Protocols And Standards; Lldp Configuration Task List; Performing Basic Lldp Configuration; Enabling Lldp - HP A3100-8 v2 SI Configuration Manual

This is the fast sending mechanism of LLDP. With this mechanism, a specific number of LLDPDUs are sent
successively at 1-second intervals, to help LLDP neighbors discover the local device as soon as possible.
Then, the normal LLDPDU transmit interval resumes.
Receiving LLDPDUs
An LLDP-enabled port that is operating in TxRx mode or Rx mode checks the validity of TLVs carried in
every received LLDPDU. If valid, the information is saved and an aging timer is set for it based on the time
to live (TTL) value in the Time To Live TLV carried in the LLDPDU. If the TTL value is zero, the information
ages out immediately.

LLDP configuration task list

Complete these tasks to configure LLDP:
Task
Performing basic LLDP
configuration
Configuring CDP compatibility (available only on the A3100 v2 EI)
Configuring LLDP trapping
NOTE:
LLDP-related configurations made in Ethernet interface view take effect only on the current port, and those
made in port group view take effect on all ports in the current port group.

Performing basic LLDP configuration

Enabling LLDP

To make LLDP take effect on certain ports, you must enable LLDP both globally and on these ports.
Follow these steps to enable LLDP:
Enabling LLDP
Setting the LLDP operating mode
Setting the LLDP re-initialization delay
Enabling LLDP polling
Configuring the advertisable TLVs
Configuring the management address and its
encoding format
Setting other LLDP parameters
Setting an encapsulation format for LLDPDUs
