Cisco Aironet 1131AG and SNMP

[olafmarcos]

We have a Wireless Control System, 3 WLC and 190 APs. I need to monitor 802.11 radios through SNMP. The system is running with LWAPP and the APs are not accesible through SNMP (no response trying to acces them). I try to send traps to the SNMP server (Zabbix) but disabling the 802.11 Radio from the WLC, I don't see any trap about the Radio status or admin going down.

¿Are there any method to monitor the radio status through SNMP?

Thanks in advance,

Olaf

Hi Olaf,

The lwapp APs are not snmp-manageable but the controllers takes care of that. You can poll the WLC via SNMP and it will give you the radio status of all the APs.

I suggest using the Cisco MIB browser tool to find out more about the AIRESPACE mib that the WLC is using.

Thanks Nicolas...

I can query the Table of Interface Status but it is very hard to monitor due to the Index Interface is dynamic. I try to monitor through traps...

[Nicolas Darchis]

That's precisely where WCS has a useful side, in that it perfectly follows the dynamic of the WLC tables.

The WLC should be sending a trap if a radio goes down, is that not working ?

At the moment, I don't see that trap cause any radio go down. I try to disable it down administratively from the WLC console but not send the trap.

I will hope that if the interface goes down, I see the trap...

Regards,

Olaf
