Configuring the ProCurve Wireless Edge Services xl Module
Enabling Secure Network Time Protocol (NTP)
5. In the NTP Version field, use the drop-down menu to select the version of
NTP to use with this configuration.
Although the latest version of the NTP implementation is NTPv4, the
official Internet standard is NTPv3.
6. Select the authentication method:
• No Authentication—No authentication is used.
• AutoKey Authentication—The Wireless Edge Services xl Module and
the neighbor automatically generate the keys that authenticate their
communications, using digital certificates to secure the automatic
process.
This option is not available when Broadcast Server is selected as the
neighbor type in step 3.
• Symmetric Key Authentication—The module and the neighbor authen-
ticate communications with the same shared key.
7. If you selected Symmetric Key Authentication in step 6, in the Key ID field
enter the symmetric key ID.
The key ID references the symmetric key that you created earlier for this
neighbor. (See “Adding Symmetric Keys” on page 2-150.) The key value
for the symmetric key must be the same for both the sender and the
receiver.
8. Check the Preferred Source box if the neighbor is a preferred NTP
resource.
Preferred sources are contacted before non-preferred resources. You can
specify more than one preferred source.
This option is not available when Broadcast Server is selected as the
neighbor type (see step 3).
9. Click the OK button. The neighbor is now listed on the Special Features >
Secure NTP > NTP Neighbor screen.
