Object Description
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
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 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 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 removed when the hold time is exceeded.
Port Description Optional TLV: When selected, the "port description" is included in LLDP
information transmitted.
System Name Optional TLV: When selected, the "system name" is included in LLDP
information transmitted.
System Description Optional TLV: When selected, the "system description" is included in LLDP
information transmitted.
System Capabilites Optional TLV: When selected, the "system capability" is included in LLDP
information transmitted.
The system capabilities identify the primary function(s) of the system and
whether or not these primary functions are enabled. The information
advertised by this TLV is described in IEEE 802.1AB.
Management
Address
Optional TLV: When selected, the "management address" is included in
LLDP information transmitted.
The management address protocol packet includes the IPv4 address of the
switch. If no management address is available, the address should be the
MAC address for the CPU or for the port sending this advertisement. The
management address TLV may also include information about the specific
interface associated with this address, and an object identifier indicating the
type of hardware component or protocol entity associated with this address.
