Configuring the management address and its encoding format
LLDP encodes management addresses in numeric or string format in management address TLVs.
By default, management addresses are encoded in numeric format. If a neighbor encoded its
management address in string format, configure the encoding format of the management address as
string on the connecting port. This guarantees normal communication with the neighbor.
To configure a management address to be advertised and its encoding format on a port or a group of
ports:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface view or
port group view.
• Enter Layer 2 or Layer 3 Ethernet
interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
3. Allow LLDP to advertise the
management address in LLDP
frames and configure the
advertised management
address.
lldp management-address-tlv
[ ip-address ]
Optional.
By default, the management
address is sent through LLDP
frames.
• For a Layer 2 Ethernet
port, the management
address is the main IP
address of the lowest-ID
VLAN carried on the
port. If none of the
carried VLANs is
assigned an IP address,
no management
address will be
advertised.
• For a Layer 3 Ethernet
port, the management
address is its own IP
address. If no IP address
is configured for the
Layer 3 Ethernet port, no
management address
will be advertised.
4. Configure the encoding
format of the management
address as string.
lldp management-address-format string
By default, the management
address is encoded in the
numeric format.
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.
