server, the SNTP client listens for the response. The SNTP client neither sends time information requests nor receives responses from the Broadcast server.

Message Digest 5 (MD5) 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.

3.2.2 Defining SNTP Global Settings

The SNTP Properties Page provides information for defining SNTP parameters globally.

To define the SNTP global parameters:

1.Click System > System Info > SNTP > Properties. The SNTP Properties Page opens:

Figure 12: SNTP Properties Page

The SNTP Properties Page contains the following fields:

Poll Interval — Defines the interval (in seconds) at which the SNTP server is polled for Unicast information. The Poll Interval default is 1024 seconds.

Enable Receive Broadcast Servers Updates — Defines whether or not the device monitors the SNTP servers for Broadcast server time information on the selected interfaces. The possible values are:

Enable — Enables the device to receive Broadcast server updates.

Disable — Disables the device from receiving Broadcast server updates.

Enable Receive Anycast Servers Updates — Defines whether or not the device polls the SNTP server for Anycast server time information. If both the Enable Receive Anycast Servers Update and the Enable Receive Broadcast Servers Update fields are enabled, the system time is set according to the Anycast server time information. The possible values are:

Enable — Enables the device to receive Anycast server updates.

Disable — Disables the device from receiving Anycast server updates.

Enable Receive Unicast Servers Updates — Defines whether or not the device polls the SNTP server for Unicast server time information. If the Enable Receive Broadcast Servers Updates, Enable Receive Anycast Servers Updates, and Enable Receive Unicast Servers Updates fields are all enabled, the system time is set according the Unicast server time information. The possible values are:

Enable — Enables the device to receive Unicast server updates.

Disable — Disables the device from receiving Unicast server updates.

Enable Poll Unicast Servers — Defines whether or not the device sends SNTP Unicast forwarding information to the SNTP server. The possible values are:

Enable — Enables the device to receive Poll Unicast server updates.

Disable — Disables the device from receiving Poll Unicast server updates.

2.Define the Poll Interval, Enable Receive Broadcast Servers Update, Enable Receive Anycast Servers Update, Enable Receive Unicast Servers Update, and Enable Poll Unicast Servers fields and select at least one of the Enable fields.

3.Click Figure 12: SNTP Properties Page. The SNTP global settings are defined, and the device is updated.
