Stacking a 3050G

Hi,

We are using a Cisco 3750G 24 port switch, I want to make it 48 ports so I am going to buy a new one and stack it.  Does the firmware version/age on both have to be the same?

Thanks

Yes, the IOS has to be the same on both switches.

When you get the new switch make sure you load the same IOS as the exiting one you have before stacking them together.

Also be sure to give the switch you want as a master a higher priority. priority 1 is the lowest and 15 is the highest.

Please follow the config guide below for adding and removing switches to your stack.

Good luck

Thanks, I've stack before, but they have always been the same IOS out of the box.

My current switch is this:

3750-A#sh flash

Directory of flash:/

    2  -rwx        4755   Aug 6 2009 08:43:19 +01:00  config.text

    3  -rwx         616  Mar 29 1993 03:51:16 +01:00  vlan.dat

    5  drwx         192   Mar 1 1993 00:06:55 +00:00  c3750-ipbase-mz.122-35.SE5

  509  -rwx           5   Aug 6 2009 08:43:19 +01:00  private-config.text

15998976 bytes total (6364672 bytes free)

Is 192 the size of the IOS? looks like I only have 6.3mb free.

Yes, you only have 6.3mb free left.

I just checked the size of the c3750e-ipbasek9-mz.122-50.SE2.bin is 10.4 MB (10,948,510 bytes)

So, you have to use c3750-ipbase-mz.122-35.SE5 on your new switch too to match this one.

Re: Stacking a 3050G

1.) What is taking all the space up?

2.) Looks like I have 16mb of Flash?  Can I not delete the current IOS then install the new one?

3.) How can I chekc the size of the current IOS in the flash, it just says 192?

Andy,

You can delete the current version and install newer IOS while the box is running.  Then when you reboot you will see new IOS version

Re: Stacking a 3050G

If you look at your display what you are looking at is not the IOS file it is a directory name which happens to be part of the actual imagename  . Notice the .bin is missing and the file has a "DRWX" in front of it which means a directory .  The actual .bin file and all the html files are inside that directory  and thats whats taking up all your space . 3750's only have enough enough room for 1 image , you will have to delete that directory before adding a new image .   If you need a gui interface you will have to use a .tar file if not use the standard .bin file .   If you do a show boot command you will see it is  directoryname/imagename  such as 

c3750-i5-mz.122-20.SE/c3750-i5-mz.122-20.SE.bin
