Cisco 3400-ME, No boot system command available in configuration file

[Ha Dao]

Dear everyone

I have a Cisco switch 3400-ME, it's running IOS1.bin file. Now i want to change the running IOS to IOS0.bin

I entered 2 commands:

boot system flash:dir1/IOS0.bin

boot system flash:dir1/IOS1.bin

But when i show running config, it has no any boot system commands.

I'm confuse that what happen when i relboot that switch ??

But when i show running config, it has no any boot system commands.

The correct command to show the boot variable is "sh bootvar".

Tks but that command seems to be not working for me. I only can take the "sh boot" command

Sw-cus2-3400#show bootvar

Sw-cus2-3400#show boot
