information received from neighbors.
 CDP Aware Select CDP awareness.
The CDP operation is restricted to decoding incoming CDP frames ( The switch
doesn't transmit CDP frames ). CDP frames are only decoded if LLDP on the
port is enabled.
Only CDP TLVs that can be mapped to a corresponding field in the LLDP
neighbours' 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 neighbours' 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 neighbours 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 neighbours' table.
If all ports have CDP awareness disabled the switch forwards CDP frames
received from neighbour 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 removed when the hold time is exceeded.
