4.13.5 Topology Discovery
The switch supports 802.1AB Link Layer Discovery Protocol, thus the 5428G can
be discovered by the Network Management System which support LLDP discovery.
With LLDP supported, the NMS can easier maintain the topology map, display
port ID, port description, system description, VLAN ID… Once the link failure, the
topology change events can be updated to the NMS as well. The LLDP Port State
can display the neighbor ID and IP leant from the connected devices.
LLDP: Select Enable/Disable to enable/disable LLDP function.
LLDP Configuration: To configure the related timer of LLDP.
LLDP Timer: The interval time of each LLDP and counts in second; the valid
number is from 5 to 254, default is 30 seconds.
LLDP Hold time: The TTL (Time to Live) timer. The LLDP state will be expired once
the LLDP is not received by the hold time. The default is 120 seconds.
Local port: the current port number that linked with neighbor network device.
Neighbor ID: The MAC address of neighbor device on the same network
segment.
Neighbor IP: The IP address of neighbor device on the same network segment.
