Configure System Information User Manual72
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 valid range is 1 to 3. The default is 1.
11. In
the Version field, specify the NTP version running on the server.
The range is 1 to 4.
The default 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 fields in the SNTP Server Status
table.
Table 8. 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.
Last Attempt Status The status of the last SNTP request or unsolicited message for both unicast and
broadcast modes. If no message was received from a server
, a status of Other is
displayed.
These values are appropriate for all operational modes:
Requests The number of SNTP requests made to this server since last agent reboot.
Failed Requests The number of failed SNTP requests made to this server since the last reboot.
• Other. The status of the last request is unknown, or no SNTP responses were
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.
