Configuring the NTP Peer
To configure the software clock to synchronize
a peer or to be synchronized by a peer, use the peer command. A
maximum of eight NTP peers can be configured. To disable this capability, use
the
no form of the command.
device(config-ntp)# peer 1.2.3.4 key 1234
device(config-ntp)# peer 1:2::3:4 key 1234
The peer command is not
effective if the NTP is enabled in client mode only.
Note: When the NTP server or peer is configured,
the
master
command is not configured; upon configuring the clock set command, the
system clock is not synchronized. When the master command is
configured, and upon configuring the clock set command, the
system clock is synchronized and the reference time will be the local clock. To have active peers at both the ends, you must
disable NTP, configure the peers, and enable NTP using the no disable command.
