红帽全球峰会8.13.7.2. 为链路状态监控配置 ARP Ping
组守护进程
teamd 将 ARP REQUEST 发送到链路远程末尾的地址，以确定链接是否已启动。使用的方法与 arping 实用程序相同，但它不使用该实用程序。
准备包含 JSON 格式的新配置的文件，如下例所示：
此配置使用 arp_ping 作为链路监视器。
{
"device": "team0",
"runner": {"name": "activebackup"},
"link_watch":{
"name": "arp_ping",
"interval": 100,
"missed_max": 30,
"source_host": "192.168.23.2",
"target_host": "192.168.23.1"
},
"ports": {
"em1": {
"prio": -10,
"sticky": true
},
"em2": {
"prio": 100
}
}
}missing_max 选项是允许最多允许回复数的限值（例如，ARP 回复）。它应当与 interval 选项一同选择，以确定链接报告为 down 前的总时间。
要加载组端口的新配置 em2在包含 JSON 配置的文件中，以
请注意，旧配置将被覆盖，省略的任何选项都将重置为默认值。有关更多团队守护进程控制工具命令示例，请参阅
