Setting Other Lldp Parameters - HP A5830 Configuration Manual

By default, management addresses are encoded in numeric format. If a neighbor encoded its
management address in character string format, you must configure the encoding format of the
management address as string on the connecting port to guarantee normal communication with the
neighbor.
To configure a management address to be advertised and its encoding format on a port or group of
ports:
Step...
1. Enter system view
2. Enter
Ethernet
interface
view or
port
group
view
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 (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 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.

By default, the management address
is sent through LLDPDUs:

For a Layer 2 Ethernet port, 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
is advertised

For a Layer 3 Ethernet port, the
management address is its own IP
address. If no IP address is
configured for the Layer 3 Ethernet
port, no management address is
advertised
Optional
By default, the management address
is encapsulated in the numeric format
