Specifying Which NTP Server a C-series Controller Contacts on Startup
When you boot a C-series Controller, it issues an
ntpdate
request, which polls a network server to determine the local date and time. Configure a server that the system uses to determine the time when the system boots. Otherwise, NTP cannot synchronize with a time server if the server's time is very far off the local system's time.To configure the NTP boot server:
- From configuration mode, access the configuration statement that configures NTP.
[edit]user@host#edit system ntp
- Specify the address or hostname of the network NTP server.
[edit system ntp]user@host#set boot-server
address
[edit system ntp]user@host#set boot-server 192.0.2.20
