An entry (conceptual row) in the cdpCtAddressTable,
containing the information on one address received via CDP
on one interface from one device. Entries appear
when a CDP advertisement is received from a neighbor
device, with an Address TLV. Entries disappear when
CDP is disabled on the interface, or globally. An entry
or entries would also disappear if the most recently
received CDP packet contain fewer address entries in the
Address TLV, than are currently present in the CDP cache.
