Configure SNTP client mode
1. Select an SNTP Synchronization mode(s): This action 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:
a. Unicast mode:
• Enable - this 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.
b. Broadcast mode:
• Enable - allows the SNTP client to accept time synchronization broadcast packets
from an SNTP server located on the network, and updates the local system time
accordingly.
• Disable - stops synchronization via broadcast mode
c. 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
