Port identifier.
Enables LLDP message transmit and receive modes for LLDP Protocol Data
Units. (Options: Disabled, Enabled - TxRx, Rx only, Tx only; Default: Disabled)
Enables decoding of Cisco Discovery Protocol frames. (Default: Disabled)
If enabled, CDP TLVs that can be mapped into a corresponding field in the LLDP
neighbors table are decoded, all others are discarded. 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 support system capabilities, but the CDP capabilities
cover capabilities that are not part of 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.
When CDP awareness for a port is disabled, the CDP information is not removed
immediately, but will be removed when the hold time is exceeded.
The port description is taken from the ifDescr object in RFC 2863, which includes
information about the manufacturer, the product name, and the version of the
interface hardware/software.
The system name is taken from the sysName object in RFC 3418, which contains
the system's administratively assigned name. To configure the system name, see
the Configuring System Information section on page 39.
The system description is taken from the sysDescr object in RFC 3418, which
includes the full name and version identification of the system's hardware type,
software operating system, and networking software.
The system capabilities identifies 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.
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.
The interface number and OID are included to assist SNMP applications in the
performance of network discovery by indicating enterprise specific or other start-
ing points for the search, such as the Interface or Entity MIB.
Since there are typically a number of different addresses associated with a Layer
3 device, an individual LLDP PDU may contain more than one management
address TLV.
