Topology Discovery (LLDP)
Topology Discovery (LLDP)
The RocketLinx ES7528 supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) functionality
that can help to discovery multi-vendor’s network devices on the same segment by a network monitoring system (NMS) that
supports LLDP functionality.
With LLDP functionality, NMS can easily maintain the topology map, display port ID, port description, system description,
and VLAN ID. Once a link failure occurs, the topology changes the events that can be updated to the NMS as well. The LLDP
Port State can display the neighbor ID and IP learnt from the connected devices.

LLDP Timer
This is the interval time of each LLDP in seconds; valid values are from
5 to 254. The default is 30 seconds.
LLDP Hold time
The Time to Live (TTL) timer. The LLDP state expires when 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.
