LLDP support
Link Layer Discovery Protocol (LLDP) is a channel-layer protocol that allows network equipment to notify other devices on a local network of its existence and transmit its identity and capabilities to them, as well as receive the same information from them. The protocol is described in the IEEE 802.1AB standard.
Keenetic routers support the LLDP agent, i.e. the router informs other devices on the network about itself. For example:
As we can see, this information includes the MAC address, system name, model name, built-in operating system version, local IP address, operating mode, etc.
Important
The LLDP agent is enabled by default on private interfaces and disabled on public and protected interfaces.
However, a router does not support collecting information about neighbours through the LLDP protocol. This task can be partially solved by executing the following commands in the command-line interface (CLI):
show ip hotspot
and
show ip neighbour
The show ip hotspot command displays a list of hosts connected to the hotspot. The show ip neighbour command displays a list of entries about neighbouring hosts.
Complete information about command syntax is available in the Command Reference Guide, which can be found on our website in the Download Center.
For example:
(config)> show ip hotspot
