复制代码

mwan3track 通过ping检测判断了网络接口离线了，
之后接口就一直卡在了离线的状态。


配置mwan3参数时有一项是“当 Ping 成功次数达到这个数值后，已经被认为离线的接口将会重新上线”



这一项设置不应该能让接口重新上线吗？？？？？     还说我对这一项设置理解错了。




还是说网络接口的离线不是mwan3执行 ifdown 导致的。而是其他的服务导致了 接口的ifdown ？

还请大神们出来指导指导一下。    这个问题已经努力很久了，但还是没啥结果。

wwan0接口根本就不通啊！

wwan0接口根本就不通啊！

wwan0已经被ifdown了；如果在调试终端 ifup 接口；是可以重新再ping上的。

我就纳闷了难度每次接口下线，都要手动重新上线的吗？

接口在线改成1，ping的IP设成两个能ping通的外网就行了，如114.114.114.114，114.114.115.115

我的配置，掉线后完全可以自动上线。
config interface 'wan1'
        option enabled '1'
        option initial_state 'online'
        option family 'ipv4'
        list track_ip '114.114.114.114'
        list track_ip '114.114.115.115'
        option track_method 'ping'
        option reliability '1'
        option count '1'
        option size '56'
        option check_quality '0'
        option timeout '2'
        option interval '5'
        option failure_interval '5'
        option recovery_interval '5'
        option down '3'
        option up '3'
        option flush_conntrack 'never'

我的配置也和你的差不多，但我的是wann0用的dhcp
你那个好像是ppoe吧

我的K2P也有这个问题

我现在也是这样的问题，时间久点就有网口关了，但换别人的启动配置又正常，是不是源码要修改什么？

说明
在wwan0上配置的负载均衡策略4g_1, 在该接口去ping 114.114.114.114 之类的地址没用通
然后按照 /etc/config/mwan3 配置中的测量,将wwan0接口下线
楼主的需要检查 /etc/config/mwan3 里自己配置的策略时候可信


/etc/config/mwan3 的关键说明(以我配置的wan接口为例,楼主的配置肯定不是这个)
config interface 'wan'
        option enabled '1' #开启负载均衡策略
        list track_ip '119.29.29.29'
        list track_ip '114.114.114.114'
        list track_ip 'www.baidu.com'
        list track_ip 'www.qq.com'

        option family 'ipv4' #使用ipv4协议
        option reliability '2' #至少 track_ip 里面有2个地址ping通了,才会认为wan上线了(即执行Execute ifdown event on),否则执行(Execute ifdown event down, 此处楼主策略设置不正确,down了)





运行log,此处系统开机初始化顺序的问题,有ping失败的地方,如果不是反复出现,不用管
