Cisco 3560 Switches

1. Tools Needed

CISCO 3560 switch, PC with Super Terminal installed, TFTP or FTP server, c3560-advipservicesk9-mz.122-25.SEE2.bin

2. Backup IOS

Use the dir, cd, pwd and other commands to see the directory structure in the flash before performing the backup. The bin file and html folder of this switch IOS are in the c3560-ipbase-mz.122-25.SEB4 directory in the flash.

2.1 Back up the original IOS to the TFTP server with IP

switch#copy flash:/c3560-ipbase-mz.122-25.SEB4/c3560-ipbase-mz.122-25.SEB4.bin

2.2 Back up the original IOS as a tar file to the TFTP server with IP address

switch#archive tar /create tftp://

3. Upload new IOS

Copy the new IOS to the root directory of the flash

switch#copy tftp://

(Note: If you are using CISCO-specific TFTP software, the TFTP software will be shut down immediately after running this command. In this case, you need to manually start the TFTP software again.)

4. Change the start up settings

4.1 Let the switch start with the new IOS

Switch(config)#boot system flash:/c3560-advipservicesk9-mz.122-25.SEE2.bin

4.2 Set up an alternate IOS boot

switch(config)#boot boothlpr flash:/c3560-ipbase-mz.122-25.SEB4/c3560-ipbase-mz.122-25.SEB4.bin

After rebooting, the switch will use the new IOS.Common questions: Switch IOS loading order issues.Switch IOS boot sequence: start help ios (boot boothlpr) --- help ios (boot helper) --- system ios (boot system)
