Title: Nedi 1.6 and Cisco AccessPoint 1800 series and 2800 series
Post by: swepart on February 14, 2018, 02:54:40 pm

Nedi 1.6

We have installed some new controllerbased Cisco APs, 1800-2800 series.  Nedi does not seem to handle these APs correctly.
If look at the AP-view, Nedi does not display the "Connection" value (what switch and interface the AP is connected to).
but in "Maps" in the same view I can see the CDP value.
 
For all older APs this works.  I have attached a screenshot to this message so you can see for yourself.

Is CDP enabled on both sides? On the switch and switchport and enabled in WLC?

Yes CDP is enabled om both sides,  in fact I have older APs in the same switcher and controllers they show up as they should.
If I look into the Link table,  all other APs but 1800/2800 is registered there.
If look in the switch and run "sh cdp neighb"   the all APs show up

When I look at the connected switch the APs will show up as cdp neighbors..   Its only in AP-view its something wrong

I attached a file showing this from the switch-view

What is the exact CDP description of the AP? NeDi recognizes AIR-AP, AIR-CAP or AIR-LAP. If this string is not showing up it won't be identified as AP. You can still add a matching string (or regexp) to nosnmpdev in nedi.conf to get the links and avoid NeDi trying SNMP on it...

Ah, I see now. There's something in 1.6 causing this! In libsnmp.pm line 2315 you can change AIR-[CL]AP to  AIR-[CL]?AP
