Redes - Novato con vlans

Tengo un switch configurado con dos vlan (voz y datos), el equipo funciona bien si esta conectado directamente al equipo donde esta conectado el PBX.

Si yo conecto el nuevo switch que acabo de configurar por ejemplo al Switch A, B, C, ya no me funcionan los telefonos.

Si conecto un telefono a el cable en donde esta configurado la vlan de los telefonos directamente, el telefono funcionan, pero si conecto el switch y despues conecto un telefono a este switch, no me funciona, que pasa??
tengo que configurar un puerto trunk?? como o que le agrego (comandos o instrucciones)??



Espero y alguien me pueda ayuda, soy nuevo con las Vlans.

Saludos y gracias de antemano por la ayuda =)

Buenas noches

Usas tecnologia cisco?

Saludos

No, estoy trabajando con equipos marca Dell...pero me imagino que en teoria y por lo que he visto trabajan muy similar.

en cisco como se haria??

Buen dia


En el route tenemos un servidor dhcp que entrega las direcciones a las diferentes vlans data y voz.

en el router usamos interfaces virtuales para cada vlan.

Espero Te haya servido

Muchas gracias por el aporte Raymundo, pero ahora me paso lo siguiente, conecto un crossover cable and straight cable al puerto 23 de mi switch y el telefono funciona, pero si despues conecto un cable straight para conectar una pc el telefono se cae o deja de funcionar.

si conecto un cable straight o derecho, me da conexion para la red, que pasa??

no puedo tener ambos cables conectados al mismo tiempo por que uno de los dos se cae o deja de funcionar??

estas es la configuracion de mi equipo:

Buen dia


Probaste con otro cable straight cable para verificar que el cable bien?


Saludos,

Si, pero sigue igual; si conecto uno funcionan bien, pero si conecto ambos, uno de los dos servicios se cae, alguna idea?

Buen dia.


Hay no se que puede estar pasando ya que nunca he usado productor dell ni en ecenarios


Saludos.
