> # CFS Connectivity in a Mixed Fabric

> CFS is an infrastructure component that also runs on the Cisco Nexus 5000 Series switches and the Cisco MDS 9000 switches. A mixed fabric of different platforms (such as the Cisco Nexus 7000 Series, Cisco Nexus 5000 Series, and Cisco MDS 9000 switches) can interact with each other.

> Using CFSoIP and CFSoFC, the respective CFS clients can also talk to their instances running on the other platforms. Within a defined domain and distribution scope, CFS can distribute the client’s data and configuration to its peers running on other platforms.

> All three platforms support both CFSoIP and CFSoFC. However, the Cisco Nexus 7000 Series and Cisco Nexus 5000 Series switches require an FC or FCoE plugin and corresponding configuration in order for CFSoFC to operate. Both options are available by default on the Cisco MDS 9000 switches.

> Note Some applications are not compatible with their instances running on different platforms. Therefore, Cisco recommends that you carefully read the client guidelines for CFS distribution before committing the configuration.

> For more information on CFS for the Cisco Nexus 5000 Series and Cisco MDS 9000 switches, see the Cisco Nexus 5000 Series NX-OS System Management Configuration Guide and the Cisco MDS 9000 Family NX-OS System Management Configuration Guide, respectively.
