X440-G2 port license upgrade


Userlevel 3
I am confused over the licence required to upgrade a X440-G2-48P-10GE4 switch , so that the 2 copper ports can run at 10G rather than IG , the document details to licence upgrades one for 4 ports and one for 2 ports which which is 16542. Basically I need too connect by 10Gig copper ( X670V-48T which I have in the core .

Thankd in advance

The X440-G2-48P-10GE4 does not support 10Gbase-T copper connections. The 10G license will allow you to use the SFP ports as 10G fiber ports. The 4 port license will allow all 4 to be used, while the 2 port will only allow 2 to operate at 10G (and the other two will be limited to 1G).

To connect this switch to an X670V-48t at 10G, you will need to use one of the 10G SFP ports on the X670V-48t, not one of the copper ports.

Hi Rod,

I checked into this, and it does look like the 2 copper 10Gbase-T ports should be covered under the 2 port 10G license.

You do not need the 10 gb license to support Summit stack -V to the X670. The nine switch models can support 10Gb stacking (SummitStack-V) across two of the 1Gb
SFP ports. These ports run a 10Gb stacking protocol by default so a 10GbE license is NOT required.

Hello, Rod!

But you have to remember that if you stack X440 with X670, stack performance will be based on X440 (FDB, LPM etc.).

Hi , I don't want to stack , I just need to understand that to change the copper from 1 gig to 10 gig , its the two port license , if anything they two port will be shared and I will run mlag at the other end between two existing X670V-48T units already in teh core ..

So my question is still teh same , with the 2 port licence this will upgrade the 2 copper from 1G
to 10G

The 10G Dual Lic ist alway for the shared 10G ports, if the device has 10G Copper (not all X440G2 10G devices have shared copper ports).
@Dana & Alexandr - Rod doesn't write that he want to stack...
btw... 10G Stacking via copper (RJ45) is not supported...

As I understand.



When you use dual-upgrade-license - it's for ports 51-52.
(because if you use Stack you don't need 4-upgrade-license)

So to use 10GBase-T you need dual-upgrade.

Thank you!
