Patton electronic SmartNode 4110 Series manual Defining Sntp local UDP port

SmartWare Software Configuration Guide 26 • SNTP client configuration

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

Defining SNTP local UDP port

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.

Note 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

Step Command Purpose

1node(cfg)# sntp-clientlocal-portnumber 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.

Example: Defining the local UDP port for SNTP

Configures the SNTP client UDP port number to 123

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