cisco 6509核心交换机cpu使用率高

请教各位大神 我公司的核心交换机6509出现cpu使用率高达99%，出现这个问题是公司DBA在两台数据库服务器上拷贝数据使用的scp，只要使用scp协议拷贝数据核心交换机cpu使用率就99%，而使用sftp协议就不会出现这个问题，cpu使用率高的时候查看过进程主要是交换机的INPUT进程cpu使用率高，交换机ios为s72033-advipservicesk9_wan-mz.122-33.SXI14.bin，debug过看日志都是这两台数据库之间的ack包，而且发包非常多，有大神知道为什么用scp协议就会出现这个问题吗？
CPU utilization for five seconds: 99%/61%; one minute: 99%; five minutes: 99%

可以看一看配置吗？
