Setting Other Lldp Parameters - HP 6125G Configuration Manual

Step
3. Allow LLDP to advertise
the management
address in LLDPDUs and
configure the advertised
management address.
4. Configure the encoding
format of the
management address as
character string.

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 × 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.
Configuration restrictions and guidelines
To make sure that LLDP neighbors can receive LLDPDUs to update information about the current
•
device before it ages out, configure both the LLDPDU transmit interval and delay to be less than the
TTL.
It is a good practice to set the LLDPDU transmit interval to be no less than four times the LLDPDU
•
transmit delay.
If the LLDPDU transmit delay is greater than the LLDPDU transmit interval, the device uses the
•
LLDPDUs transmit delay as the transmit interval.
Configuration procedure
To change the TTL multiplier:
Step
1. Enter system view.
2. Set the TTL multiplier.
3. Set the LLDPDU transmit
interval.
4. Set the LLDPDU transmit delay.

Remarks
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.
Optional.
By default, the management address is
encapsulated in the numeric format.
