3.
Allow LLDP to advertise the
management address in LLDP
frames and configure the
advertised management
address.
•
In Layer 2/Layer 3 Ethernet
interface view or management
Ethernet interface view:
lldp [ agent { nearest-customer
| nearest-nontpmr } ]

[ ip-address ]
•
In Layer 2/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/Layer 3 Ethernet
interface view or management
Ethernet interface view:
lldp [ agent { nearest-customer
| nearest-nontpmr } ]
management-address-format
string
•
In Layer 2/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:
