Is extended fabric licence needed on all switches?

Hi,

We will be deploying 4 switches (2 per site) over WDM with distance of 200Km 1Gb/s. In my notes it says that we need this for BB credit of 250 or more for 2 ports.

Will all this be covered by buying 4 extended fabric licenses and 8 x 4Gb 10Km FC SFP?

Hello,

you need the license on each switch, that is connected to the WDM link. If the link is only between two switches, you only need two licenses. Are all four switches connected to the WDM link, you need four licenses.

You don't need the long wave SFPs. These SFPs are only used if you have a direct connect, but you use WDM. So your switches are connected to a (hopefully) supported 3rd party WDM product.

Regards,
Patrick
