Exploring stacking x440 via sfp+ with x670v, is it possible?

Gene_Fontanilla — Mon, 26 Jan 2015 08:57:00 GMT

Is it possible to stack x440 with x670v, I'm planning to stack 2 x670v with 2 x440.

when I do "show stacking", the x670v shows that it detects the other x670v showing its mac-address. but not the x440.

I'm using v160 stacking on the x670v via VIM40G4X stacking module, and want to stack the x440 with the x440 using the sfp+ slot 49:50

As far as I know all SummitStack switches support stacking feature and you can stack them with each over.

Although you can mix Summit X440, X460, X480, X670, and X770 switches in a stack, we
recommend that you do not mix these switch types if the desired routing table exceeds the
supported limit for the Summit X460 switch, which is 12,256 IPv4 LPM routes.

Hi eyeV, thanks for this.

Is this on the Release Notes on the latest XOS?

This quote from the Concepts Guide for release 15.4.

Firstly I'm not sure that you can mix VIM ports with SFP+ ports. I haven't found anything about it in Concepts Guide. I'm just not sure about it. Secondly you should enable stacking support on SFP+ ports.

Something about it in Concepts Guide.

Also, while logged into each node, if you plan to use the SummitStack-V feature, configure the required alternate ports on that node or enable stacking-support as required

When the stacking-support option is enabled, data communications stops on the physical data ports listed in Support for Alternative Stack Ports on page 143. When stacking is enabled (with the enable stackingcommand), the stacking protocol for logical stack ports 1 and 2 operates on the physical data ports listed in this table.

I recommend to read Concepts Guide. It's really useful and well written guide.

You can build such a stack. The X670V would most likely use 40G ports for stacking, and you would use 10G to stack with x440-10G. The 10G ports on the x670V are alternate stacking port.

You should read the Summit Hardware Guide for details on how to connect the switches and build your switch, and User Guide for the config part.

Obviously, such a stack would bring some limitations due to the x440 scalability. I would encourage you to stay at L2 and put the x440 in standby role. Validate the scaling of the x440 is enough for the stack.

Thank you! I have stacked the switches!
