Principles
LLDP is a kind of point-to-point one-way issuance protocol, which notifies local device link
status to peer end by sending LLDPDU (or sending LLDPDU when link status changes)
periodically from the local end to the peer end.
The procedure of packet exchange:


When the device status is changed, the ISCOM2600G-HI series switch sends a LLDP packet
to the peer. To avoid sending LLDP packet continuously because of device status changes
frequently, you can configure a delay timer for sending the LLDP packet.
The aging time of Time To Live (TTL) in local device information about the neighbour node
can be adjusted by modifying the parameter values of aging coefficient, sends LLDP packets
to neighbour node, after receiving LLDP packets, neighbour node will adjust the aging time of
its neighbour nodes (sending side) information. Aging time formula, TTL = Min {65535,
(interval × hold-multiplier)}:

Type
Type
When the local device transmits packet, it gets system information required by TLV from
NView NNM (Network Node Management) and gets configurations from LLDP MIB to
generate TLV and form LLDPDU to transmit to peer.
The peer receives LLDPDU and analyzes TLV information. If there is any change, the
information will be updated in neighbor MIB table of LLDP and notifies the NView
NNM system.
Interval indicates the time period to send LLDP packets from neighbor node.
