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:
• Peer-to-peer protocol with no client-server relationship at the CFS layer.
• CFS message distribution over Fibre Channel, IPv4 or IPv6 networks.
• Three modes of distribution.

◦ Coordinated distributions: Only one distribution is allowed in the network at any given time.
◦ Uncoordinated distributions: Multiple parallel distributions are allowed in the network except when
a coordinated distribution is in progress.
