Usage guidelines If you specify the source interface for IPv6 NTP messages, the device sets the source IP address of the IPv6 NTP messages as the primary IP address of the specified interface when sending the IPv6 NTP messages. When the device responds to an IPv6 NTP request, the source IPv6 address of the NTP response is always the IPv6 address of the interface that has received the IPv6 NTP request. If you do not want the IPv6 address of a certain interface on the local device to become the destination address for response messages, use this command. • If you have specified the source interface for IPv6 NTP messages in the ntp-service ipv6 unicast-server or ntp-service ipv5 unicast-peer command, the interface specified in the ntp-service ipv6 unicast-server or ntp-service ipv6 unicast-peer command serves as the source interface for IPv6 NTP messages. If you have configured the ntp-service ipv6 broadcast-server or ntp-service ipv6 multicast-server command, the source interface for the broadcast or multicast NTP messages is the interface configured with the respective command. • If the specified source interface is down, the device automatically selects the source IPv6 address. For more information, see RFC 3484.

Views System view Predefined user roles network-admin Parameters ipv6-address: Specifies an IPv6 address of the symmetric-passive peer. It must be a unicast address, rather than a multicast address. peer-name: Specifies a host name of the symmetric-passive peer, a case-insensitive string of 1 to 253 characters. 36

Usage guidelines
If you specify the source interface for IPv6 NTP messages, the device sets the source IP address of the IPv6
NTP messages as the primary IP address of the specified interface when sending the IPv6 NTP messages.
When the device responds to an IPv6 NTP request, the source IPv6 address of the NTP response is
always the IPv6 address of the interface that has received the IPv6 NTP request. If you do not want the
IPv6 address of a certain interface on the local device to become the destination address for response
messages, use this command.
If you have specified the source interface for IPv6 NTP messages in the
ntp-service ipv6
unicast-server
or
ntp-service ipv5 unicast-peer
command, the interface specified in the
ntp-service
ipv6 unicast-server
or
ntp-service ipv6 unicast-peer
command serves as the source interface for
IPv6 NTP messages. If you have configured the
ntp-service ipv6 broadcast-server
or
ntp-service
ipv6
multicast-server
command, the source interface for the broadcast or multicast NTP messages
is the interface configured with the respective command.
If the specified source interface is down, the device automatically selects the source IPv6 address.
For more information, see RFC 3484.
Examples
# Specify the source interface of IPv6 NTP messages as VLAN-interface 1.
<Sysname> system-view
[Sysname] ntp-service ipv6 source vlan-interface 1
ntp-service ipv6 unicast-peer
Use
ntp-service
ipv6
unicast-peer
to specify an IPv6 symmetric-passive peer for the device.
Use
undo ntp-service
ipv6
unicast-peer
to remove the IPv6 symmetric-passive peer specified for the
device.

Parameters
ipv6-address
: Specifies an IPv6 address of the symmetric-passive peer. It must be a unicast address,
rather than a multicast address.
peer-name
: Specifies a host name of the symmetric-passive peer, a case-insensitive string of 1 to 253
characters.
