1、安装linuxptp

<code>sudo apt-get install linuxptp
复制代码

2、下载linuxptp源码：

<code>git clone git://git.code.sf.net/p/linuxptp/code linuxptp
复制代码

<code>cd linuxptp
cp configs/gPTP.cfg ./
vim gPTP.cfg
复制代码

添加：

<code>p2p_dst_mac                01:1B:19:00:00:00
复制代码

修改：

<code>neighborPropDelayThresh        80000
ptp_dst_mac                01:1B:19:00:00:00
复制代码

3、参考README设置：

<code>sudo vim /usr/share/doc/linuxptp/README.Debian
复制代码

  1. Default configuration
  The default configuration can be found in /etc/linuxptp/ptp4l.conf.
This is the default.cfg provided by the upstream source.
  2. Systemd services
  The service ptp4l invokes ptp4l on eth0 by default. To adjust the
parameters, follow these steps:
  1. create a directory /etc/systemd/system/ptp4l.service.d
  2. place a file with its name ending in .conf there
  3. put these lines into the file, with the parameters adjusted to your needs:
  [Service]
ExecStart=
ExecStart=/usr/sbin/ptp4l -f /etc/linuxptp/ptp4l.conf -i eth0
  参考示例：

/home/amine/linuxptp/gPTP.cfg
#
# 802.1AS example configuration containing those attributes which
# differ from the defaults. See the file, default.cfg, for the
# complete list of available options.
#
[global]
gmCapable       1
priority1       248
priority2       248

logSyncInterval       -3
syncReceiptTimeout   3
neighborPropDelayThresh   80000

ptp_dst_mac       01:1B:19:00:00:00
p2p_dst_mac       01:1B:19:00:00:00
network_transport   L2
delay_mechanism       P2P

  /etc/systemd/system/ptp4l.service.d/gPTP.conf

<code>[Service]
ExecStart=
ExecStart=/usr/sbin/ptp4l -2 -f /home/amine/linuxptp/gPTP.cfg -i eth0.10 -i eth0.20 -i eth0.30 -i eth0.40 -i eth0.50 -i eth0.60 -i eth0.70 -i eth0.80 eth0.90 -i eth0.100 -i eth0.110 -i eth0.120 -i eth0.130 -i eth0.140 -i eth0.150 -i eth0.160 -i eth0.170 -i eth0.180 -q -l 6 -S
复制代码

特殊阐明：
我设置的VLAN网卡比力多，导致ptp4l.service启动错误，我修改了

<code>/lib/systemd/system/ptp4l.service
复制代码

的 [Unit] 增长

<code>After=network.target
复制代码

[Unit]Description=Precision Time Protocol (PTP) serviceDocumentation=man:ptp4l<code>After=network.target
复制代码
