Hi guys,

When use this command "configure stacking {node-address node-address | slot slot-number} license-level [core | advanced-edge | edge]"?

I read the manual but I didn't find any explanation.and examples.

Thanks in advance,

In certain stacking configurations there is sometimes a need to downgrade or equalize license levels among switches so they can be either a master or backup node.  This command allows you to set the license level per node or slot to an "effective" license.  An example would be if you stacked a X460-G2 to a X670-G2, out of the box a X460-G2 comes with edge and X670 comes with advanced edge.  You would either have to buy an advanced edge license for the 460 or issue the command on the 670 "configure stacking <node or slot #> license-level edge" (reboot) and you can now have in  effect two "edge" licenses to stack a master/backup. 

Make sense?

To add , one of the basic condition to build a  stack is , all slots need to have same license level.
This command helps restricting license in the slots to fulfill this condition.

Many Thanks,Syed

Thanks for the reply.

Is there any difference (new features / capacity / etc) using the command core or edge for example? 

I have 2x X450G2-48t-10G4 configured in stacking mode (Core Switch) and some X450-G2-48p-GE4 as Edge (Access Switch).

Hi Edson,

The licenses themselves are separate but related in regards to this command. The licenses allow certain capabilities whether it be core which allows the full capabilities of OSPF, EAPS, PIM etc as opposed to a edge license which is limited in its protocol use. So in a nutshell each switch needs its own separate license and the stacking command is used to limit the license level jsut for stacking purposes. As Bill mentioned in order to be a master-capable node the license has to match.

The license you need depends on how (for lack of a better term) complicated or robust you want to make the network. You can have a "core" switch jsut do standard routing and it would not require a core license. However if you would like to add multiple VLANs (More than 4, I believe) into OSPF it requires the core license.

I hope this helps and let me know if you need clarification.

Edson,

Whats the license level of your switches.  When you say (Core Switch) do you mean Core License?

Hi Stephen,

I said core switch because the 2x X450G2-48t-10G4 460-G2 are my core layer.
I haven't core license. :(

Thanks,

ok,  If both switches have the same license there is no need for the license-level command in stacking
