Ntp-Service Max-Dynamic-Sessions - HP MSR1003-8S Command Reference Manual

source interface-type interface-number: Specifies the source interface for IPv6 NTP messages. If the
specified IPv6 NTP server address is not a link local address, the source IPv6 address for IPv6 NTP
messages sent by the local device to the NTP server is the IPv6 address of the specified source interface.
If the specified IPv6 NTP server address is a link local address, the IPv6 NTP messages are sent from the
specified source interface, and the source address of the messages is the link local address of the
interface. The interface-type interface-number argument represents the interface type and number. If you
do not specify an interface, the device automatically selects the source IPv6 address of IPv6 NTP
messages. For more information, see RFC 3484.
Usage guidelines
When you specify an IPv6 NTP server for the device, the device is synchronized to the IPv6 NTP server,
but the IPv6 NTP server is not synchronized to the device.
To synchronize the PE to a PE or CE in a VPN, specify the vpn-instance vpn-instance-name option in the
command.
If you include the vpn-instance vpn-instance-name option in the undo ntp-service unicast-server
command, the command removes the NTP server with the IP address of ip-address in the specified VPN.
If you do not include the vpn-instance vpn-instance-name option in the command, the command removes
the NTP server with the IP address of ip-address in the public network.
If the specified IPv6 address of the NTP server is a link local address, you must specify the source
interface for NTP messages and cannot specify a VPN for the NTP server.
Examples
# Specify the IPv6 NTP server 2001::1 for the device.
<Sysname> system-view
[Sysname] ntp-service ipv6 unicast-server 2001::1
