  1. IOS Upgrade using Cisco Universal Serial Bus (USB) Card

  2. Introduction One of the primary architectural enhancements of the Cisco 1800, 2800, and 3800 series integrated services router is the integration of USB ports to provide increased flexibility and simplicity when delivering different applications and services.

  3. Introduction cntd. To take advantage of two new features available by the USB ports, Cisco requires a minimum IOS version 12.3(14)T. • These features include: • The USB eToken, not a Cisco product, sold by Aladdin knowledge Systems www.aladdin.com/cisco • The USB Flash memory http://www.cisco.com/en/US/prod/collateral/modules/ps6247/product_data_sheet0900aecd80232473.html

  4. How The USB etoken Works • The USB eToken uses smart card technology to protect a small area of memory. • It grants access using a personal identification number (PIN). • The USB eToken is inserted in a USB port. • The user enters the PIN and unlocks the USB eToken, then user retrieves the credentials and copies them into running memory. • The router erases the credentials from running memory, as soon as the USB eToken is removed from the USB port

  5. USB flash memory • The Cisco USB flash memory module can be used to store an image or configuration file. Unlike the USB eToken, the Cisco USB flash memory module is nonsecure; but, is available in 64-MB, 128-MB, and 256-MB capacities. • The Cisco 1800, 2800 and 3800 routers supports booting directly from a USB device.

  6. Connecting a USB Module to the Router USB Port To connect a Cisco USB flash memory module or the Aladdin USB eToken to a router USB port, simply insert the module into the port as shown below. The module can be inserted in only one way, and it can be inserted or removed whether the router is powered up or not. • Note:USB hubs are not supported on Cisco Access routers

  7. Connecting a USB Module to the Router USB Port (cntd.) Once you insert a USB token into the port (and IOS release 12.4 recognizes tokens up to at least 1GB), you get a generic storage device (usbflash0: and/or usbflash1:) that can be used to upgrade your router image. • Q. Can I boot an image directly from the USB Flash module? • A. Yes. USB drivers have been added to rommon, starting with version 12.4(13r)

  8. IOS Upgrade from USB Your router already has an image on it when you receive it. Nevertheless, you may want to load a different image onto the router at some point. For example, you may want to upgrade your software to the latest release, or you may want to use the same Cisco IOS release for all the routers in a network.

  9. IOS Upgrade from USB • First determine which Cisco IOS releases and feature sets support your platform and required features. • Go to Cisco Feature Navigator at http://www.cisco.com/go/fn. • Next choose the Cisco IOS release and system image to which you want to upgrade

  10. IOS Upgrade from USB If the USB flash memory does not come preloaded with the required IOS, download the required IOS to your PC using your CCO account • Insert the USB card into your PC and copy the downloaded IOS to the USB card • Confirm that the IOS is present in your USB card after you insert it back into your router.

  11. IOS Upgrade from USB show usbflash0: • Use this command to display a list of all files and directories in USB flash memory: Router#show usbflash0:Directory of usbflash0:/1 -rw- 28783540 Jan 22 2007 19:48:52 +00:00 c2800nm-advipservicesk9-mz.124-15.T7.bin 2 -rw- 4096 Nov 15 2007 13:07:04 +00:00 ._c2801-advipservicesk9-mz.124-10b.bin

  12. IOS Upgrade from USB Follow these steps to load the IOS from USB • Step 1 configure terminal • Use this command to enter global configuration mode: Router# configure terminal Router(config)#

  13. IOS Upgrade from USB • Step 2 no boot system • Use this command to delete all entries in the bootable image list, which specifies the order in which the router attempts to load the system images at the next system reload or power cycle: Router(config)# no boot system

  14. IOS Upgrade from USB • Step 3 boot systemflashsystem-image-filename • Use this command to load the new system image after the next system reload or power cycle. • For example: Router(config)# boot system flash usbflash0:c2800nm-advipservicesk9-mz.124-15.T7.bin

  15. IOS Upgrade from USB • Step 4 exit • Use this command to exit global configuration mode: Router(config)# exit Router#

  16. IOS Upgrade from USB • Step 5 show version • Use this command to display the configuration register setting: Router# show versioncisco Internetwork Operating System Software . Configuration register is 0x0Router#

  17. IOS Upgrade from USB • Step 6 copy run start • Use this command to copy the running configuration to the startup configuration: Router# copy run start • Step 7 reload • Use this command to reload the operating system: Router# reload

  18. IOS Upgrade from USB • Step 8 When prompted to confirm the reload, enter y: • Step 9 show version • Use this command to verify that the router loaded the proper system image: Router# show version Cisco Internetwork Operating System Software . System returned to ROM by reload System image file is " usbflash0:c2800nm-advipservicesk9-mz.124-15.T7.bin "
