CONFIGURACION DE UNA VLAN

 

PRACTICA 1                                      SEGUNDO PARCIAL

 

VLAN

Las VLAN se crea en el modo de configuración global mediante el comando vlan id de la VLAN. Una vez creadas las VLAN, se asignan a los puertos del switch a los que se conectara el router. Para realizar esta tarea, se ejecuta el comando switchport access vlan id de la VLAN desde el modo de configuración de la interfaz en el switch para cada interfaz a la cual se conectara el router.
