如题，比如我现在在3750G堆叠上配置了两个接口组成一个3层LACP通道，3750默认是基于源MAC地址的负载均衡，如果我现在修改模式为基于源和目的IP，那会不会引起正在使用网络的服务器网络中断？

哪位帮忙看看呀，顶起来

Note: The port-channel load-balance src-dst-mixed-ip-port command can change the hardware forwarding on PFC/DFC/CFC of Supervisor and can cause interruption to traffic for several seconds to minutes until the new hash algorithm has been calculated and starts to forward the traffic accordingly. Any change in the hash algorithm is recommended during non-production hours.
建议还是自己做实验测试一下，通过 show etherchannel load-balance 和 test etherchannel load-balance interface port-channel X ... 的方式找到 某一条 数据流 走的link，然后modify load balance 方式
