CDP Commands
incapable devices, the CDP/LLDP capable devices may be able to receive the
advertisement from other device(s) only if the CDP/LLDP incapable devices flood
the CDP/LLDP packets they receives. If the CDP/LLDP incapable devices perform
VLAN-aware flooding, then CDP/LLDP capable devices can hear each other only if
they are in the same VLAN. It should be noted that a CDP/LLDP capable device
may receive advertisement from more than one device if the CDP/LLDP incapable
devices flood the CDP/LLDP packets.
To learn and advertise CDP information, it must be globally enabled (it is so by
default) and also enabled on interfaces (also by default).
