Using Cisco Fabric Services
Cisco Nexus 5000 Series switches provide Cisco Fabric Services (CFS) capability, which simplifies
provisioning by automatically distributing configuration information to all switches in the network.
Switch features can use the CFS infrastructure to distribute feature data or configuration data required
by the feature.

Information About CFS

Some features in the Cisco Nexus 5000 Series switch require configuration synchronization with other
switches in the network to function correctly. Synchronization through manual configuration at each
switch in the network can be a tedious and error-prone process.
Cisco Fabric Services (CFS) provides a common infrastructure for automatic configuration
synchronization in the network. It provides the transport function and a set of common services to the
features. CFS has the ability to discover CFS capable switches in the network and discovering feature
capabilities in all CFS capable switches.
Cisco Nexus 5000 Series switches support CFS message distribution over Fibre Channel, IPv4 or IPv6
networks. If the switch is provisioned with Fibre Channel ports, CFS over Fibre Channel is enabled by
default. CFS over IP must be explicitly enabled.
CFS provides the following features:
