address is a DNS host name, then that host name is resolved into an IP address each
time an SNTP request is sent to it.
8. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard
port (123), specify the port number in the Port field.
The range is from 1 to 65535. The default value is 123.
9. In the Priority field, specify the priority order 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 priority indicates the
order in which to query the servers. 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 any servers are
assigned the same priority, the SNTP client contacts the servers in the order that they
appear in the table. The range is from 1 to 3. The default value is 1.
10. In the Version field, specify the NTP version running on the server.
The range is 1 to 4. The default value is 4.
11. Click the Add button.
The SNTP server entry is added.
12. 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 Server Global Status
information.
Table 11. SNTP Server Status information
Field Description
Address All the existing server addresses. If no server configuration exists, a message stating
that no SNTP server exists displays on the page.
Last Update Time The local date and time (UTC) that the response from this server was used to update
the system clock.
Last Attempt Time The local date and time (UTC) that this SNTP server was last queried.
