Remarks
Enable management address
advertisement in LLDPDUs,
and optionally, configure a
management IP address if
needed.
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 encapsulation
format of the management
address in the string format
lldp management-address-format
string
Required
By default, the
management address is
encapsulated in the
numeric format.
Setting the TTL Multiplier
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:
