NetXMS Support Forum

I found a bit of a bug (I think)..
When some nodes change their IP address, rather than the address changing in NETXMS, some nodes get an extra network card showing, with the old IP address on one, and the new IP address on the other leading to false alarms about a down node, and false node up indicators. Both show the same MAC address in Netxms with different IP addresses. To clear them, I do a ping to the machine name to get the right IP address and then delete the incorrect interface in NETXMS. This happens whenever a node gets a new IP address.

Another related issue is that if I do not get a duplicate NET adapter, I get a duplicate NODE with the same name, but a new GUID, ID, and IP address.

Ideas?

Hi,

what are you using as primary host name (visible in properties on "Communications" page) - DNS name or IP address? I recommend to use DNS names for nodes with dynamic IP addresses. If they change often you may also want to set server's configuration parameter ResolveDNSToIPOnStatusPoll to 1 so server will resolve DNS names on each status poll (by default it is done only on configuration polls).

Best regards,
Victor
