Configure the MA5616 for clock synchronization in the NTP peer mode. In the peer mode, configure only the active peer, and the passive peer need not be configured. In the peer mode, the active peer and the passive peer can synchronize with each other. The peer with a higher clock stratum is synchronized by the peer with a lower clock stratum.
Run the ntp-service refclock-master command to configure the local clock as the master NTP clock, and specify the stratum of the master NTP clock.
Run the ntp-service unicast-peer command to configure the NTP peer mode, and specify the IP address of the remote server that functions as the local timer server and the interface for transmitting and receiving NTP packets.
NOTE:
In this command, ip-address is a unicast address, which cannot be a broadcast address, a multicast address, or the IP address of a reference clock.
After the source interface of the NTP packets is specified by source-interface, the source IP address of the NTP packets is configured as the primary IP address of the specified interface.
One MA5616 functions as the NTP active peer (IP address of the L3 interface of VLAN 2: 10.10.10.10/24) and works on clock stratum 4, the other MA5616 (IP address: 10.10.10.20/24) functions as the NTP passive peer, the active peer sends a clock synchronization request packet through the VLAN L3 interface to the passive peer, the passive peer responds to the request packet, and the peer with a higher clock stratum is synchronized by the peer with a lower clock stratum. To perform these configurations, do as follows:
huawei(config)#ntp-service refclock-master 4
huawei(config)#ntp-service unicast-peer
huawei(config)#vlan 2 standard
huawei(config)#port vlan 2 0/0 1
huawei(config)#interface vlanif 2
huawei(config-if-vlanif2)#ip address 10.10.10.10 24
huawei(config-if-vlanif2)#quit
