Hello,

i have a lot of Aruba APs i want to monitor, problem on discovery:
only 1 is discovered:
log:

2023.08.08 16:57:42.286 *D* [poll.discovery    ] AcceptNewNode(10.66.180.129): IP address xxxxxxxxxxxon interface BR0 matches existing node xxxxxxxxxxxxx [1678]
2023.08.08 16:57:42.286 *D* [poll.discovery    ] AcceptNewNode(10.66.180.131): MAC address is not known, will lookup in ARP caches
2023.08.08 16:57:42.286 *D* [poll.discovery    ] AcceptNewNode(10.66.180.131): found MAC address 44:48:C1:C8:22:0A
2023.08.08 16:57:42.287 *D* [poll.discovery    ] AcceptNewNode(10.66.180.131): filter flags=0000

how can i avoid this problem ? The Aruba AP have all the same ip on BR0 interface...

Yes, NetXMS expects IP addresses to be unique within a zone. What probably should help - we can disable interface creation. In script library there is Hook::CreateInterface script, it is executed each time a new interface is found. Here's an example:

if ($node->snmpOID == ".X.X.X.X" and $1->name == "BR0") {
  PollerTrace("Blocking interface " .. $1->name .. " creation");
  return false;
}
return true;

I am checking node's SNMP ID, you can use any other approach - by subnet, container, etc - this is not to affect other nodes that might also happen to have an interface named BR0. PollerTrace line is optional - it's just for adding some info to output of manually-called configuration poll.
You have to delete all existing BR0 interfaces (or probably just one) that you have in your system.

Hello,

it works perfect!!

thank you
