4:17 What if you have a USB stick with over 2 GB capacity, but you partition it? You put the IOS on the 2 GB partition, but leave the rest of the storage space unpartitioned. Would that work?

I dont get option for usb, I tried to see documents but no luck. I am having ISR4331/K9 at customer premsis. Will it work when the usb is connected to router and it will detect automatically?

There is a way to use a 8Gb Compact Flash to boot up?

I have a issue after it boots with the IOS i downloaded from you it asks directly for username and password, 1100 series. Also, when 'dir usb0' it says directory is empty, but when 'boot usb0: 'filename.bin'' it starts to boot the ios image. Could you help?

About new IOS, they require you to set new username and password (may need strength pass). Also, could you give me exactly your C1100 part#?

What format should the USB stick have?

@tigernet2509 2 жыл бұрын

Hi mate, You should use FAT32 standard. And remember that USB capacity must be equal or below 4GB. Best regards
