(Optional) Configuring the Peer Mode

(Optional) Configuring the Peer Mode

In peer mode, the two peers synchronize clocks with each other. One end can send the clock synchronization request message to the other and respond to the clock synchronization request message from the peer.

Procedure

  • Configure the NTP symmetric active end.
    1. Run system-view

      The system view is displayed.

    2. (Optional) Run ntp-service [ ipv6 ] source-interface interface-type interface-number [ vpn-instance vpn-instance-name ]

      The source interface for sending NTP packets is specified.

    3. Run:

      • To specify an IP address for the remote peer, run the ntp-service unicast-peer ip-address [ version number | authentication-keyid key-id | source-interface interface-type interface-number | vpn-instance vpn-instance-name | preference | maxpoll max-number | minpoll min-number | preempt | port port-number ] * command.
      • To specify an IPv6 address for the remote peer, run the ntp-service unicast-peer ipv6 ipv6-address [ authentication-keyid key-id | source-interface interface-type interface-number | vpn-instance vpn-instance-name | preference | maxpoll max-number | minpoll min-number | preempt | port port-number ] * command.

      If step 2 is performed, and source-interface is specified in both Step 2 and Step 3, use the source interface specified in Step 3 preferentially.

      ip-address is the NTP peer IP address. It can be a host address, but not a broadcast address, a multicast address, or the IP address of the reference clock.

      NOTE:

      After the NTP peer is specified, the local Router runs in symmetric active mode. The symmetric passive end does not need to be configured.

    4. Run commit

      The configuration is committed.

  • (Optional) Configure the NTP symmetric passive end.
    1. Run system-view

      The system view is displayed.

    2. Run ntp-service [ ipv6 ] source-interface interface-type interface-number [ vpn-instance vpn-instance-name ]

      The source interface for sending NTP packets is specified.

      Commonly, specify the IP address of the NTP symmetric passive on the symmetric active. The symmetric active and symmetric passive can then exchange NTP packets using this IP address.

      If the source interface to send NTP packets is specified on the symmetric passive end, the IP address of the NTP peer configured on the symmetric active end must be the same. Otherwise, the active end cannot process NTP packets sent from the passive end and clock synchronization fails.

    3. Run commit

      The configuration is committed.
