Configuring NTP authentication in symmetric active/passive
mode
When you configure NTP authentication in symmetric peers mode, enable NTP authentication, configure
an authentication key, set the key as a trusted key on both active peer and passive peer, and associate
the key with the passive peer on the active peer. The key IDs and key values configured on the active peer
and passive peer must be the same. Otherwise, NTP authentication fails.
To configure NTP authentication for an active peer:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable NTP authentication. ntp-service authentication enable
By default, NTP authentication is
disabled.
