Configuring NTP client/server mode with authentication
Network requirements
As shown in Figure 62 , perform the following configurations to synchronize the time between SecBlade
and Device and ensure network security. More specifically:
• The local clock of Device is to be configured as a reference source, with the stratum level of 2.
• SecBlade works in client mode and Device is to be used as the NTP server of SecBlade, with
SecBlade as the client.
• NTP authentication is to be enabled on both Device and SecBlade.
