SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The switch operates only as
an SNTP client and cannot provide time services to other systems.
Last Update Time The local date and time (UTC) that the SNTP client last updated the system
clock.
Last Attempt Time The local date and time (UTC) of the last SNTP request or receipt of an
unsolicited message.
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.
• Other.
The status of the last request is unknown.

• Server Unsynchronized. The SNTP server is not synchronized with its
peers. This is indicated by the leap indicator field in the SNTP message.
