba Instant On 1930 switches (12 units)
Obviously, the IP address is unique and not duplicated. The devices are in the correct vlan.
The problem they generate is that the broadcast ip (x.x.x.255) takes the identity of 1 switch with the duplicate IP problem.
I think the problem originates from a port taking the IP "169.254.0.1/255.255.255.0" "User Definet Port 1" recognized as APIPA. I can't configure that IP/interface.
I did many tests without good results.
Does anybody have any suggestions?
Thank you very much in advance
