Note The Cisco 12006 Router is based on a 2.5-Gbps switch fabric, where each SFC or CSC provides a 2.5-Gbps full-duplex connection to each line card in the system. The 2.5-Gbps switch fabric consists of the 12006 Advanced Clock and Scheduler Card (product number 12006-CSC=) and the 12006 Advanced Switch Fabric Card (product number 12006-SFC=).

The Cisco 12406 Router is based on a 10-Gbps switch fabric, where each SFC or CSC provides a 10-Gbps full-duplex connection to each line card in the system. The 10-Gbps switch fabric consists of the Clock and Scheduler Card (product number GSR6-CSC=) and the Switch Fabric Card (product number GSR6-SFC=).

You cannot mix 2.5-Gbps switch fabric cards and 10-Gbps switch fabric cards in a chassis. The router will not operate with a mix of switch fabric card types.
