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
client 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
• Anycast mode
• Enable - the SNTP client sends time synchronized broadcast packets to the network and
subsequently expects a reply from a valid timeserver. The client then uses the first reply it
receives to establish a link for future sync operations in unicast mode. This server will then
be added to the server association list. The client ignores any later replies from servers after
the first one is received.
The enabled anycast mode takes precedence over any entries currently in the associations
list when the sntpclient sync command is issued. The entry will then be substituted for any
existing entry in the unicast association list.
• Disable - stops synchronization via anycast mode.
If you choose the Unicast mode, you must set the dedicated unicast server for which the SNTP
client can synchronize its time. You can set the server either by specifying the IP address or the
hostname.
