思科和华为交换机ping 丢包的问题？

思科ping华为有丢包，而华为的ping 思科没有丢包，这是为什么？信息如下：
华为的可以装思科的光模块吗？？
下面是思科Ping信息：

Answer 1

看双工和速率都协商成功了。没有问题，丢包可能是线路问题或两端参数不同导致

正常来说是不可以使用的，但是实际我用过，不建议用，容易出现问题。

Answer 2

最可能的原因是思科和华为交换机端口自协商的问题，把两边的端口速率和双工方式配置成固定一样的就可以了，如都设置为1000Mbps，全双工。
华为能否装思科的光模块，需要测试后才知道，不同规格的不一样。

Answer 3

华为和cisco对ping，cisco有丢包是正常的。华为接口上有预防DDOS的攻击设置，但关键还是看丢包是否为保护性丢包，如果不是，建议检查下端口模式或者变更下mtu值，或许就是模块上的差异了。

Answer 4

华为和思科的设置命令有所不同，你看看是不是设置的问题
