Command Parameters

auth-enable: Activates MD5 or SHA1 authentication on this Network Time Protocol (NTP) server. Without this option, the NTP server will not have any authentication by default.
authentication-key <0-65534>: Specifies the key ID value used to generate the MD5 or SHA1 digest for the Network Time Protocol (NTP) server. The default authentication key is 0, which indicates disabled authentication.
enable: Activates the Network Time Protocol (NTP) server.
source-ip WORD <0-46>: Specifies the source IP for the server. If you do not configure source-ip, by default, the source-ip entry is initialized to 0.0.0.0. The IP address specified can be any local interface. This parameter applies only to NTPv3.
WORD<0-255>: Specifies the IPv4 or IPv6 address of the NTP server.

Default

The default configuration does not use MD5 authentication.
