Optional
By default, all types of
LLDP TLVs except
location identification
TLV are advertisable
on a Layer 2 Ethernet
port.
Configuring the Management Address and Its Encoding Format
LLDP encodes management addresses in numeric or character string format in management address
TLVs.
By default, management addresses are encoded in numeric format. If a neighbor encoded its
management address in character string format, you must configure the encoding format of the
management address as string on the connecting port to guarantee normal communication with the
neighbor.
Follow these steps to configure a management address to be advertised and its encoding format on one
or a group of ports:

Required
Use either command
Allow LLDP to advertise the
management address in
LLDPDUs and configure the
advertised management
address
lldp management-address-tlv
[ ip-address ]
Optional
By default, the management
address is sent through
LLDPDUs, and the
management address is the
main IP address of the
lowest-ID VLAN carried on the
interface. If the VLAN is not
assigned a main IP address,
127.0.0.1 is used.
Configure the encoding
format of the management
address as character string lldp
management-address-format
string
Optional
By default, the management
address is encapsulated in the
numeric format.
Setting Other LLDP Parameters
The Time To Live TLV carried in an LLDPDU determines how long the device information carried in the
LLDPDU can be saved on a recipient device.
