tsclockserver tsclockserver Displays or sets the NTP Server address. Synopsis tsclockserver [ipaddr] Availability All users (display). Admin (set). Release V3.1.x and V4.1.x Description Use this command to synchronize the local time of the Principal or Primary FCS switch to an external NTP server. The Time Server daemon synchronizes fabric time by sending updates of the Principal or Primary FCS local switch time periodically to every switch in the fabric. The Time Server daemon runs on all switches in the fabric, but only the Principal switch (when the Security feature not enabled), or the Primary FCS switch (when the Security feature is enabled) connect to the NTP server, and broadcast Time Service updates. All switches in the fabric maintain the current clock server IP address in non-volatile memory. By default this value is "LOCL." Changes to the clock server IP address on the Principal or Primary FCS switch are propagated to all switches in the fabric. Use this command with no parameters to display the current clock server IP address being used. Specify the ipaddr operand to set the clock server IP address, and enable fabric wide clock synchronization with the specified clock server. Fabric OS Version 3.1.x/4.1.x Reference Guide 861
