Send documentation comments to [email protected] 13 C H A P T E R Using the CFS Infrastructure The Cisco MDS NX-OS software uses the Cisco Fabric Services (CFS) infrastructure to enable efficient database distribution and to foster device flexibility. It simplifies SAN provisioning by automatically distributing configuration information to all switches in a fabric. Several Cisco MDS NX-OS applications use the CFS infrastructure to maintain and distribute the contents of a particular application's database. This chapter contains the following sections: • About CFS, page 13-1 • Disabling CFS Distribution on a Switch, page 13-4 • CFS Application Requirements, page 13-5 • Enabling CFS for an Application, page 13-5 • Locking the Fabric, page 13-6 • Committing Changes, page 13-7 • Discarding Changes, page 13-8 • Saving the Configuration, page 13-8 • Clearing a Locked Session, page 13-8 • CFS Merge Support, page 13-9 • Displaying CFS Configuration Information, page 13-9 • CFS Regions, page 13-16 • CFS Example Using Fabric Manager, page 13-20 • CFS Example Using Device Manager, page 13-23 • Default Settings, page 13-23 About CFS Many features in the Cisco MDS switches require configuration synchronization in all switches in the fabric. Maintaining configuration synchronization across a fabric is important to maintain fabric consistency. In the absence of a common infrastructure, such synchronization is achieved through manual configuration at each switch in the fabric. This process is tedious and error prone.
