Setting the System Clock
– 87 –
Configuring
Time Servers
Use the System > Time (Configure Time Server) pages to specify the IP address for
NTP/SNTP time servers, or to set the authentication key for NTP time servers.
Specifying SNTP Time Servers
Use the System > Time (Configure Time Server – Configure SNTP Server) page to
specify the IP address for up to three SNTP time servers.
Parameters
The following parameters are displayed:
◆ SNTP Server IP Address / Host Name – Sets the IPv4 address for up to three
time servers. The switch attempts to update the time from the first server, if this
fails it attempts an update from the next server in the sequence.
Web Interface
To set the SNTP time servers:
1. Click System, then Time.
2. Select Configure Time Server from the Step list.
3. Select Configure SNTP Server from the Action list.
4. Enter the IP address of up to three time servers.
5. Click Apply.

Specifying NTP Time Servers
Use the System > Time (Configure Time Server – Add NTP Server) page to add the IP
address for up to 50 NTP time servers.
Parameters
The following parameters are displayed:
◆ NTP Server IP Address – Sets the IPv4 address for up to three time servers. The
switch will poll the specified time servers for updates when the clock
maintenance type is set to NTP on the System > Time (Configure General) page.
