NTP Configuration
The Network Time Protocol (
) is a protocol for synchronizing the time of different
network members. The devices that support NTP periodically exchange NTP packets to
synchronize their clocks.

9.1 Configuring NTP
The ZXA10 C300 works in NTP client mode and synchronizes its time with the NTP server.
Steps
1.
In global configuration mode, enable NTP.
ZXAN(config)#ntp enable
2.
Configure the NTP server.
ZXAN(config)#ntp server 1.2.1.1 priority 1
3.
Configure the source IP address of NTP packets for the time synchronization request.
ZXAN(config)#ntp source mng1
4.
Configure the alarm threshold of the NTP time synchronization offset value.
ZXAN(config)#ntp alarm-threshold 10
5.
Configure the NTP synchronization poll interval.
ZXAN(config)#ntp poll-interval 5
6.
(Optional) Query the NTP running status.
ZXAN(config)#show ntp status
Clock is unsynchronized , stratum 16, no reference clock
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**16
reference time is 0.0 (0)
clock offset is 0.00 msec, root delay is 0.00
msec
root dispersion is 0.00
msec, peer dispersion is 0.00 msec
server in use is 0:1.2.1.1
