the LLDP neighbors table are decoded. All other TLVs are
discarded ( Unrecognized CDP TLVs and discarded CDP frame
are not shown in the LLDP statistic. Only ). CDP TLVs are
mapped into LLDP neighbors table as shown below.
CDP TLV "Device ID" is mapped into the LLDP "Chassis ID" field.
CDP TLV "Address" is mapped into the LLDP "Management
Address" field. The CDP address TLV can contain multiple
addresses, but only the first address is shown in the LLDP
neighbors table.
CDP TLV "Port ID" is mapped into the LLDP "Port ID" field.
CDP TLV "Version and Platform" is mapped into the LLDP
"System Description" field.
Both the CDP and LLDP supports "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 for a port is disabled the CDP
information isn't removed immediately, but will be removed when
the hold time is exceeded.
