This is a template variable to enable / disable CDP
on all APs.
When 'true' is set, then internally CDP is enabled
on all APs associated with the Controller.
When 'false' is set, then internally CDP is disabled
on all APs associated with the Controller.
However, setting this attribute has no effect when CDP
is disabled globally, that is when the cdpGlobalRun from
the CISCO-CDP-MIB is set to 'false'on the Controller.
