交换机的CPU很高，但我show出来的进程所占用的CPU不到20%，而交换机下的业务也正常，请大神请点一下，谢谢！！
补充一点，CPU并不是一直都会很高，高了一段时间后它自己会自动地降下去

设备不是DHCP SERVER，只算是一台接入交换机

3：MAC address table status ?

1.Version 12.2(35)SE5
2.where is the bug manager? How can i search？
3.The mac address table is stable
4.STP is stable too, I could not find the Topology Change message in show logging
5.I didn't do anything and I don't know when it happens , I found this problem on zabbix ,but the zabbix deployed recently
6.show log without any alarm message
by the way , this problem doesn't happen all the time,It will automatically return to normal

看下设备开机使用时间是否过长，过长的话需要重启设备，释放资源
