NTP CFS Distribution
You can enable NTP fabric distribution for all Cisco MDS switches in the fabric. When you perform NTP
configurations, and distribution is enabled, the entire server/peer configuration is distributed to all the
switches in the fabric.
You automatically acquire a fabric-wide lock when you issue the first configuration command after you
enabled distribution in a switch. The NTP application uses the effective and pending database model to
store or commit the commands based on your configuration.
See to Chapter 13, “Using the CFS Infrastructure,” for more information on the CFS application.
This section includes the following sections:
• Configuring NTP with CFS, page 12-8
• Committing NTP Configuration Changes, page 12-9
