188 SNTP Client Configuration
SN(cfg)# sntp-client operating-mode multicast
21.5 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 SmartNode) 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 (SmartNode) using the same port number as used in the
request. The local port number is set to 123 by default.
Procedure
To define the local port number, which uses the SNTP client to contact the SNTP time server, unicast
