Configuring NTP Authentication

Configuring NTP Authentication

Context

In networks demanding higher security, the authentication function can be enabled when using the NTP protocol. Password authentication of both clients and servers ensures that a client only synchronizes with an authenticated device, improving the network security.

NTP authentication follows these rules:

  • NTP authentication must be enabled first; otherwise, authentication cannot be implemented.

  • NTP authentication needs to be configured on both the client and the server. Otherwise, NTP authentication does not take effect.

  • When NTP authentication is enabled, a trusted key is configured on the client.

  • Keys configured on the server and the client must be identical.

  • Devices attempting to synchronize their clocks must declare their keys as reliable or NTP authentication will fail.

NOTE:

In NTP symmetric peer mode, the symmetric active peer functions as a client and the symmetric passive peer functions as a server.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ntp-service authentication enable

    The NTP authentication function is enabled.

  3. Run ntp-service authentication-keyid key-id authentication-mode { md5 | hmac-sha256 } [ cipher ] password

    The NTP authentication key is configured.

  4. Run ntp-service reliable authentication-keyid key-id

    The reliable key is specified.

Follow-up Procedure

After NTP authentication configuration is complete, apply the NTP authentication key in Configuring NTP Operating Modes by specifying the authentication-keyid parameter.
