LLDP
8.1 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.
