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 IPv4 or IPv6 networks.
CFS provides the following features:
-
Peer-to-peer protocol with no client-server relationship at the CFS layer.
-
CFS message distribution over IPv4 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.
-
Unrestricted uncoordinated distributions—Multiple parallel distributions are allowed in the network in the presence of an existing coordinated distribution. Unrestricted uncoordinated distributions are allowed to run in parallel with all other types of distributions.
-
The following features are supported for CFS distribution over IP:
-
One scope of distribution over an IP network:
-
Physical scope—The distribution spans the entire IP network.
