Using USB Flash Drives in Cisco routers

Posted: 10 Mar 2011 09:46 AM PST


A few days ago I have written a post about Booting a Cisco Router from USB Flash. Related to that post and since I got some questions about the subject, it seems appropriate to add some more information about how USB Drives can be managed and used in Cisco IOS routers.

Some things to consider:

  • USB interfaces are supported from IOS release 12.3 (14) T IP Base and later.
  • All ISR and ISR G2 routers support USB flash drives.
  • Devices that have 2 USB ports, can use both USB memory sticks simultaneously.
  • You can use a USB extension cable; however USB hubs are not supported.
  • The IOS version supported on the router is independent of the type of USB (i.e doesn't matter if USB is version 1.1 or 2). The older ISRs use USB type 1.1 while the newest ISR machines use USB 2.0 types.
  • After inserting the USB flash memory into the corresponding port, the IOS software automatically recognizes it and generates a message on the console as shown below:

Mar 10 09:10:20.251: %USBFLASH-5-CHANGE: usbflash1 has-been inserted!

  • These routers also support the use of eTokens from Aladdin (security USB tokens).
  • The USB can be used to store and read both IOS images and configuration files.
  • The files stored on USB sticks are not encrypted.
  • Officially, Cisco routers support only USB devices from Cisco. However, it is possible to use any USB memory stick which does not require installation of specific drivers.
  • The only format supported by IOS is FAT16. NTFS file format on the USB drive is not supported yet.
  • USB flash drives can be formatted from IOS before being used.

How to format a USB drive from IOS

The formatting process is relatively simple using IOS:

Router # format ?
flash: Filesystem to be formatted
usbflash1: Filesystem to be formatted

Router # format usbflash1:

Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "usbflash1:".  Continue? [confirm]
Format: Drive communication & 1st Sector Write OK…

Format: All system sectors written. OK…
Format: Total data sectors in formatted partition: 8191435
Format: Total data bytes in formatted partition: -100952576
Format: Operation completed successfully.

Format of usbflash1 complete

From this point the USB flash drive can be used with all file system commands in the Cisco IOS.
