A little background

Before we get started, let’s review some of the specifics you need to know about using USB flash and CF cards with Cisco routers.

Router# show version Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(24)T1, RELEASE SOFTWARE (fc3) output suppressed ROM: System Bootstrap, Version 12.3(8r)YI, RELEASE SOFTWARE Router uptime is 2 minutes System returned to ROM by power-on System image file is 'flash:c870-advipservicesk9-mz.124-24.T1.bin' output.

  • The Cisco IOS can only read FAT-formatted flash drives.
  • The USB ports on a router are usually USB 2.0, but check the specifications
  • Site-to-Site IPsec VPN not coming up between ASA5510 and Cisco C870. I am trying to get this VPN between the ASA5510 running 7.0(8) and a C870 running 12.3(8r) YI which will not come up for some reason.

Ideally, USB flash can hold multiple copies of the Cisco IOS and multiple router configurations, and you can use it to easily move and copy those IOS files and configurations from router to router. And many times, when you’re physically at the router, the copying process can take place several times faster than it would over a LAN or WAN.

Let’s start

1>>> Take the USB flash drive from your pocket and connect it to the router. Immediately, the router told you like that:

If it does not show any thing, DO’NT WORRY. Sometimes devices can not find devices plugged on it. Go to step 2

2>>>As mentioned above, it needed a FAT format — the Cisco IOS only recognizes the FAT file system.

Here’s what it looked like:

At this point, as you can see below, I had a working USB flash drive.

3>>>Before copying a new IOS to your Cisco devices, you can make an copy of original IOS of Cisco devices in case we got trouble with the new IOS. Here’s what we do:

Cisco C870 Configuration

At this point, we had my 17-MB Cisco IOS on USB drive for our back up.

4>>>With the new IOS, plug it into your computer and copy it to USB drive and plug it to Cisco devices again. Using that command below to copy from USB drive to Cisco devices.
