Gracias por tu respuesta Julio. El día de ayer encontré que el examen SITCS cambió de versión, de 1 a 1.5. El examen anterior tenía la nomenclatura 300-207, el nuevo tiene la nomenclatura 300-210 y ya incluye Firepower. Gracias por la información de los libros.
Saludos

Amig@s que tal!
Necesito su ayuda.
Estoy buscando qué examen del CCNP Security cubre el contenido de Firepower, con Firepower me refiero a todo, FMC, los sensores, configuración del IPS....
Hoy estuve investigando toda la tarde y lamentablemente llegue a la conclusión que ninguno de los 4 examenes :( :( :( !!!!!!!!!!!!! Espero estar equivocado. En la página de Cisco solo aparece esto al inicio pero no dan más detalles:
Caso alguien tenga información del tema les agradeceré compartirme.
Saludos

Hi Leo. Unfortunately I can not give you this information, I do not think it's sensitive information, but the commitments I have forbid me from revealing any type of information.
Always thanks for the interest and help.
Regars,
JG

Thanks. I watched the watts consumption for my power supplies.
The current in amps (A) is equal to the power in watts (W), divided by the voltage in volts (V), for those power supplies I can work with 20 A fine.

Hi Leo
I opened the case in the TAC. Basically they told me not to restart the switch since the switch could not start again. I tried to force the installation from the flash memory of the standby switch, the master switch, which was the one with the problem, showed me a writing error in the flash memory and it restarted. After that the switch enter in Rommon mode, in Rommon mode I couldn't access the flash memory and boot again. Thanks to God the switch was under contract and I could request the replacement with an RMA. At this moment I already have the new switch running smoothly and updated. If someone has the same problem, it is very likely that the error is due to a failure in the flash memory, so be careful with the actions that are done in the switch since if it reboots, it may be unusable. Thanks to all who could read the posts and to you Leo for the help.

Hola Julio Moisa
Te cuento que abrí el caso en el TAC. Básicamente ellos me dijeron que no reiniciara el switch ya que posiblemente el switch no iniciaría nuevamente.
Yo intenté forzar la instalación desde la memoria flash del switch standby, el switch principal, que era el del problema, me mostró un error de escritura en la memoria flash y se reinició.
Después del reinicio el switch entró en Rommon mode y ya no pude acceder a la flash ni bootear nuevamente. Gracias a Dios ese switch estaba con contrato vigente y pude solicitar el reemplazo con un RMA. En este momento ya tengo el nuevo switch funcionando sin problemas y actualizado.
Caso alguien tenga el mismo problema, es muy probable que el error se deba por un fallo en la memoria flash, así que cuidado con las acciones que se hagan en el switch ya que si se reinicia posiblemente quede inservible.
Gracias a todos los que pudieron leer los posts y a ti Julio por la ayuda.

Thanks Leo.
The following is the output of copying the file from the USB:
Switch#show usbflash0-2: -#- --length-- ----------date/time---------- path 2 537577577 Aug 14 2018 07:22:36.0000000000 +00:00 cat3k_caa—universalk9.16.03.06.SPA.bin 3467116544 bytes available (537395200 bytes used) Switch#copy usbflash0-2: flash: Source filename []? cat3k_caa—universalk9.16.03.06.SPA.bin Destination filename [cat3k_caa—universalk9.16.03.06.SPA.bin]? %Error opening flash:/cat3k_caa—universalk9.16.03.06.SPA.bin (I/O error)
The I/O error is present. On the side of the TFTP server everything looks good, the transmission is aborted by the client. I made the test from two TFTP servers on two different PCs, I had ping to the TFTP servers PC's.
I hope you can give me a hint as to what may be happening. Thanks for your time and help.

Estoy actualizando un switch 3850, el switch corre en este momento la imagen 03.07.03E y quiero actualizar a la versión Denali cat3k_caa-universalk9.16.03.06.SPA.bin. Cuando intento transferir la imagen al switch vía tftp tengo el siguiente error I/O, ese error me da al transferir cualquier archivo, también probe un txt; al hacer la transferencia por USB obtengo el mismo error, eso me lleva a la conclusión de que puede ser algún tipo de bloqueo con la memoria flash:
Estuve buscando en todos los foros y no encontré ningúna información sobre ese error. La información del espacio en la memoria es la siguiente: 3458338816 bytes total (2491412480 bytes free) Alguien puede ayudarme

I am updating a 3850 switch, the switch is currently running the image 03.07.03E and I want to update to the Denali version cat3k_caa-universalk9.16.03.06.SPA.bin.
When I try to transfer the image to the switch via tftp I have the following error I / O, that error gives me when transferring any file, also try a txt; when doing the transfer by USB I get the same error, that leads me to the conclusion that it can be some type of block with the flash memory:
I was looking in all the forums and I did not find any information about that error.
The space information in the memory is the following:
3458338816 bytes total (2491412480 bytes free)
Can anybody help me?
