Configuring Ntp In Client/Server Mode; Configuring Ntp In Symmetric Active/Passive Mode - HP 6125XLG Configuration Manual

Configuring NTP in client/server mode

When the device operates in client/server mode, specify the IP address for the server on the client.
Follow these guidelines when you configure an NTP client:
A server must be synchronized by other devices or use its local clock as a reference source before
•
synchronizing an NTP client. Otherwise, the client will not be synchronized to the NTP server.
• If the stratum level of a server is higher than or equal to a client, the client will not synchronize to that
server.
You can configure multiple servers by repeating the ntp-service unicast-server and ntp-service ipv6
•
unicast-server commands.
To configure an NTP client:
Step
1. Enter system view.
2. Specify an NTP server for the
device.

Configuring NTP in symmetric active/passive mode

When the device operates in symmetric active/passive mode, specify on a symmetric-active peer the IP
address for a symmetric-passive peer.
Follow these guidelines when you configure a symmetric-active peer:
Execute the ntp-service enable command on a symmetric passive peer to enable NTP. Otherwise,
•
the symmetric-passive peer will not process NTP messages from a symmetric-active peer.
Either the symmetric-active peer, or the symmetric-passive peer, or both of them must be in
•
synchronized state. Otherwise, their time cannot be synchronized.
You can configure multiple symmetric-passive peers by repeating the ntp-service unicast-peer or
•
ntp-service ipv6 unicast-peer command.
To configure a symmetric-active peer:
Command
system-view
•
Specify an NTP server for the
device:
ntp-service unicast-server
{ ip-address | server-name }
[ vpn-instance
vpn-instance-name ]
[ authentication-keyid keyid |
priority | source interface-type
interface-number | version
number ] *
•
Specify an IPv6 NTP server for
the device:
ntp-service ipv6 unicast-server
{ ipv6-address | server-name }
[ vpn-instance
vpn-instance-name ]
[ authentication-keyid keyid |
priority | source interface-type
interface-number ] *

Remarks
N/A
By default, no NTP server is
specified for the device.
