Viewing NTP Associations

The interaction between the switch and a SNTP server constitutes an association. SNTP
associations can be either a peer association (the switch synchronizes to the another system or
allows another system to synchronize to it), or a server association (only the switch synchronizes to
the SNTP resource, not the other way around).
To review the switch's current SNTP associations:
1. Select Services > Secure NTP from the main menu tree.

resource without any form of security. This option should only be used with known NTP
resources.
key infrastructure (PKI) algorithm. The SNTP server uses a fast algorithm and a private value to
regenerate key information on the arrival of a message. The switch sends its designated public
key to the server for credential verification and the two exchange messages. This option is
disabled when the Broadcast Server checkbox is selected.
encryption and decryption. Since both the sender and the receiver must know the same key, it
is also referred to as shared key cryptography. The key can only be known by the sender and
receiver to maintain secure transmissions.
reference multiple passwords.
Preferred sources are contacted before non-preferred resources. There can be more than one
preferred source.
Requests are any "SET/GET" operation from the applet. The Status field displays error
messages if something goes wrong in the transaction between the applet and the switch.
