System Configuration Guide
In addition to the four mandatory TLVs, Release 3.6 software supports the basic
management TLV set. You can specify which of these optional TLVs to include
in the transmitted LLDPDUs for each port.
The optional management TLVs are as follows:
•
Port Description TLV
•
System Name TLV
•
System Description TLV
•
System Capabilities TLV (indicates both the system supported capabilities
and enabled capabilities, such as end station, bridge, or router)
•
Management Address TLV
Transmitting LLDPDUs
When a transmit cycle is initiated, the LLDP manager extracts the managed
objects from the LLDP local system MIB and formats this information into TLVs.
The TLVs are then inserted into the LLDPDU.
LLDPDU are regularly transmitted at a user-configurable transmit interval
(tx-delay), or when any of the variables contained in the LLPDU is modified on
the local system (such as system name or management address). Tx-delay is the
minimum delay between successive LLDP frame transmissions.
TLV system MIBs
The LLDP local system MIB stores the information for constructing the various
TLVs to be sent. The LLDP remote systems MIB stores the information received
from remote LLDP agents.
LLDPDU and TLV error handling
LLDPDUs and TLVs that contain detectable errors are discarded. TLVs that are
not recognized, but that also contain no basic format errors, are assumed to be
validated and are stored for possible later retrieval by network management.
