Last Attempt Status Specifies 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.
• Other. None of the following enumeration values.
• Success. The SNTP operation was successful and the system time
was updated.
• Request Timed Out. A directed SNTP request timed out without
receiving a response from the SNTP server.
• 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 through the leap indicator field on the
SNTP message.

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.

packet.
