interconnecting cat 3750 x stack and 3560g poe switch

                   Hi,

What are the options avilable to add a cat3560 g switch  to a stack of 3750x switches.?is there a connector avilable ?or is it possible to trunk via fiber ? cat 3560 has 4 sfps and 224 10/100/1000 ports with poe. cat 3750 stack has a 10 gb up link . What are the possible options?

Hi Prakavi,

The 3560 series switches can not be stacked. They don't have the stacking cable connections in the back of the chassis.

So, the only way you can connect a 3560 to a 3750 is by using a copper port or one of the fiber ports.  3560G comes only with 1Gig SFPs for uplink (no 10Gig capabilities), however 3560X comes with 1Gig or 10Gig capabilities. So, if you have a 3750X and a 3560X, you can connect them via 1Gig fiber or 10Gig fiber.  The only difference between the 3560X series and 3750X series is that the 3560X can not be stacked, everything else is the same.

Hi Prakavi,

Yes, you can trunk them together using fiber or copper.  If you have the budget, yes, I would replace the 3560G with 3750X.

The 3750X series can be stacked together.  If you are using POE, you can even stack the power together, 3750X has an out of band management port and also much more throughput with 1Gig and 10Gig capabilities.

Hi Reza,

so we can trunk a catalyst 3560g switch to a3750 stack either two copper ports on the switch or tusing one fo the fiber ports.We have some catalyst 3560 g switches  in some floors .I was just thinking whether t his can be utilized since these switches are 10/100/1000  and poe .only difference is the problem in up link.

Do you think is it better to replace 3560 g switches also with 3750x ?

Like my response to one of your post, please DO NOT be tempted to stack seven or more 3750/G/E/X in a single logical unit.

Posting

Just to add to what the other posters have noted, if you want to continue to use your 3560G, to avoid using your PoE ports for uplinks, your SFP ports, I believe, will also support copper (via SFPs).

Besides trunking, you also have the option of Etherchannel.  Dual Etherchannel, with links to different 3750X stack members, improves both your redundancy and makes more bandwidth available between the 3750X stack and your 3560G.  (NB: if the 3560G is only hosting "normal" user hosts and/or VoIP phones, likely 2 gig uplink bandwidth will be fine, if hosting bandwidth intensive hosts, e.g. server, you might want to consider more links for Etherchannel.)
