Item Description
SNMP Server Port The UDP port number on which the SNMP server listens for requests.

communicating with the device until the client applications are recon-
figured to use the new port number.

Item Description
Client Mode Specifies the mode of operation of SNTP Client. An SNTP client may
operate in one of the following modes:

Disable: SNTP is not operational. No SNTP requests are sent
from the client nor are any received SNTP messages pro-
cessed.

Unicast: SNTP operates in a point-to-point fashion. A unicast cli-
ent 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.
Unicast Poll Interval
(Seconds) Specifies the interval, in seconds, between unicast poll requests
expressed as a power of two when configured in unicast mode.
Broadcast Poll Inter-
val (Seconds) Specifies the interval, in 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.
