Configuring NTP authentication for an active peer
Step Command Remarks
76. Enter system view. system-view N/A
By default, NTP authentication is
disabled.
77. Enable NTP authentication. ntp-service authentication enable
By default, no NTP authentication
key is configured.
ntp-service authentication-keyid
keyid authentication-mode md5
[ cipher | simple ] value
78. Configure an NTP
authentication key.
Configure the same authentication
key on the active symmetric peer
and passive symmetric peer.
79. Configure the key as a trusted
key. ntp-service reliable
authentication-keyid keyid By default, no authentication key is
configured to be trusted.
You can associate a non-existing
key with a passive peer. To enable
NTP authentication, you must
configure the key and specify it as
a trusted key after associating the
key with the passive peer.
ntp-service unicast-peer
{ ip-address | peer-name }
authentication-keyid keyid
80. Associate the specified key
with the passive peer.

Configuring NTP authentication in broadcast mode
Follow these instructions to configure NTP authentication in broadcast mode:
• A broadcast client can synchronize to the broadcast server only when you configure all the required
tasks on both the broadcast client and server.
• If NTP authentication is not enabled on the client, the broadcast client can synchronize to the
broadcast server no matter whether NTP authentication is enabled or not on the server.
