Setting Other Lldp Parameters; Setting An Encapsulation Format For Lldpdus - HP A6600 Configuration Manual

To do...
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 neighbor device. The TTL is expressed using
the following formula:
TTL = Min (65,535, (TTL multiplier × LLDPDU transmit interval))
As the expression shows, the TTL can be up to 65,535 seconds. TTLs greater than 65,535 are rounded
down to 65,535 seconds.
To change the TTL multiplier:
To do...
1. Enter system view
2. Set the TTL multiplier
3. Set the LLDPDU transmit
interval
4. Set LLDPDU transmit delay
5. Set the number of LLDPDUs
sent each time fast LLDPDU
transmission is triggered
To ensure that the LLDP neighbors can receive LLDPDUs to update information about the current router
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 the following formats: Ethernet II or SNAP frames.
• With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames and only
processes incoming, Ethernet II encapsulated LLDPDUs.
With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames, and it only
•
processes incoming SNAP-encapsulated LLDPDUs.
By default, LLDPDUs are encapsulated in Ethernet II frames. If the neighbor devices encapsulate LLDPDUs
in SNAP frames, configure the encapsulation format for LLDPDUs as SNAP to guarantee normal
communication with the neighbors.
