Configuring the Management Address
The management address of a device is used by the network management system to identify and
manage the device for topology maintenance and network management. The management address is
encapsulated in the management address TLV. LLDP encodes management addresses in numeric
format in management address TLVs.
Make sure that a neighbor also encodes its management address in numeric format to guarantee
normal communication with the neighbor.
Follow these steps to configure a management address to be advertised on a port:
To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet interface view
interface interface-type
interface-number
Required
Enable LLDP to advertise
management address TLVs
and configure the advertised
management IP 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.
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.
You can configure the TTL of locally sent LLDP frames to determine how long information about the
local device can be saved on a neighbor device by setting the TTL multiplier. The TTL is expressed as
follows:
TTL = Min (65535, (TTL multiplier × LLDPDU transmit interval))
As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than it will be rounded
down to 65535 seconds.
Follow these steps to change the TTL multiplier:
To do… Use the command… Remarks
Enter system view system-view —
Set the TTL multiplier lldp hold-multiplier value
Optional
4 by default.
Set the LLDPDU transmit
interval
lldp timer tx-interval interval
Optional
30 seconds by default
Set LLDPDU transmit delay lldp timer tx-delay delay
Optional
2 seconds by default
