Configuring The Ntp Symmetric Peers Mode - HP 5820X Switch Configuration Manual

To configure an NTP client:
To do...
1. Enter system view.
2. Specify an NTP server for the
device.
NOTE:
In the ntp-service unicast-server command,
•
broadcast address, a multicast address or the IP address of the local clock.
• When the source interface for NTP messages is specified by the source-interface argument, the
source IP address of the NTP messages is configured as the primary IP address of the specified
interface.
A device can only act as a server to synchronize the clock of other devices after its clock has been
•
synchronized. If the clock of a server has a stratum level higher than or equal to that of a client's
clock, the client will not synchronize its clock to the server's.
• You can configure multiple servers by repeating the ntp-service unicast-server command. The clients
will select the optimal reference source.

Configuring the NTP symmetric peers mode

For devices working in the symmetric mode, specify a symmetric-passive peer on a symmetric-active peer.
To configure a symmetric-active device:
To do...
1. Enter system view.
2. Specify a symmetric-passive
peer for the device.
Use the command...
system-view
ntp-service unicast-server [ vpn-
instance vpn-instance-name ] { ip-
address | server-name }
[ authentication-keyid keyid |
priority | source-interface
interface-type interface-number |
version number ] *
ip-address
must be a unicast address, rather than a
Use the command...
system-view
ntp-service unicast-peer [ vpn-
instance vpn-instance-name ] { ip-
address | peer-name }
[ authentication-keyid keyid |
priority | source-interface
interface-type interface-number |
