Configuring NTP

You can configure NTP using either IPv4 addresses, IPv6 addresses, or Domain Name Services (DNS)
names. To configure NTP associations, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# ntp server
{ip-address | ipv6-address |
dns-name}
Step 3
switch(config)# ntp peer {ip-address
| ipv6-address | dns-name}
Step 4
switch(config)# exit
Step 5
switch# copy running-config
startup-config
Step 6
switch# show ntp peers

NTP CFS Distribution

You can enable NTP fabric distribution for all Cisco Nexus 5000 Series switches in a fabric using the
Cisco Fabric Services (CFS). When you perform NTP configurations, and distribution is enabled, the
entire server or peer configuration is distributed to all the switches in the fabric.
You automatically acquire a fabric-wide lock when you enter the first configuration command after you
enabled distribution in a switch.The NTP application uses an effective and pending database model to
store or commit the commands based on your configuration. You changes are stored in the pending
database and committed to the effective database.
