Ntp-Service Unicast-Peer - HPE FlexNetwork 10500 Series Network Management And Monitoring Command Reference

ntp-service unicast-peer

Use ntp-service unicast-peer to specify a symmetric-passive peer for the device.
Use undo ntp-service unicast-peer to remove the symmetric-passive peer specified for the device.
Syntax
ntp-service unicast-peer { peer-name | ip-address } [ vpn-instance vpn-instance-name ]
[ authentication-keyid keyid | priority | source interface-type interface-number | version number ]
*
undo ntp-service unicast-peer { peer-name | ip-address } [ vpn-instance vpn-instance-name ]
Default
No symmetric-passive peer is specified.

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.
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
