Updating the Appliance Clock

The CCM appliance supports the NTP protocol. When NTP is enabled, the real time clock on the CCM appliance will be updated immediately after NTP is enabled, each time the appliance reboots and optionally, at specified intervals.

You may specify one or two NTP servers to provide the time. An NTP server may be external or an internal server that you supply. The primary server will be queried for the time first. If it does not respond with a valid time, the secondary server will be queried.

To enable or disable NTP:

To enable NTP, issue an NTP command with the Enable parameter.

NTP ENABLE [IP=<prim_add>[,<sec_addr>]] [UPDATE=<hours>]

If this is the first time NTP is being enabled, you must specify at least one NTP server address.

If you want the time to be updated periodically, specify an update interval of up to 99 hours. If you specify a zero interval value (which is the default), the time will be updated only when the CCM appliance reboots.

When you enable NTP, you are prompted to confirm or cancel the operation. To disable NTP, issue an NTP command with the Disable parameter.
