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
Client Mode
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.
Port
Specifies the local UDP port to listen for responses/broadcasts. Allowed range
is (1 to 65535). Default value is 123.
Unicast Poll Interval
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.
Broadcast Poll Interval
Specifies the number of seconds between broadcast poll requests expressed
as a power of two when configured in broadcast mode. Broadcasts received
prior to the expiry of this interval are discarded. Allowed range is (6 to 10).
Default value is 6.
