配置单服务器场景的1588 ACR时钟同步示例
通过示例演示在单服务器场景下，如何在客户端路由器和服务器路由器上配置1588 ACR功能，以恢复时钟。
配置思路
配置单服务器场景的1588 ACR时钟同步功能的思路如下：
配置DeviceA作为服务器
配置DeviceC作为客户端
调整客户端和服务器之间的三层单播协商参数
配置客户端与服务器端的单播协商功能
在客户端配置PTP时钟源作为时钟参考源
操作步骤
- 配置DeviceA作为服务器
<DeviceA> system-view[~DeviceA] interface loopback 0
[*DeviceA-Loopback0] ip address 1.1.1.1 32
[*DeviceC-Loopback0] commit
[~DeviceA-Loopback0] quit
[*DeviceA] ptp-adaptive enable
[*DeviceA] ptp-adaptive device-type server
[*DeviceA] ptp-adaptive local-ip 1.1.1.1
[~DeviceA] commit
- 配置DeviceC作为客户端
<DeviceC> system-view[~DeviceC] interface loopback 0
[*DeviceC-Loopback0] ip address 2.2.2.2 32
[*DeviceC-Loopback0] commit
[~DeviceC-Loopback0] quit
[*DeviceC] ptp-adaptive enable
[*DeviceC] ptp-adaptive device-type client
[*DeviceC] ptp-adaptive local-ip 2.2.2.2
[*DeviceC] ptp-adaptive remote-server1-ip 1.1.1.1
[~DeviceC] commit
- 调整客户端和服务器之间的三层单播协商参数
# 配置客户端
[*DeviceC] ptp-adaptive request sync-interval 4
[*DeviceC] ptp-adaptive request announce-interval 12
[*DeviceC] ptp-adaptive request delay-resp-interval 6
[*DeviceC] commit
- 配置客户端与服务器端的单播协商功能
# 配置服务器端
[*DeviceA] ptp-adaptive acr unicast-negotiate enable
[*DeviceA] commit
# 配置客户端
[*DeviceC] ptp-adaptive acr unicast-negotiate enable
[*DeviceC] commit
- 在客户端配置PTP时钟源作为时钟参考源
[*DeviceC] clock source ptp synchronization enable
[*DeviceC] clock source ptp priority 1
[*DeviceC] clock source ptp ssm prc
[*DeviceC] commit
- 检查配置效果
