upgrading a stack

Andy White · ‎04-30-2012

Hi,

I just need a little refreshing on upgrading a stack of 3750's. This stack only has 2 switches:

Current

Switch# Role Mac Address Priority State

--------------------------------------------------------

1 Slave 0019.e6d6.fa80 10 Ready

*2 Master 0017.81de.8780 14 Ready

1.) If I remember correctly I simply tftp the IOS to the flash of each switch and then reload the master only?

2.) Can I safely assume these are the 2 flash locations:

3750-SW#sh flash?

flash2: flash:

I was expecting flash1 and flash2.

Thanks in advance for your help

Use the tar file:

have a look at this doc:

The firmware we are usign is c3750-ipbasek9-mz.122-55.SE5.bin can't we just use that? I'm pretty shure all I did we copy to the flash of each switch and relaoded the config?

I've never used a tar file before, I see that the tar file comes with express setup, what is this (c3750-ipbaselmk9-tar.122-55.SE5.tar)?

Thanks

If you are dealing with switch stacks, it's better to use the TAR file because you can run an automation script to un-pack (or un-zip) the TAR file into the correct folder.

In your case of two switches in a stack, it's as simple as using this command: archive download-sw /dest 1 /dest 2 tftp:///c3750-ipbaselmk9-tar.122-55.SE5.tar". Now if you want to delete the old IOS you can insert the toggle "/overwrite". And yes, you do want to delete the old IOS if either one of the switch in the stack has 16mb of flash memory.

The c3750-ipbaselmk9-tar.122-55.SE5.tar file is a unique file because it's designed for the 3750 with 16 mb of flash. The "l" suffix means it's a "lite" or an IOS pack in a diet.
