Description |
|---|---|
|
auth-key-id |
Defines the NTP authentication key identifier (string) for authenticating NTP messages. |
|
auth-key-md5 |
Defines the authentication key (string) shared between the device (client) and the NTP server, for authenticating NTP messages. |
|
enable |
Enables the device to synchronize its local clock (date and time) with an NTP server. |
|
ntp-as-oam {off|on} |
Defines the location of the Network Time Protocol (NTP). |
|
ntp-network-interface |
Assigns an IP Interface from the IP Interfaces table for NTP communication. |
|
primary-server |
Defines the NTP server FQDN or IP address. |
|
secondary-server |
Defines the NTP secondary server FQDN or IP address. |
|
update-interval |
Defines the NTP update time interval (in seconds). The value must be a multiple of 60 (seconds). For example, to set an interval of 2 hours, configure the parameter to 7200 (i.e., 2 hours is 7200 seconds). If the value is not a multiple of 60, the device automatically rounds it to the nearest multiple of 60 and logs this adjustment in a syslog message. For example, if you enter 7195, the device rounds it to 7200. |
