Layer 2 aggregate interface
view.

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