There was no evident logs in the syslog of the WLC, but when we connected to the console port of the access point, we could see the follow errors: *Oct […]

Have you dreaded the awful task of checking configuration, ARP- and MAC-tables as well as CDP-information of several switches? Does the switches support CDP? Then there is really no problem! =)
From time to time, IT personell find it feasible to purchase autonomous access points for later converting them to lightweight access points which connects to a central Wireless LAN Controller (WLC). Fortunately for us, the conversion from autonomous to lightweight is simple and straight forward. In this example I’ve converted a SAP1602i access point.
