MD5 (Message Digest 5) Authentication safeguards device synchronization paths to SNTP servers. MD5 is an algorithm that
produces a 128-bit hash. MD5 is a variation of MD4, and increases MD4 security. MD5 verifies the integrity of the
communication, authenticates the origin of the communication.

Description
Use drop-down list specify the SNTP client mode, which is one of the following modes:
• Disable: SNTP is not operational. No SNTP requests are sent from the client nor are
any received SNTP messages processed.
• Unicast: SNTP operates in a point to point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally the round-trip delay and local clock offset relative
to the server.
• Broadcast: SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address has a
single subnet scope while a multicast address has Internet wide scope.
Specifies the local UDP port to listen for responses/broadcasts. Allowed range is (1 to
65535). Default value is 123.
Specifies the number of seconds between unicast poll requests expressed as a power
of two when configured in unicast mode. Allowed range is (6 to 10). Default value is 6.
