思科防火墙ASA5506X总是自动重启查看crash日志

 

 

 

查看启动时间有没有变化

show ver

结果

Cisco Adaptive Security Appliance Software Version 9.5(2) 
Device Manager Version 7.5(2)

Compiled on Sat 28-Nov-15 00:16 PST by builders
System image file is "disk0:/asa952-lfbff-k8.SPA"
Config file at boot was "startup-config"

ASA5506X up 34 mins 26 secs

注意ASA5506X up 34 mins 26 secs这一句，如果时间比较近，没有断电和reload命令重启的情况下应该是自动重启了

查看崩溃日志

show crash

结果

: Saved_Crash

注意Crashinfo collected on 08:39:26.869 Beijing Fri Jun 19 2020 这个是ASA防火墙崩溃记录的时间，如果能和故障对上，那么肯定是防火墙崩溃导致的重启

这个崩溃日志可以TFTP导出，服务端推荐3CDaemon，导出命令如下

dir #查看目录有没有崩溃日志文件
copy crash.txt tftp 
Source filename [crash.txt]? #确认源文件名
Address or name of remote host []? #输入tftp服务器地址回车
Destination filename [crash.txt]? #回车或输入自定义名称回车

针对在保设备，网上的解决方案是找TAC开case

目前怀疑温度过高或者硬件问题。
