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.
To configure a management address to be advertised and its encoding format on a port or group of
ports:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter Ethernet interface
view or port group view.
•
Enter Layer 2/Layer 3 Ethernet
interface view:
interface
interface-type
interface-number
•
Enter port group view:
port-group manual
port-group-name
Use either command.
3.
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.
•
For a Layer 2 Ethernet port, the
management address is the main IP
address of the lowest-ID VLAN
carried on the port. If none of the
carried VLANs is assigned an IP
address, no management address
will be advertised.
•
For a Layer 3 Ethernet port, the
management address is its own IP
address. If no IP address is
configured for the Layer 3 Ethernet
port, no management address will
be advertised.
4.
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.
By setting the TTL multiplier, you can configure the TTL of locally sent LLDPDUs, which determines how
long information about the local device can be saved on a neighboring device. The TTL is expressed by
using the following formula:
TTL = Min (65535, (TTL multiplier × LLDPDU transmit interval))
