To do… Use the command… Remarks
Configure the encoding format
of the management address as

mat string
Optional
By default, the management address is
encapsulated 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.
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 neighbor device. 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 65535 will be
rounded down to 65535 seconds.
Follow these steps to change the TTL multiplier:
To do… Use the command… Remarks
Enter system view system-view —
Set the TTL multiplier lldp hold-multiplier value
Optional
4 by default.
Set the LLDPDU transmit interval lldp timer tx-interval interval
Optional
30 seconds by default
Set LLDPDU transmit delay lldp timer tx-delay delay
Optional
2 seconds by default
Set the number of LLDPDUs sent
each time fast LLDPDU
transmission is triggered.
lldp fast-count count
Optional
3 by default
To ensure that the LLDP neighbors can receive LLDPDUs to update information about the current
device before it is aged out, configure both the LLDPDU transmit interval and delay to be less than the
TTL.
Setting an Encapsulation Format for LLDPDUs
LLDPDUs can be encapsulated in Ethernet II or SNAP frames.
