Configure System Information

GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches

4. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard

port (123), specify the port number.

5. In the Priority field, specify the order in which to query the servers.

The SNTP client on the device continues sending SNTP requests to different servers until

a successful response is received or all servers are exhausted. The request is sent to an

SNTP server with a priority value of 1 first, then to a server with a priority value of 2, and

so on. If more than one server has the same priority, the SNTP client contacts the servers

in the order that they appear in the table.

6. In the Version field, specify the NTP version running on the server.

7. Click the Add button.

8. Repeat the previous steps to add additional SNTP servers.

You can configure up to three SNTP servers.

The SNTP Server Status table displays status information about the SNTP servers

configured on your switch. The following table describes the SNTP Global Status fields.

Table 7. SNTP server status fields

Field Description

Address Specifies all the existing server addresses.

Last Update Time Specifies the local date and time (UTC) that the response from this server

was used to update the system clock.

Last Attempt Time Specifies the local date and time (UTC) that this SNTP server was last

queried.

Last Attempt Status Specifies the status of the last SNTP request or unsolicited message for both

unicast and broadcast modes. If no message has been received from a

server, a status of Other is displayed. These values are appropriate for all

operational modes:

• Other. The status of the last request is unknown, or no SNTP responses

have been received.

• Success. The SNTP operation was successful, and the system time was

updated.

• Request Timed Out. After an SNTP request was sent to an SNTP

server, the response timer expired before a response from the server was

received.

• Bad Date Encoded. The time provided by the SNTP server is not valid.

• Version Not Supported. The SNTP version supported by the server is

not compatible with the version supported by the client.

• Server Unsynchronized. The SNTP server is not synchronized with its

peers. This is indicated by the leap indicator field on the SNTP message.

• Server Kiss Of Death. The SNTP server indicated that no further

queries were to be sent to this server. This is indicated by a stratum field

equal to 0 in a message received from a server.
