Configuring the Source IP Address for NTP Packets: Example
The following example shows an NTP configuration in which Ethernet management interface 0/0/CPU0/0 is
configured as the source address for NTP packets:
ntp
authentication-key 2 md5 encrypted 06120A2D40031D1008124
authentication-key 3 md5 encrypted 1311121E074110232621
authenticate
trusted-key 3
server 10.3.32.154 key 3
peer 10.32.154.145 key 2
source MgmtEth0/0/CPU0/0
Configuring the System as an Authoritative NTP Server: Example
The following example shows a NTP configuration in which the router is configured to use its own NTP
master clock to synchronize with peers when an external NTP source becomes unavailable:
ntp
master 6
Updating the Hardware Clock: Example
The following example shows an NTP configuration in which the router is configured to update its hardware
clock from the software clock at periodic intervals:
ntp
server 10.3.32.154
update-calendar
