Bulk rommon boot?

[Jesse Dungeon]

Hello,

I am currently trying to figure out if there is any way to boot multiple switches into the ROMMON mode.

I am wondering if there is some sort of tool which makes this easier, if there is an automated way or if I have to do this manually.

Thanks in advance.

Not that i am aware any tool, if the switch booting normally, you can write a script to remove IOS image and reload device, that go in to ROMMON.

Thank you for your answer,

unfortunately I cannot log into the devices myself, since there is a configuration with credentials which I do not have.

So there is no option now ,  you need to go password recovery process.

           - As you state rommon-boot requires manual actions usually , you can not do that in bulk.

In theory, if "something", in bulk, resets the boot/config register to boot into ROMMON, and then reloaded the device, that should meet your goal.  Unfortunately, cannot suggest any "tool" to do this, easily.

1. Without knowing what platform, the easiest way to boot all platforms into ROMMON is to format the flash/bootflash.  
2. For routers and some switches, changing the config-registry will guarantee booting into ROMMON. 
3. For ASR1k &/or ISR 4k, one sure-fire way to boot into ROMMON is to take advantage of CSCvg37458 and configure the wrong boot-variable statement.
