Configuring Ntp In Symmetric Active/Passive Mode; Configuring Ntp In Broadcast Mode - HPE FlexFabric 5700 Series Network Management And Monitoring Configuration Manual

Step

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:
Step
1. Enter system view.
2. Specify a symmetric-passive
peer for the device.

Configuring NTP in broadcast mode

A broadcast server must be synchronized by other devices or use its local clock as a reference
source before synchronizing a broadcast client. Otherwise, the broadcast client will not be
synchronized to the broadcast server.
Configure NTP in broadcast mode on both broadcast server and client.
Configuring a broadcast client
Step
1. Enter system view.
2. Enter interface view.
