Use of USB for IOS transfer

[eurobadger]

Hi All

I have been trying to find a definitive answer on cisco.com, but have failed so far.

Assuming I am on a router that has USB port, and an IOS that supports copy to and from USB, can anyone tell me the maximum size USB memory key I can use? I have seen various things that talk about Cisco-provided 256MB drives for tokens, 2 GB also allowed for tokens. The Cisco-provided and Cisco-badged devices are noted as having the correct drivers in the IOS for their use.

However these documents are a couple of years old at least, and these things do move on...


Many thanks

I believe it would be 4GB since it only supports the FAT (not FAT32) file system.
