Updating IOS with or without web based dev mgr

[Fabri_Fabri]

Need to update IOS firmware on 2960 and 3560 and I wonder if upgrade process is different using the image with "WEB BASED DEV MGR".

I did a few upgrade with the BIN image without web based dev mgr and all worked well.

Instead, I noticed that a TAR file is downloaded if I choose the WEB BASED DEV MGR version.

Is the upgrade process different or I just upload TAR image to the switch and all the rest is the same ?

Thanks.

BIN and TAR update processes are different.  The latter needs to be unpacked, and the latter's process can do a stack (at least on 3750s).

Hi Joseph and thanks for reply.

If I unpack TAR file I can see a folder with a bin file and a bunch of html/js/css files (that pretty much are the web console, I think).

Regarding BIN update process I usually do the following:

1) copy tftp flash:

2) no boot system

3) boot system flash:<file>.bin

4) wr mem

5) reload

In what TAR update is different ?

Thanks.

There's a CLI command for updating the device with a TAR file.  Besides unpacking the TAR, which you can do manually too (as you've done), it will update the bootvar and if you were doing the command on a 3750 stack, it would update other stack members too.

The CLI command has some options, such as keeping the current image on the system or not, etc.

The TAR image also often has a Web manager too, which I don't believe is ever found in the BIN image.
