Invalid network mask

[ofca]

Is this reliably documented somewhere? How can I decide what is the correct netmask? How can I find the device that caused creation of 10.0.0.0/8 subnet with "correct" netmask of /8?

Hi,

server considers that first device found in certain subnet to be configured correctly (because usually it's a router). Sometimes it may encounter incorrectly configured device first. You can check all devices within subnet manually using "Interrfaces" tab, or you can create NXSL script that will walk nodes within subnet and report those with /8 mask on interface.

Best regards,

Is it wrong netmask definition from node?

Hi,

seems that agent read network mask incorrectly. I'll check it.

Can you please provide:

1. output of nxget command line tool, getting interface list. Example: /opt/netxms/bin/nxget -l 192.168.100.5 Net.InterfaceList
2. Agent version
3. OS version(where the agent is installed)

Thank you

Hi,

I probably found a bug. Please try this agent version: https://cloud.netxms.org/index.php/s/JOmIn3OAWql7oBT.
