Horizontal Stacking is only supported on the Catalyst 1000 and 3560CX-12PD/3560CX-12TD.

Hello Leo,

Hi @Georg Pauwen,

Horizontal Stacking (for 3560CX-12PD/3560CX-12TD) or Single IP Management (Catalyst 1000) are just "rename" of the old technology called Switch Clustering (supported on 2900XL/3500XL, 2940/2950/2955/3550).  

Unfortunately Switch Clustering has been disabled due to security vulnerability:  Cisco IOS and IOS XE Software Cluster Management Protocol Remote Code Execution Vulnerability

Hello @Leo Laohoo 

I still try to use cluster for L2 RC connections on the old kit in our estates that for one reason or anohter cannot be replaced if/when we need to work one them, its dug me out a load of times, but unfortunaley as you said it is now a security vulenerabilty

Also ok i understand ..but i have other question ...

It is possible to configure etherchannel between three Switch 9200l and use cable RJ45 to have switch staking ??? 

Yes or no this proposition !!!

I wait a reply and thanks in advance

Hello,

you can use RJ-45 cables for Etherchannels between the switches, but not for stacking. As stated as an answer to your original post, you need StackWise cables and adapters for that.

Thanks to reply me

I don't understand your answer !!

My question . It is possible to have a Switch staking without use a cable staking !! Because i have 3 switch 9200l

So to have a switch staking ..i can use cable RJ45 between three Switch ??? Yes or not ?? Or i use cable staking for three Switch !!

I need answer for this question !!

Hello,

the answer is no. You need a StackWise cable and connect the 9200 switches using the StackWise adapters. RJ-45 is not possible.

As others have noted, for a 9200, no.

If it was a 9300 or 9400, stackwise virtual would be an option, I believe.
