高端分布式防火墙M9000关于blade接口流量统计的说明

某局点监控了Blade-Aggregation1的接口流量状态，有些时候该接口流量有突增。

经过对比发现，Blade-Aggregation的流量远大于实际整机的流量。

Blade-Aggregation统计的业务口流量，通常对应上送CPU的流量，走逻辑的流量不统计在内。

接口统计的流量和业务流量有些差距，他还包括一些板间通信，会话热备这类的系统内部报文。

突增的时间点可以看下是否有策略变动，或者不走cpu的流量上墙。 

Blade-Aggregation接口的流量不具备什么监控价值，cpu还是建议监控利用率和内存。流量大小以接口为准即可~。
