By default, management addresses are encoded in numeric format. If a neighbor encodes its
management address in string format, configure the encoding format of the management address as
string on the connecting port. This guarantees normal communication with the neighbor.
To configure a management address to be advertised and its encoding format on a port:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2/Layer 3
Ethernet interface view, or
Layer 3 aggregate
interface view.
interface interface-type interface-number N/A
3. Allow LLDP to advertise
the management address
in LLDP frames and
configure the advertised
management address.
• In Layer 2 Ethernet interface view:
lldp tlv-enable basic-tlv
management-address-tlv [ ip-address ]
• In Layer 3 Ethernet interface view:
lldp [ agent { nearest-customer |
nearest-nontpmr } ] tlv-enable basic-tlv
management-address-tlv [ ip-address ]
• In Layer 3 aggregate interface view:
lldp agent { nearest-customer |
nearest-nontpmr } tlv-enable basic-tlv
management-address-tlv [ ip-address ]
By default:
• Nearest bridge agents
and nearest customer
bridge agents can
advertise the
management address in
LLDP frames.
• Nearest non-TPMR
bridge agents cannot
advertise the
management address in
LLDP frames.
4. Configure the encoding
format of the
management address as
string.
• In Layer 2 Ethernet interface view:
lldp management-address-format string
• In Layer 3 Ethernet interface view:
lldp [ agent { nearest-customer |
nearest-nontpmr } ]
management-address-format string
• In Layer 3 aggregate interface view:
lldp agent { nearest-customer |
nearest-nontpmr }
management-address-format string
By default, the encoding
format of the management
address is numeric.
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 × LLDP frame transmission interval + 1))
As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than 65535 will be rounded
down to 65535 seconds.
To change LLDP parameters:
