SNTP client configuration task list

SmartWare Software Configuration Guide 

Example: Configuring SNTP client operating mode 

Configures the SNTP client operating mode to unicast operation

node(cfg)#sntp-client operating-mode unicast

Configures the SNTP client operating mode to anycast operation 

node(cfg)#sntp-client operating-mode anycast

Configures the SNTP client operating mode to multicast operation 

node(cfg)#sntp-client operating-mode multicast

The communication between an SNTP client and its the primary or secondary SNTP time server uses UDP. 
The UDP port number assigned to SNTP is 123, which should be used in both the source port (on the Smart-
Node) and destination port (on SNTP time server) fields in the UDP header. The local port number, which 
the SNTP client uses to contact the primary or secondary SNTP time server in unicast mode, has to be 
defined. 

The local port number setting is used when contacting the SNTP time 
server. The SNTP time server will send its reply to the SNTP client (Smart-
Node) using the same port number as used in the request. The local port 
number is set to 123 by default.

This procedure describes how to define the local port number, which uses the SNTP client to contact the 
SNTP time server, unicast mode

Mode: Configure

Example: Defining the local UDP port for SNTP 

Configures the SNTP client UDP port number to 123

node(cfg)#sntp-client local-port 123

Specifies the SNTP local UDP port number. The port 
number can be defined in the range from 1 to 
65535. The UDP port number assigned to SNTP is 
123.
