Configuring the ProCurve Wireless Edge Services zl Module
Enabling Secure Network Time Protocol (NTP)
Configuring Authentication for Secure NTP
When the Wireless Edge Services zl Module requires authentication for secure NTP,
it drops all NTP packets unless they are encrypted with the correct key. Authentication
ensures that the server providing system time to the Wireless Edge Services zl Module
is trusted.
You have two options for configuring authentication:
■ Using auto key—NTP devices authenticate with digital certificates, which they
use to generate encryption keys automatically.
■ Using symmetric keys—You manually specify the keys that NTP devices use
to encrypt communications.
Configuring Auto Key for Secure NTP. To configure auto key, follow these steps:
1. Select Special Features > Secure NTP. Configure initial settings as described in
“Configuring Secure NTP Options” on page 2-143.
2. Select the Configuration tab.
