Recently I ran into an unexplainable issue when I turned on CDP on our 2 WiSM's. I wanted to set up the switchport tracing feature and from what I understand, cdp is necessary to use this feature. On the 2 WiSM's, I enabled CDP under wireless>access points>Global Configuration and I click the check box to enable CDP. Using WCS, I audited the AP's and verified that they all have CDP enabled. After a few days, I noticed AP's were dropping connection with the WiSM's, the alarms said "The Access Point is not able to draw enough power." I ssh'd into one of the problematic AP's and cleared the private config. After attempting a reset configuration, the device continued to be stuck in a boot loop (I had a continuous ping that would reply for 15 pings, then drop 15 over and over).
Ultimately, I ended up disabling CDP and these AP's started working again. It seems from what I noticed that this issue only happened on Cisco 1242 access points. I tried to research to see if anyone else has had this issue, but my efforts did not yield any resolution.
Has anyone run into this issue or can explain why CDP might cause this issue?
