Cisco Fabric Services (CFS) capability simplifies provisioning by automatically distributing configuration information to all switches in the network.

Nexus Switch features can use the CFS infrastructure to distribute feature data or configuration data required by the feature.

cisco fabric services (CFS) synchronize the features between devices under the same region. By default, All devices begin in the same region, and this region is called the default region.

To create new region:

# cfs region 100

CFS configuration example:

conf terminal

cfs ipv4 distribute

ntp distribute

ntp commit

with this configuration in place, NTP will be configured in all nexus devices with the same region.
