Last Unicast Attempt Time—The time of the most recent attempt by the 
switch to synchronize with an SNTP unicast server.

•

Client Mode—The configured SNTP client mode (Unicast or Broadcast). 
See the System Time to configure this mode.

•

Server Maximum Entries—Maximum number of servers that you can 
configure on the switch.

•

Server Current Entries—Number of SNTP servers currently configured on 
the system, as listed in the Unicast SNTP Servers Table.

•

Broadcast Count—Number of SNTP broadcast packets that the switch has 
received from SNTP servers.

Use the SNTP Authentication page to configure encryption keys, which contain 
the identifying information that the switch uses to authenticate to STNP servers. 
You also use this page to enable the SNTP authentication service.

When you define SNTP servers that the switch can use, you specify whether a 
server uses authentication and which authentication key it uses.

You must configure at least one trusted authentication key before you enable SNTP 
authentication. Otherwise, the 

Failed to enable SNTP Authentication 

message displays.

To configure an authentication key and enable this service:

Click Administration > Time Settings > SNTP Authentication in the navigation 
window.

The SNTP Authentication Table displays each currently configured authentication 
key and whether the key is currently enabled for use as a trusted key.

Select Enable to require the switch to authenticate to an SNTP server before 
synchronizing its time.

Click Apply. Your changes are saved to the Running Configuration.
