HP A3100-8 v2 SI User 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.
Protocols and standards
• IEEE 802.1AB-2005, Station and Media Access Control Connectivity Discovery
• ANSI/TIA-1057, Link Layer Discovery Protocol for Media Endpoint Devices
LLDP configuration task list
Complete these tasks to configure LLDP:
Task Remarks
Enabling LLDP Required
Setting the LLDP operating mode Optional
Setting the LLDP re-initialization delay Optional
Enabling LLDP polling Optional
Configuring the advertisable TLVs Optional
Configuring the management address and its
encoding format
Optional
Setting other LLDP parameters Optional
Performing basic LLDP
configuration
Setting an encapsulation format for LLDPDUs Optional
Configuring CDP compatibility (available only on the A3100 v2 EI) Optional
Configuring LLDP trapping Optional
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:
