Only CDP TLVs that can be mapped to a corresponding field in the LLDP neighbors'
table are decoded. All other TLVs are discarded (Unrecognized CDP TLVs and
discarded CDP frames are not shown in the LLDP statistics.). CDP TLVs are mapped
onto LLDP neighbors' table as shown below.
CDP TLV "Device ID" is mapped to the LLDP "Chassis ID" field.
CDP TLV "Address" is mapped to 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 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 interfaces have CDP awareness disabled the switch forwards CDP frames
received from neighbor devices. If at least one interface has CDP awareness enabled
all CDP frames are terminated by the switch.
Note: When CDP awareness on an interface is disabled the CDP information isn't removed
immediately, but gets removed when the hold time is exceeded.
