Hello,

        I have more than 200 Cisco Lwap AP and i don't want them to be shown in the device list.

My wireless lan is 10.110.19.0/24 where from 10.110.19.1 to 10.110.29.20 i have all my WLAN Controller and WCS.

I have excluded in Netfilter all the AP  IPs

netfilter ^10\.110\.19\.([1-9]|1[0-9]|20)$

But now all the APs are discovered with IP 0.0.0.0 (not with the 1.0.7 version)

I've tried to border them as i did for all my Cisco telehone (working for these device), since all the LWAP ID are AP* i have included in the border.

border   ^SEP*|^AP*

But the device are yet discovered.

Many thank's

Are you also excluding your WLC from discovery?

If not, you may be picking up the APs from the WLC.  See also the nosnmpdev string in nedi.conf.

Another thing just occurred to me.  It appears your netfilter may not be doing what you expect it to (either that or there is a typo in your problem description).  In other words,

"netfilter ^10\.110\.19\.([1-9]|1[0-9]|20)$"

If I'm reading it correctly, will only filter addresses in the range:

10.110.19.1 - 10.110.19.20

Yet you state your Wireless infra is in the range 10.110.19.0 - 10.110.29.20... is that a typo?  I.e. did you actually mean be 10.110.19.1 - 20 or is it really 10.110.19.1 - 10.110.29.20?

At any rate, the 1st range (in your netfilter) does not accommodate 200+ devices & the second range, while quite a large network range for ~200 devices, is not covered by your netfilter.

Note:  just excluding your Wireless LAN ctrlr (WLC) from discovery will not necessarily mean that NeDi will skip discovery of the APs (e.g. if they are running CDP or SNMP is configured, NeDi will find them).  So you may need to exclude the IP address range of your APs as well.

After re-reading for the 5th time :-[, I think I understand what you're saying.

Your entire wifi infra is in the network 10.110.19.0 /24 (10.110.19.0 - 254) & your WLC(s) & WCS are in the range 10.110.19.1 - 20.  Finally, you're excluding the WCS/WLC range from discovery w/ your netfilter, & 10.110.29 was a typo in your post.

Suggest you use a netfilter that excludes your entire wireless network range as follows (just shorten your existing regex string):

netfilter ^10\.110\.19\.

That should tell NeDi to skip any address that begins w/ 10.110.19. (you may also need to modify the nosnmpdev string in nedi.conf as well, to remove reference to anything found in a Cisco model #).

Thank's for the reply,


        You get it right , i have the wlan controller and wcs in the range 10.110.19.1-20 , and probably the AP with address 0.0.0.0 are imported from these devices.

About excluding all the wireless range 10.110.19.0/24, the problem is that I would like to controll/backup wlan controllers inside Nedi  so what I would need is to  find a way to have the wlan controller and not the AP

What, I spend hours in the basement implementing WLC support and now you don't want it? ;) Why?

Are those APs mode 15 (controlled AP discovered via switch) or 16 (controlled AP discovered via controller) in device list? You can prevent discovering the first one with border, rather than netfilter (the latter only works on snmp devices)

Thank's Remo.
 

      I absolutely need and want to control all my Wlan Controllers inside Nedi, you did a great job   :D

I think the AP are discovered via controller, without the netfilter they are discovered with address  10.110.19.X,  with the filter active they are discovered all with network address 0.0.0.0

I've tried to border the AP as i did for all my Cisco telephones (working for these device), since all the LWAP ID are AP* i have included in the border.

border   ^SEP*|^AP*

But the device are yet discovered.

Thank's

Do you mean with discovered as it tries SNMP? This can be avoided by nosnmpdev rather than border. Because then you get IP addresses (as you observed) as well as links from the switches, which completes the topology view...
