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.
9.  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.
10. 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.
11. In the Version field, specify the NTP version running on the server. 
The range is 1 to 4. The default value is 4. 
12. Click the Add button. 
The SNTP server entry is added.
13. 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.
