USB Port Information
The Cisco 7201 provides a USB port that can be used with a USB Flash memory module as secondary
storage, and can be used to store Cisco IOS images, data, and configuration files. The Cisco 7201 USB
port can also be used with the Aladdin USB eToken Pro key. This USB device can be used for the
following functions:
•
The Cisco USB Flash memory module can be used to store an image or configuration file like a
CompactFlash Disk. Unlike the Aladdin USB eToken Pro key, the Cisco USB Flash memory module
is nonsecure. See
Table A-5 on page A-4
for available USB token configurations and product
numbers.
•
The USB eToken Pro key by Aladdin Knowledge Systems provides a secure means to store and
deploy information, such as a bootstrap configuration or VPN credentials, separate from the router
chassis. The Aladdin USB eToken Pro key uses smart card technology to protect a small area of
memory and grants access using a personal identification number (PIN). When IP Security (IPSec)
VPN credentials are stored on the Aladdin USB eToken Pro key, they are safely external to the
router. When the USB eToken is inserted in a USB port, the router can pass the PIN and unlock it,
retrieving the credentials and copying them into running memory. When the Aladdin USB eToken
Pro key is removed, the router erases the credentials from running memory, ensuring that they
cannot be retrieved from the router itself.
Note
For more information about the eToken Pro key by Aladdin Knowledge Systems, see the

Note
The Cisco USB Flash memory module cannot be used to boot the router. The USB drivers
exist only in Cisco IOS software, not ROM Monitor mode (ROMmon). As a result, a Cisco
IOS image must be booted to load the drivers; only then can files be copied to and from the
USB Flash memory module.
