| Description | An entry in the clcCdpApCacheTable,
containing the information received via CDP on one
interface from one device. Entries appear when
a CDP advertisement is received from a neighbor
device. Entries disappear when CDP is disabled
on the interface or globally.
Consider a setup where two APs, 'AP1' and 'AP2'
have been connected to a CISCO-3750 switch.
Both the APs register with WLAN CONTROLLER 4400
which is on LAN/Internet/Intranet.
