Configuring Network Time Protocol

Configuring NTP is a one-step process:

1. Enable NTP.

Enable NTP
NTP is disabled by default. To enable it, specify an NTP server to which the Dell Force10 system will
synchronize. Enter the command multiple times to specify multiple servers. You may specify an unlimited
number of servers at the expense of CPU resources.
