Parameters
peer-name
: Specifies a symmetric-passive peer by its host name, a case-insensitive string of 1 to
253 characters.
ip-address
: Specifies a symmetric-passive peer by its IP address. It must be a unicast address,
rather than a broadcast address, a multicast address, or the IP address of the local clock.
vpn-instance vpn-instance-name
: Specifies the MPLS L3VPN instance to which the
symmetric-passive peer belongs. The vpn-instance-name argument is a case-sensitive string
of 1 to 31 characters. If the symmetric-passive peer 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 peer. The value range for the
keyid
argument is 1 to 4294967295. If you do not specify this
option, the local device and the peer do not authenticate each other.
maxpoll maxpoll-interval : Specifies the maximum polling interval. The value range for the
maxpoll-interval argument is 4 to 17, to which base 2 is raised to get the interval in seconds.
The maximum polling interval is in the range of 2
4
to 2
17
(16 to 131072) seconds. The default value
for the maxpoll-interval argument is 6 and the default maximum polling interval is 2
6
(64)
seconds.
minpoll minpoll-interval : Specifies the minimum polling interval. The value range for the
minpoll-interval
argument is 4 to 17, to which base 2 is raised to get the interval in seconds.
The minimum polling interval is in the range of 2
4
to 2
17
(16 to 131072) seconds. The default value for
the minpoll-interval argument is 6 and the default minimum polling interval is 2
6
(64) seconds.
priority
: Specifies the peer specified by
ip-address
or
peer-name
as the first choice under
the same condition.
source interface-type interface-number
: Specifies the source interface for NTP
messages. In an NTP message the local device sends to its peer, the source IP address is the
primary IP address of this interface. The
interface-type interface-number
argument
represents the interface type and number. If you do not specify this option, the device searches the
routing table for the outgoing interface and uses the primary IP address of the outgoing interface as
the source IP address of the NTP messages.
version number : Specifies the NTP version. The value range for the number argument is 1 to 4.
The default value is 4.
Usage guidelines
When you specify a passive peer for the device, the device and its passive peer can be synchronized
to each other. If their clocks are in synchronized state, the clock with a high stratum level is
synchronized to the clock with a lower stratum level.
To synchronize the PE to a PE or CE in a VPN instance, provide vpn-instance
vpn-instance-name in your command.
If you include
vpn-instance vpn-instance-name
in the
undo ntp-service
unicast-peer
command, the command removes the symmetric-passive peer in the specified
VPN instance. If you do not include
vpn-instance vpn-instance-name
in the command, the
command removes the symmetric-passive peer on the public network.
