Cisco Cisco IOS Software Release 12.2(35)SE 릴리즈 노트

Before upgrading your switch software, make sure that you have archived copies of the current Cisco 
IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived 
images until you have upgraded all devices in the network to the new Cisco IOS image and until you 
have verified that the new Cisco IOS image works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more 
information:

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a 
host by using the copy flash: tftp: privileged EXEC command. 

You can also configure the switch as a TFTP server to copy files from one switch to another without 
using an external TFTP server by using the tftp-server global configuration command. For more 
information about the tftp-server command, see the “Basic File Transfer Services Commands” section 
of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at this URL:

This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a 
TFTP server and extract the files. You can download an image file and replace or keep the current image.

For downloading software, we recommend that you connect to the TFTP server through a network node 
interface (NNI). If you want to connect to the server through a user network interface (UNI), see the 
“Troubleshooting” chapter of the software configuration guide for methods for enabling ping capability 
on UNIs. See the 

 for a definition of NNIs and UNIs.
