336 CHAPTER 11: SYSTEM MANAGEMENT
broadcast, multicast, or reference clock IP address. In this case, the local switch
operates in client mode. In this mode, only the local client synchronizes its clock
with the clock of the remote server, while the reverse synchronization will not
happen.
Perform the following configurations in system view.
NTP version number number ranges from 1 to 3 and defaults to 3; the
authentication key ID keyid ranges from 0 to 4294967295; interface-name or
interface-type interface-number specifies the IP address of an interface, from
which the source IP address of the NTP packets sent from the local switch to the
time server will be taken; priority indicates the time server will be the first choice.
Configuring NTP Peer Mode Set a remote server whose IP address is
ip-address as the peer of the local equipment. In this case, the local equipment
operates in symmetric active mode. ip-address specifies a host address other than
a broadcast, multicast, or reference clock IP address. In this mode, both the local
switch and the remote server can synchronize their clocks with the clock of the
opposite end.
Perform the following configurations in system view.
NTP version number number ranges from 1 to 3 and defaults to 3; the
authentication key ID keyid ranges from 1 to 4294967295; interface-name or
interface-type interface-number specifies the IP address of an interface, from
which the source IP address of the NTP packets sent from the local switch to the
peer will be taken; priority indicates that the peer will be the first choice for time
server.
Configuring NTP Broadcast Server Mode Designate an interface on the local
switch to transmit NTP broadcast packets. In this case, the local equipment
operates in broadcast mode and serves as a broadcast server to broadcast
messages to its clients regularly.
