Configuring NTP authentication in symmetric peers mode

Follow these instructions to configure NTP authentication in symmetric peers mode:
An active symmetric peer can synchronize to the passive symmetric peer only when you configure
all the required tasks on both the active symmetric peer and passive symmetric peer.
When the active peer has a greater stratum level than the passive peer:
On the active peer, if NTP authentication is not enabled or no key is specified to associate with
the passive peer, the active peer synchronizes to the passive peer as long as NTP authentication
is disabled on the passive peer.
On the active peer, if NTP authentication is enabled and a key is associated with the passive
peer, but the key is not a trusted key, no matter whether NTP authentication is enabled or not on
the passive peer, the active peer does not synchronize to the passive peer.
When the active peer has a smaller stratum level than the passive peer:
On the active peer, if NTP authentication is not enabled, no key is specified to associate with the
passive peer, or the key is not a trusted key, the active peer can synchronize to the passive peer
as long as NTP authentication is disabled on the passive peer.

a trusted key after associating the
key with the NTP server.
