Network diagram in HP Procurve Manager

[themightymrp]

Can anyone shed some light on this odd one?

 

We have HP Procurve switches throughout the school and I currently manage them via the HP Procurve Manager software. I have been re-organizing the layout / wiring structure in preperation for splitting up the network into VLANs. All is going very well so far.

 

I am using the feature that maps out a diagram of the network using the LLDP protocol and 99% has shown up correctly (found some really odd old wiring layouts that I've now been able to correct ) However, I have maybe 4 of the 1810-24G switches which arent creating the connection lines. I have plenty of others of the same model which DO show up. I have checked they are all running the same firmware, which they are (v2.2). LLDP is turned on via the web interface for all sockets. Why won't these 4 draw their links in?????? The LLDP --> remote device part of the web interface shows the correct switch that it uplinks to so it must be working?

 

Any clues???
