Ntp-Service Ipv6 Unicast-Peer - HPE FlexFabric 5930 Series Network Management And Monitoring Command Reference

Syntax
ntp-service ipv6 source interface-type interface-number
undo ntp-service ipv6 source
Default
No source interface is specified for IPv6 NTP messages. The device automatically selects the
source IP address for IPv6 NTP messages. For more information, see RFC 3484.

Parameters
interface-type interface-number: Specifies an interface by its type and number.
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 the 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 works 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 does not send IPv6 NTP messages.
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.
Syntax
ntp-service ipv6 unicast-peer { peer-name | ipv6-address } [ vpn-instance vpn-instance-name ]
[ authentication-keyid keyid | priority | source interface-type interface-number ] *
undo ntp-service ipv6 unicast-peer { peer-name | ipv6-address } [ vpn-instance
vpn-instance-name ]
Default
No IPv6 symmetric-passive peer is specified for the device.
