Alerta en Switch Catalyst 2960 x Series

[Jcorniel]

Buenos días, gusto en saludarles nuevamente.

En esta ocasión quiero contarle algo que me sucedió configurando un switch 2960-x series.

Este switch totalmente nuevo, le monte una configuración usando TFTP de otro switch, al culminar la configuración, me arrojo el error que aparece en la siguiente imagen:

Un detalle, tenia el switch conectado a Internet al momento de realizar la configuración por TFTP. Luego empezó a tener un comportamiento extraño en su funcionamiento. Incluso llego a bloquear el acceso con una contraseña.

Por favor me podrian guiar e indicar que podría haber pasado?

Hola Corniel,

Es posible que tu dispositivo le este pegando al Field Notice: FN - 64175:

https://www.cisco.com/c/en/us/support/docs/field-notices/641/fn64175.html

Por favor revisa el mismo ya que plantea workaround:

For C2960X switches

1. Check the software version. If you have a version earlier than Version 15.0(2a)EX5, upgrade to Version 15.0(2a)EX5 or later. Versions 15.2(2)E4 and later are recommended.
2. If you already upgraded to Version 15.0(2a)EX5 or later, remove all the power cables and connect them back in order to hard reset (power cycle) the device.
3. If the issue still persists after an upgrade/hard reset or if there is a RPS in the system and it does not respond, upgrade to Version 15.2(2)E4.
   Note:When you upgrade a switch from EX releases to Version 15.2(2)E4, always perform a hard reset.

Espero esta información te sea útil.

Saludos,

[Jcorniel]

aparentemente entonces la solucion seria, actualizar el S.O del switch?

Si tienes contrato de soporte Intenta abrir un caso con el TAC.

Hola Corniel,

Yo diria que:

1. Quitar todos los cables de poder y volver a conectarlos para hacer una especie de "hard reset" del equipo.

2. Si lo anterior no funciona entonces ´proceder con el upgrade a 15.2(2)E4. Aunque también podrías ir directo con el upgrade.

3. Ya si con el upgrade no se obtiene el resultado esperado, entonces allí sí abrir un caso con TAC adjuntando de una vez el output de los comandos:

show tech-support

show hardware

Saludos.

Hola,

Si en efecto, reliace un reseteo de fabrica al switch, borre la configuracion, las vlan, dejandolo de cero. Pero el problema aun persistio.

Tienes algun tutorial de como actualizar o hacer UPgrade a los switch? Estaria agradecido con esto.

Saludos.
