Description
Use the
ntp-service source-interface
command to specify an interface for sending NTP messages.
Use the
undo ntp-service source-interface
command to remove the configured interface for sending
NTP messages.
If you do not wish the IP address of a certain interface on the local device to become the destination
address of response messages, you can use this command to specify a particular interface for sending
all NTP messages, so that the source address in all NTP messages is the primary IP address of this
interface.
Examples
# Specify that all NTP messages are to be sent out from VLAN-interface 1.
[Sysname] ntp-service source-interface vlan-interface 1

Parameters
vpn-instance vpn-instance-name
: Specifies a VPN instance by its name, where
vpn-instance-name
is
a string of 1 to 31 characters.
ip-address
: IP address of the symmetric-passive peer. It must be a host address, rather than a
broadcast address, a multicast address or the IP address of the local clock.
peer-name
: Host name of the symmetric-passive peer, a string of 1 to 20 characters.
authentication-keyid keyid
: Specifies the key ID to be used for sending NTP messages to the peer,
where
keyid
is in the range of 1 to 4294967295.
priority
: Specifies the peer designated by
ip-address
or
peer-name
as the first choice under the same
condition.
source-interface interface-type interface-number
: Specifies an interface for sending NTP messages.
In an NTP message the local device sends to its peer, the source IP address is the primary IP address
of this interface.
interface-type interface-number
represents the interface type and number.
version number
: Specifies the NTP version, where
number
is in the range of 1 to 3 and defaults to 3.
Description
Use the
ntp-service
unicast-peer
command to designate a symmetric-passive peer for the device.
