Hi, does anyone know what is this CRS-1 MSC 20G card (prod number CRS-MSC-20G_? I understand that they have a MSC 40G with two SPP processors, one per direction (ingress/egress). But there is an option to buy a 20G version of this card. Is this done through licensing or is the 20G card a different HW card alltogether? Thanks, Marlon
