How to get a 3560 Switch to run from new conf file on reload

[Jay Matrona]

Hi All,

I uploaded a new config file via TFTP to a 3560 switch.  What are the order of commands to get it to boot from this new config file instead of the file listed in 'sh boot':

Directory of flash:/

Do I just do a copy flash:uswal-sw6-confg start  and reboot switch?

Hi,

.

Just do a copy tftp://x.x.x.x start and reload and it should work.

Regards.

Alain.

There's a couple of methods you could use.

Be warned - if this new config file is not right, you could lock yourself out of the switch and have to get back in via the console.

You could issue the following command

copy flash:uswal-sw6-config startup-config

Or you could do this

delete flash:config.text

rename flash:uswal-sw6-config flash:config.text

then reload the switch (in either case).

If there's something not quite right in the new config,e specially in the management IP configuration, then you will have to console in via the serial port and rectify the problems.

Cheers.

Thanks for the info guys!  One more question

Does it matter that the config I am going to use is from a Fast Ethernet switch and this one is a Gigbit??

Both are 3560 series PoE switches with same # of interfaces

[milan.kulik]

Hi,

sure it does matter!

The switch would ignore all commands for incorrect (FastEthernet) interfaces.

So at least you should replace all FastEtherent interface names with Gigabitethernet ones.

And still you are risking some commands might not be supported while other missing.

Is it such a problem to modify the curent running config the way you need?

HTH,

Milan

Heck yes!

All your interface definitions will be wrong (the names, if not the numbers), and there may be other issues as well.

If you can't change the configuration in-situ, I suggest you do the following.

Logon to the switch and capture the existing configuration - you can either just do something like

term length 0

show running-config

and capture the output, or you can do

copy running-config tftp:

if you have a tftp server available.

Then modify the configuration you captured, and upload it back before doing the rename/reload trick.

As Milan said - is there some reason you can't just modify the configuration online to get the result you want?

Cheers

Thanks to everyone for their help on this.  I decided to modify the existing config and not take any chances.  I thought that the using the other config file would be the quicker and more painless way to get this replacement switch up and running....
