Usage guidelines
Execute the undo ntp-service ipv6 inbound enable command on an interface in the following cases:
• You do not want the interface to synchronize the peer devices in the corresponding subnet.
• You do not want the device to be synchronized by the peer devices in the subnet corresponding to
the interface.
Examples
# Disable GigabitEthernet 2/0/1 from processing IPv6 NTP messages.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] undo ntp-service ipv6 inbound enable
ntp-service ipv6 multicast-client
Use ntp-service ipv6 multicast-client to configure the device to operate in IPv6 NTP multicast client mode
and use the current interface to receive IPv6 NTP multicast packets.
Use undo ntp-service ipv6 multicast-client to remove the configuration.
Syntax
ntp-service ipv6 multicast-client ipv6-multicast-address
undo ntp-service ipv6 multicast-client ipv6-multicast-address

Parameters
ipv6-multicast-address: Specifies an IPv6 multicast address. An IPv6 broadcast client and an IPv6
broadcast server must be configured with the same multicast address.
Usage guidelines
After you configure the command, the device listens to IPv6 NTP messages using the specified multicast
address as the destination address. It is synchronized based on the received IPv6 NTP messages.
If you have configured the device to operate in IPv6 multicast client mode on an interface by using the
command, do not add the interface to any aggregate group. To add the interface to an aggregate group,
remove the configuration of the command.
