控制器意外重启检查步骤

1、使用命令检查重新启动的原因

#show switchinfo
Hostname is arubalab-MD
System Time:Wed May  6 17:41:25 EDT 2020
No crash information available.     ------> 检查是否有任何崩溃信息                                     
No kernel crash information available.
Reboot Cause: User reboot (Intent:cause:register 78:86:50:60)

show syslocation 

Location not configured

show version

Supervisor Card
Processor (XLP208 Rev B1 (Secure Boot) , 800 MHz) with 3797M bytes of memory.
32K bytes of non-volatile configuration memory.
1936M bytes of Supervisor Card system flash.

2、如果有崩溃信息,提取崩溃信息

#tar crash
#copy flash: crash.tar tftp: <ip address of tftp server> crash.tar

3、检查控制器是否有进程卡住

#show process monitor statistics 

4、检查CPU内存

#show cpuload
#show memory

5、收集log日志

#tar logs tech-support
#copy flash: logs.tar tftp: <ip address of tftp server> logs.tar

6、Call TAC进一步分析

附:日志压缩方式改变

从8.3.0.13、8.5.0.7、8.6.0.3 版本以后,tech-support 文件后缀已经改为.7z,之前版本控制器的log/tech-support都是通过’gzip’进行压缩。现在通过7za工具可以提高压缩效率,体积也更小。
