Simple Network Time Protocol
ProCurve 1810G switch software supports the Simple Network Time Protocol (SNTP). SNTP ensures
accurate network device clock time synchronization up to the millisecond. Time synchronization is
performed by a network SNTP server. The software operates only as an SNTP client and cannot provide
time services to other systems.
N o t e
SNTP acquires the Coordinated Universal Time (UTC) from an SNTP server. Configure the Time Zone
(see
page 3-4 ) and Daylight Savings Time (see page 3-5 ) to configure the offsets for your local time zone.
To display the SNTP page, click Network Setup > SNTP in the navigation pane.

Field Description
Enable SNTP Select to enable SNTP client mode. Clear to disable SNTP client mode. When disabled, the system
time increments from 00:00:00, 1 Jan 1970, which is set at bootup.
SNTP/NTP Server Specify the IP address of the SNTP server to send requests to.
Server Port Specify the server's UDP port to listen for responses/broadcasts (range 1–65535, default = 123).
Time Format Select either 24-hour (“military” time) format or 12-hour (standard) format.
Current Time/Date The switch-adjusted time and date when delivered by the time server.
Attempts The number of requests made to the SNTP sever since the switch was rebooted.
Last Failure The status of the last request to the SNTP server.
When this value is
SNTP Server Error , the server cannot send further updates. You can
reconfigure the SNTP server with a new server address to get time updates.
Failures The number of failed SNTP requests made to this server since last reboot.
