Configuring NTP Server Mode
Set a remote server whose ip address is ip-address as the local time server.
ip-address specifies a host address other than a 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.
Tab le 436 Configure NTP Time Server
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 at the opposite end.
Perform the following configurations in System View.
