Connecting two Cisco 3560G Switches with a SFP module

Hello,

I have two 3560G, 48 port switches I would like to connect together as "one" using an SFP connector.  One of the switches is already programmed with an IP address, password, vlans, etc.  The other switch is brand new in the default state.

I would like to utilize port g0/49 on both switches for the SFP cable.

What are the steps and Actual commands necessary to create "one" switch with the SFP cable?  I am new at Cisco commands, so details would be great! Thank you in advance!

Re: Connecting two Cisco 3560G Switches with a SFP module

Your requirement is not supported on the 3560G switch line.

You need a stackable solution such as 2960-S or 3750 in order to convert 2 physical switches into one logical switch.

Re: Connecting two Cisco 3560G Switches with a SFP module

What you are asking about is using Switch Clustering:

https://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_25_see/configuration/guide/swclus.html

This technology replicates the behavior of 3750 switch clustering, contrary to the comment by Edison.

I hope this helps, please rate if it does.

Regards,
Tim
