CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.
CDP TLV "Version and Platform" is mapped to the LLDP "System Description" field.
Both the CDP and LLDP support "system capabilities", but the CDP capabilities cover
capabilities that are not part of the LLDP. These capabilities are shown as "others" in
the LLDP neighbors’ table.
If all ports have CDP awareness disabled the switch forwards CDP frames received
from neighbor devices. If at least one port has CDP awareness enabled all CDP
frames are terminated by the switch.
NOTE: When CDP awareness on a port is disabled the CDP
information isn't removed immediately, but gets when the hold
time is exceeded.
