[问题求助]网卡绑定后不定期link down [复制链接]

有.一台ES3的server，现在2块网卡做了bonding，但是发现其中的et.h1每天都会有link 重复up. down的情况发生，想问问大家有遇到过这样的情况吗？--- 印刷

不知是否是因为2块卡的速度不同造成这个问题，平时真正在使用的是千兆的eth1：
# cat /proc/net/bond0/info
Bonding Mode: fault-tolerance (active-backup)
Currently Active Slave: eth1
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Multicast Mode: all slaves

Slave Interface: eth1
MII Status: up
Link Failure Count: 1198

Slave Interface: eth0
MII Status: up
Link Failure Count: 68

看到下面这个帖子，会不会是因为交换机和网卡协商时发生的问题呢？

1、可能BCM5701有兼容性问题。建议换成和ETH0一样的INTEL82559
2、做bond的两块网卡的工作模式，速率必须完全一致，这样你2块加起来也不过200M，还不及你一个千兆的多，建议交换机加千兆模块。
3、交换机和网卡端都强制指定速率试试。

恩 好

我先试一下在server上配置，因为网络设备不归我管，要改很麻烦的～～
