Switch Stacks

[frankamankwah1]

Hi,

We already have a couple of WS-C3750-48PS-S stacked together on our LAN. Would it be possible to add WS-C3750V2-48PS-S to the stack without encountering any issues. I intend to use the same IOS version and feature sets.

Thanks

Hello,

You can certainly add another switch to the stack without any issues. Please

follow the proper procedure while adding the new switch to the stack.

-- Turn off the new switch

-- Make appropriate connections

-- Turn on the new switch

That should address this issue.

Hope this helps.

Regards,

NT

Hello Frank,

Yes it would be possible :

Cisco StackWise technology unites up to nine  individual switches in a single logical unit, using special  stack-interconnect cables and stacking software. The individual switches  can be any combination of Cisco Catalyst 3750, 3750 v2, and 3750-E  Series Switches.

There should be no problem as longer as we follow the general conditions and restrictions of managing stacking =>

I think also we have to be careful of this bug imacting some recent IOS releases (12.2(53)SE2        .....):

C3750V2 stack ports going down after IOS upgrade

Symptom: Stack ports are flapping continously or some of them stay down. Conditions: This has been observed on WS-C3750V2-48PS and WS-C3750V2-24PS switches after upgrading to 12.2(53)SE2. Workaround: Downgrading to IOS 12.2(52)SE or older solves the issue completely.

Hope it helps.

Kind regards
