HP MSR2000/3000/4000 Router Series Network Management and Monitoring Command Reference

112
• If the specified source interface is down, the device searches the routing table for the outbound
interface, and uses the primary IP address of the outbound interface as the source IP address for
NTP messages.
Examples
# Specify the source interface for NTP messages as Ethernet 1/1.
<Sysname> system-view
[Sysname] ntp-service source ethernet 1/1
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 { ip-address | peer-name } [ vpn-instance vpn-instance-name ]
[ authentication-keyid keyid | priority | source interface-type interface-number | version number ] *
undo ntp-service unicast-peer { ip-address | peer-name } [ vpn-instance vpn-instance-name ]
Default
No symmetric-passive peer is specified for the device.

Parameters
ip-address: Specifies an IP address of the symmetric-passive peer. It must be a unicast address, rather
than a broadcast address, a multicast address or the IP address of the local clock.
peer-name: Specifies a host name of the symmetric-passive peer, a case-insensitive string of 1 to 255
characters.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the symmetric-passive peer belongs,
where vpn-instance-name 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, where
keyid is in the range of 1 to 4294967295. If this option is not specified, 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.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and the
default is 4.
