Hi, You're looking for 'Lightning Arrestor'. Something like this. Make sure you get the right one for your AP connector (N / RP-TNC) and note they aren't infallible!  http://www.cisco.com/c/en/us/td/docs/wireless/lightning_arrestor/installation/guid...

Hi Renjith, What are you trying to achieve? In a controller based setup the APs do not support SNMP, you need to poll the WLC for information. Ric
