<![CDATA[L2 topology - LLDP gives NO links]]>Hi,
I'm having a huge problem using the L2 topology - which is a great feature.
my devices use lldp - see attached info but nothing is draw in the L2 map (i have the devices without the lldp links).
what do I miss?
is it a bug?
centos \ netxms 3.0.2258.

as you can see I've attached both netxms and device data.
