Stack question

Hello,

I have a stack of 4 3750G which all have 24 ports.  I need to buy another switch as we are running out of ports can i add a 48 port version of the switch, or do they all have to be the same?

Thanks

Re: Stack question

Hi Andy-

You can add the 48 port switch. You need to make sure that it is the same major IOS version as your 24 port switches. Here's a helpful link.

http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst3750/software/release/12.2_25_see/configuration/guide/swstack.html

I also suggest that you provision it so nothing gets messed up. The directions on how to do that are in the link above.

Hope it helps.

Here is my current spec on the switches in the stack, what am I looking for?  I guess I need a WS-C3750G-48T-S and use the firmware c3750-ipbase-mz.122-53.SE.bin :

Re: Stack question

Hello,

Use this URL (I've just removed the "/partner/" component of the URL as that one requires login while the one I am providing now is simply the same content just without requiring any logging in):

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_25_see/configuration/guide/swstack.html

Best regards,

Peter

Re: Stack question

Sorry about the URL. Cisco's site randomly logs me in and out. When I went to get the URL I looked and it did not have me logged in so I assumed it never logged me in, but I guess it did.

Re: Stack question

Thanks, great doc.  Basically as log as provision them properly like I have before I should be fine I guess.  All our switches are WS-C3750G-24T-S so if I get the WS-C3750G-48T-S and use the same IOS that they are using which is 12.2(53)SE - C3750-IPBASE-M?

one of the stacks:

Switch Ports Model              SW Version            SW Image

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

*    1 24    WS-C3750G-24T      12.2(53)SE            C3750-IPBASE-M

     2 24    WS-C3750G-24T      12.2(53)SE            C3750-IPBASE-M

Thanks in advance for your advise.
