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 Dening SNTP Global Settings
The SNTP Properties Page provides information for dening SNTP parameters globally.
To dene 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 elds:
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 —
Denes 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 — Denes 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 elds 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 — Denes 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 elds 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 — Denes 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. Dene the Poll Interval, Enable Receive Broadcast Servers Update, Enable Receive Anycast Servers Update, Enable
Receive Unicast Servers Update, and Enable Poll Unicast Servers elds and select at least one of the Enable elds.
3. Click . The SNTP global settings are dened, and the device is updated.
3.2.3 Conguring SNTP Authentication
The SNTP Authentication Page enables conguring the SNTP authentication method.
