3、交换引擎cpu利用率
vss-6513#remote login switch
vss-6513-sp#show processes cpu | e 0.00
CPU utilization for five seconds: 72%/43%; one minute: 33%; five minutes: 29%
PID 5Sec 1Min 5Min Process
1 10.3% 1.9% 1.6% kernel
3 0.0% 0.0% 0.0% devc-pty

4、运行IOS版本
vss-6513#show version | in boot
System image file is "sup-bootdisk:s72033-adventerprisek9-vz.122-33.SXI3.bin"
5、故障诊断
This should be a SW bug.
A somewhat similar bug is the following:
CSCsy61956 Bug Details
Crash in ios-base when running 'show ip route' or 'show bgp' commands
Symptom:
A Cat6K running modular IOS version 12.2(33)SXI may crash when running 'sh ip route vrf ..' or 'show bgp ..' commands.
Conditions:
Must be running modular IOS. Not seen in non-modular
Workaround:
None

6、解决办法
升级s72033-adventerprisek9_wan-mz.122-33.SXI4a.bin版本后，CPU利用率恢复正常。
