CFS Distribution Modes

CFS supports three distribution modes to accommodate different feature requirements. Only one mode is
allowed at a given time.
• Uncoordinated distributions—Distribute information that is not expected to conflict with that from a
• Coordinated distributions—Distribute information that can be manipulated and distributed from multiple
• Unrestricted uncoordinated distributions—Allow multiple parallel distributions in the network in the

CFS Connectivity in a Mixed Fabric

CFS is an infrastructure component that also runs on the Cisco Nexus 7000 Series switches, Cisco Nexus
5000 Series switches, and Cisco MDS 9000 switches. A mixed fabric of different platforms (such as the Cisco
Nexus 9000 Series, Cisco Nexus 7000 Series, Cisco Nexus 5000 Series, and Cisco MDS 9000 switches) can
interact with each other.
Using CFSoIP, 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.
peer. Parallel uncoordinated distributions are allowed for an application.
devices (for example, the port security configuration). Coordinated distributions allow only one application
distribution at a given time. CFS uses locks to enforce this. A coordinated distribution is not allowed to
start if locks are acquired for the application anywhere in the network. A coordinated distribution consists
of three stages:
• A network lock is acquired.
• The configuration is distributed and committed.
• The network lock is released.
CFS can execute these stages in response to an application request without intervention from the
application or under complete control of the application.
presence of an existing coordinated distribution. Unrestricted uncoordinated distributions are allowed
to run in parallel with all other types of distributions.
