Cisco Wireless :: AIR-CAP2602I-E-K9 Configure SNMP From WLC 5508?

How are certain settings/config transfered across to the AP's from the WLC, e.g. username and passwords, snmp strings etc.... I assume this is when the AP joins the WLC.More to the topic of the original question I had in mind, is it possible and if so, how? - to configure snmp read and write string from the WLC and push this config out to AP's. I can't believe someone will have to sit down (me) and SSH to 150+ AP's per WLC to configure SNMP.
 
One of the buildings lost connectivity to the WLC's breifly a couple of days ago and all seemed to have lost their SNMP settings. Connectivity was restored, but couldnt poll the APs. When I SSH'd on to a couple of AP's, and manually configured the snmp-server community xxxx ro - SNMP started working again. Since there are many, there must be an easier way of doing it.I've tried resetting the AP from the WLC and also powering down AP's and bringing them back up.
