Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 or Layer 3
Ethernet interface view or
Layer 2 aggregate interface
view.
interface interface-type

N/A
3. Allow LLDP to advertise the
management address in
LLDPDUs and configure the
advertised management
address.
• In Layer 2 or Layer 3 Ethernet
interface view:
lldp [ agent { nearest-customer
| nearest-nontpmr } ]
tlv-enable basic-tlv
management-address-tlv
[ ip-address ]
• In Layer 2 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 LLDPDUs,
and nearest non-TPMR bridge
agents cannot advertise the
management address in LLDPDUs.
4. Configure the encoding
format of the management
address as character string.
• In Layer 2 or Layer 3 Ethernet
interface view:
lldp [ agent { nearest-customer
| nearest-nontpmr } ]
management-address-format
string
• In Layer 2 aggregate interface
view:
lldp agent { nearest-customer
| nearest-nontpmr }
management-address-format
string
By default, the management
address is encapsulated in the
numeric format.
Setting other LLDP parameters
The TTL 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))
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:
