After you specify an IPv6 symmetric-passive peer for a device, the device polls and synchronize its
time with the peer device at the minimum polling interval. If the time discrepancy between the two
remains in the acceptable range, the system gradually increases the polling interval until the
maximum polling interval is reached. If the time discrepancy exceeds the acceptable range
repeatedly, the polling interval decreases gradually.
The polling interval configuration takes effect when the next polling starts.
Examples
# Specify the device with the IPv6 address of 2001::1 as the symmetric-passive peer of the device,
and specify the source interface for IPv6 NTP messages as VLAN-interface 1.
<Sysname> system-view
[Sysname] ntp-service ipv6 unicast-peer 2001::1 source vlan-interface 1

Parameters
server-name
: Specifies an NTP server by its host name, a case-insensitive string of 1 to 253
characters.
ipv6-address
: Specifies an NTP server by its IPv6 address. It must be a unicast address, rather
than a multicast address.
vpn-instance vpn-instance-name
: Specifies the MPLS L3VPN instance to which the NTP
server belongs. The
vpn-instance-name
argument is a case-sensitive string of 1 to 31
characters. If the NTP server is on the public network, do not specify this option.
authentication-keyid keyid
: Specifies the key ID to be used for sending NTP messages to
the NTP server. The value range for the
keyid
argument is 1 to 4294967295. If you do not specify
this option, the local device and NTP server do not authenticate each other.
