现场设备两台S105设备进行堆叠,由于现场的业务还在逐步迁移的阶段,只有主设备上单接了Bras设备。业务网关在bras上。
目前业务高峰期会有卡顿的情况,单个堆叠口跨框流量较大达到98%,另一个堆叠口基本没有发包。
当前收集诊断发现接口流量不均的现象还是比较明显:

两个框的堆叠口都在一块单板上,不会出现本板堆叠口优先的情况。单播负载不均衡是hash不均导致的,建议修改负载分担模式
另外跨框流量太多,建议把聚合做成跨框的,比如聚合204,入方向流量很大,但1框上的1/7/0/1端口没有被选中,被SHUT DOWN了。

由于无法确定客户现场的具体流量类型,客户最好按照相应的参数来测试,看哪种负载分担模式效果最好。
