How to manage Network Time Protocol on Dell Networking Force10 Switches

Enabling NTP
NTP is disabled by default out of the box.
To enable NTP, specify an NTP server to which the Dell Networking system synchronizes. To specify multiple servers, enter the command multiple times. You may specify an unlimited number of servers at the expense of CPU resources.

Examples of Viewing System Clock

To display the system clock state about NTP, use the show ntp status command from EXEC Privilege mode.

Console(conf)#do show ntp status
Clock is synchronized, stratum 2, reference is 192.168.1.1
frequency is -369.623 ppm, stability is 53.319 ppm, precision is 4294967279
reference time is CD63BCC2.0CBBD000 (16:54:26.049 UTC Thu Mar 12 2009)
clock offset is 997.529984 msec, root delay is 0.00098 sec
root dispersion is 10.04271 sec, peer dispersion is 10032.715 msec
peer mode is client

Disabling NTP on an Interface
Once NTP is enabled globally, NTP is enabled on all active interfaces. If you disable NTP on an interface, Dell FTOS drops any NTP packets sent to that interface.
To disable NTP on an interface, use the following command.
