5.9 LLDP
5.9.1 Parameter Configuration
LLDP is a second layer topology discovery protocol, the basic principle is: network equipment to the adjacent
equipment issued its notice of state information, and each port of all equipment are stored with their own
information, if a local device state changes, also can with its directly connected neighbor devices to send updated
information to that neighbor devices will be the information stored in the standard SNMP-MIB library. Network
management system can query from the SNMP-MIB Library of the current second layer connection. It should be
noted that LLDP is only a remote device status information discovery protocol, it can‘t complete the network
device configuration and port control and other functions.
Configuration item
meaning
Disable
The switch will not send the LLDP message, and will reduce the LLDP message
received from the neighbor.
Enable
The switch will send the LLDP message, which will analyze the LLDP message
received from the neighbor.
TX interval
The switch status is not changed, the device periodically to the neighbor nodes
to send LLDP packets, the interval time is called to send LLDP message
interval
.
RX
Switch will not send out the LLDP information, but the information from the
vicinity of the unit LLDP analysis.
TX
Will reduce the LLDP information received from the neighbors, but will send
LLDP information.
5.9.2 Neighbor Information
LLDP management address is the address of the network management system identification and management.
Management address can clearly identify a device, it is conducive to the network topology, network management,
network management. The management address is encapsulated in the Management Address TLV field of the
LLDP message and is sent to the neighbor node.
