Hola..

estoy intentando configurar un router cisco 877 el cual se me resiste, toda la configuracion de base esta correcta pero cuando necesito configurar la vlan 1, no se como entrar en la configuracion d la misma. tengo que crear primeramente la vlan? que comando necesito. alguien puede ayudarme…

pasos que sigo al configurar vlan1=>BCN#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
BCN(config)#interface vlan 1
^
% Invalid input detected at ‘^’ marker.

BCN(config)#
