Listar Interfaz del Router

Comandos para Ingresar a las Interfaces:

interface ethernet 0
interface fastEthernet 0/1
interface gigabitethernet 0/0
interface serial 1/0/1

Comandos para Mostrar el Estatus de las Interfaces:

Dos de los comandos más comunes para mostrar el estatus de las interfaces son show ip interface brief y show interfaces.

El primero lista las interfaces una por línea, con información básica como la dirección IP y el estado de la intefaz. El segundo comando lista las interfaces, pero con muchas más información por cada una.

Ejemplo: Listar Interfaz del Router

R1# show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
