5.3.3.1.7 SNTPCLIENT SET MODE

Syntax

SNTPCLIENT SET MODE {UNICAST|BROADCAST|ANYCAST} {ENABLE|DIS-

ABLE}

Description

This command enables/disables the STNP client in a particular time synchronous access

mode. There are three modes to choose from, and each mode has enable and disable

options:

Unicast mode

•

Enable

the mode uses a unicast server and the IP address or hostname in the SNTP server

association list is used to synchronize the client time with the server. The SNTP cli-

ent attempts to contact the specific server in the association in order to receive a

timestamp when the

SNTPCLIENT SYNC COMMAND

is issued.

•

Disable

the unicast server is removed from the association list.

Broadcast mode

•

Enable

allows the SNTP client to accept time synchronization broadcast packets from an

SNTP server located on the network, and updated the local system time accordingly.

•

Disable

stops synchronization via broadcast mode
