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.

Enabling NTP Distribution

To enable NTP configuration fabric distribution, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# ntp distribute
switch(config)# no ntp distribute

Committing NTP Configuration Changes

When you commit the NTP configuration changes, the effective database is overwritten by the
configuration changes in the pending database and all the switches in the fabric receive the same
configuration. When you commit the NTP configuration changes without implementing the session
feature, the NTP configurations are distributed to all the switches in the fabric.
To commit the NTP configuration changes, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# ntp commit
