Setting Other Lldp Parameters - H3C S3100 Series Operation Manual

To do...
Enter Ethernet interface view
Enable LLDP to advertise
management address TLVs
and configure the advertised
management IP address

Setting Other LLDP Parameters

The TTL TLV carried in an LLDPDU determines how long the device information carried in the LLDPDU
can be saved on a recipient device.
You can configure the TTL of locally sent LLDP frames to determine how long information about the
local device can be saved on a neighbor device by setting the TTL multiplier. The TTL is expressed as
follows:
As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than it will be rounded
down to 65535 seconds.
Follow these steps to change the TTL multiplier:
To do...
Enter system view
Set the TTL multiplier
Set the LLDPDU transmit
interval
Set LLDPDU transmit delay
Set the number of LLDP frames
sent each time fast LLDPDU
transmission is triggered.
Both the LLDPDU transmit interval and delay must be less than the TTL to ensure that the LLDP
neighbors can receive LLDP frames to update information about the device you are configuring before
it is aged out.
Use the command...
interface interface-type
interface-number
lldp
management-address-tlv
[ ip-address ]
TTL = Min (65535, (TTL multiplier × LLDPDU transmit interval))
Use the command...

lldp hold-multiplier value
lldp timer tx-interval interval
lldp timer tx-delay delay
lldp fast-count count
Required
Optional
By default, the management
address is sent through LLDPDUs.
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.
