请教下WS-C3750X-48交换机CPU进程问题

最近在查看接入交换机的CPU占用率,
使用show processes cpu history查看,平均占用率在30%左右。
使用show processes cpu sorted,查看具体进程占用情况中,有一下几个占用率较高的,请问这些是什么进程啊?

如果您使用SSH作为Telnet(VTY)线路的传输协议,则RSA密钥将每小时生成一次,您可以每小时处理一次“crypto sw pk pro”进程的CPU峰值。
其他你谷歌 或者思科官网查询都有的,自己熟悉查询。
然后一般情况低于7 80%的使用都是正常的,无需在意

这个进程“crypto sw pk pro”周期性每个小时冲高一次,是正常的。RFC就是这么规定的。。。
不用担心,没有业务影响。
参见RFC:
RFC 4253 ( http://www.ietf.org/rfc/rfc4253.txt, Page 22, Section 9).
如果你不想看到它每小时高一次,也有方法:
- removing RSA keys ("crypto key zeroize rsa").
or
- pointing SSH server to non-existing RSA keypair ("ip ssh rsa keypair-name FAKE"). This method will allow to disable SSH server but keep RSA keys for other purposes (IPsec, SSL, etc).
信息来自于咱们论坛的这个帖子:crypto sw pk pro进程每隔一小时引起交换机CPU利用率升高,如何解决

If you are using SSH as a transport protocol for Telnet (VTY) lines, the RSA key will be generated every hour and you can experience hourly cpu spikes for the process 'crypto sw pk pro'.

Virtual Exec:
The Exec process in Cisco IOS® software is responsible for communication on the tty lines (console, auxiliary, asynchronous) of the router. The Virtual Exec process is responsible for the vty lines (telnet sessions).
The Exec and Virtual Exec processes are Medium-priority processes, so if there are other processes that have a higher priority (High or Critical), the higher priority processes get the CPU resources.
Check heaps:
Checks the memory every minute. It forces a reload if it finds processor corruption.
Hulc LED Process:
Hulc LED Process is a process responsible for link status detection.
If there is SFP port in use, it might be a little bit high.
