Simple Network Time Protocol (SNTP)
Overview
The SNTP implementation has the following features:
•
Used for synchronizing network resources
•
Adaptation of NTP
•
Provides synchronized network timestamp
•
Can be used in broadcast or unicast mode
•
SNTP client implemented over UDP that listens on port 123
CLI Examples
The following are examples of the commands used in the SNTP feature.
Example #1: Viewing SNTP Options
(Dell Routing)(Config) #sntp ?
console(config)#sntp ?
authenticate
Require authentication for received Network Time
Protocol (NTP) traffic from servers.
authentication-key
Define an authentication key for Simple Network
Time
Protocol (SNTP).
broadcast
Configure SNTP client broadcast parameters.
client
Configure the SNTP client parameters.
server
Configure SNTP server parameters.
trusted-key
Authenticate the identity of a system to which
SNTP will synchronize.
unicast
Configure SNTP client unicast parameters.
