Protocol Overview
The NTP messages to one or more servers and processes the replies as received. The server interchanges addresses and ports,
fills in or overwrites certain fields in the message, recalculates the checksum, and returns it immediately.
Information included in the NTP message allows each client/server peer to determine the timekeeping characteristics of its
other peers, including the expected accuracies of their clocks. Using this information, each peer is able to select the best time
from possibly several other clocks, update the local clock, and estimate its accuracy.

Implementation Information
Dell Networking systems can only be an NTP client.
Configure the Network Time Protocol
Configuring NTP is a one-step process.
● Enabling NTP
Related Configuration Tasks
● Configuring NTP Broadcasts
● Disabling NTP on an Interface
● Configuring a Source IP Address for NTP Packets (optional)
Enabling NTP
NTP is disabled by default.
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.
