Usage guidelines
The TTL 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 × LLDPDU transmit interval))
As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than 65535 will be
rounded down to 65535 seconds.
Examples
# Set the TTL multiplier to 6.
<Sysname> system-view
[Sysname] lldp hold-multiplier 6
Related commands
lldp timer tx-interval
lldp management-address-format string
Use lldp management-address-format string to change the data type of the value in the
management address TLV to string type.
Use undo lldp management-address-format to restore the default.
Syntax
lldp management-address-format string
undo lldp management-address-format
Default
The value in the management address TLV is numeric type.

Usage guidelines
LLDP neighbors must use the same data type for the value field in the management address TLV.
Examples
# Change the data type of the value in the management address TLV to string type on
GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/0/1
[Sysname-GigabitEthernet3/0/1] lldp management-address-format string
