Information About CFS

Some features in the Cisco Nexus 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 to discover feature capabilities in all CFS-capable
switches.
Cisco Nexus Series switches support CFS message distribution over Fibre Channel and IPv4 or IPv6 networks.
If the switch is provisioned with Fibre Channel ports, CFS over Fibre Channel is enabled by default while
CFS over IP must be explicitly enabled.
CFS provides the following features:
• Peer-to-peer protocol with no client-server relationship at the CFS layer.
• CFS message distribution over Fibre Channel and IPv4 or IPv6 networks.
• Three modes of distribution.
