Configuring Cisco IOS Basics

2.5 Upgrading to a New Cisco IOS Release

Obtain new Cisco IOS features and more stable code by upgrading to a new Cisco IOS release.

Step 1

Display the contents of Flash memory:

5300-NAS#cd flash:

5300-NAS#dir

Directory of flash:/

1 -rw- 4541080 <no date> c5300-is-mz.113-7.AA

16777216 bytes total (12236072 bytes free)

5300-NAS#

Step 2

Copy the new image from the remote TFTP server into Flash memory. Make sure to specify your own

TFTP server’s IP address and Cisco IOS file name. In this example, Flash memory is erased before the

new image is downloaded. To see the bangs (!) during the download operation, you must have line wrap

enabled in your terminal emulation software.

Timesaver

Leave both images in Flash memory if you have the available space. If needed, you can

easily revert back to the previous image. Enter the

boot system flash

newiosname.bin

command to point to the new image file name. By default, the first image in Flash memory

is loaded.

5300-NAS#copy tftp: flash:
