Hola Tadano.
El protocolo de descubrimiento de capa de
enlace (LLDP Link Layer Discovery Protocol) se especifica en el documento de
estándares IEEE 802.1AB.
LLDP identifica las interfaces en los
dispositivos y las interfaces conectadas a otros dispositivos.
Muestra la ruta entre un cliente, un Switch,
un Router, un servidor de aplicaciones y un servidor de red.
Puedes ejecutar el comando display
lldp neighbor [ interface
interface-type interface-number ] para conocer el equipo que se encuentra
en el otro extremo de esta interface, como se muestra a continuación:
<Huawei>
