<![CDATA[Layer2 topology not working as expected]]>Can someone shed some light on this. The layer2 topology maps seem to vary wildly depending on which device I choose to create the map from
I.e. if I right click on Sw4 and choose Layer 2 Topology it will show ONLY show Sw4
If I do it with Sw5 it will show Sw5, Sw4, Sw7
If I do it with Sw7 it will show every switch
This is really strange because all switches are on the same VLAN, all have LLDP enabled. And if I look at the MAC database of any switch it shows everything correctly

I need to make detailed L2 maps but I get different results depending on which switch I choose. This is a big problem for me because it makes L2 maps very unreliable and that is one of the most important things for me at the moment. Am I doing something wrong? Have tried poll->topology and it doesn't seem to make much of a difference
Is there a way for NetXMS to make a map using lots of switches as a seed and then combine the results into 1 map?

Once you create a Layer 2 map, you can enter the map's properties and add more seed nodes (at least in 2.1 you can, I don't recall if that's a new feature or not).
You can also configure a custom discovery radius for the map.

Cheers
