9. Use the
NTP Version
drop-down menu to select the version of SNTP to use with this configuration
Currently version three and version four implementations of NTP are available. The latest version is
NTPv4, but the official Internet standard is NTPv3.
10.If necessary, select the
No Authentication
checkbox to allow communications with the NTP resource
without any form of security. This option should only be used with known NTP resources.
11.Select the
AutoKey Authentication
checkbox to use an Auto key protocol based on the public 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.
12.Select the
Symmetric Key Authentication
checkbox to use a single (symmetric) key for 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.
13.Enter an
Key ID
between 1-65534. The Key ID is a Key abbreviation allowing the switch to reference
multiple passwords.
14.Select the
Preferred Source
checkbox if this NTP resource is a preferred NTP resource. Preferred
sources are contacted before non-preferred resources. There can be more than one preferred source.
15.Refer to the
Status
field. The Status is the current state of the requests made from the applet. 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.
16.Click
OK
to save and add the changes to the running configuration and close the dialog.
17.Click
Cancel
to close the dialog without committing updates to the running configuration.
5.3.5 Viewing SNTP 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
