Authentication-check

The authentication-check command provides for the option to skip the rejection of NTP PDUs that do not match the authentication key or authentication type requirements. The default behavior when authentication is configured is to reject all NTP protocol PDUs that have a mismatch in either the authentication key ID, type, or key.

When authentication-check is configured, NTP PDUs are authenticated on receipt. However, mismatches cause a counter to be increased, one counter for key ID, one for type, and one for key value mismatches.

CLI Syntax:

config>system>time>ntp
    authentication-check

Example:

config>system>time>ntp# authentication-check
config>system>time>ntp# no shutdown
