你好，

通过基本的信息可以判断这里应该是手动重启有关系。重启时间是 Fri Feb 21 2025，也就是今天05:08:57 。

你的show ver信息应该还没输出完成。完整的信息里面应该还有“Last reset from xxx” 这个描述信息，可以进一步参考这个信息判断。

如果有AAA的话，可以看看那会儿是哪个账号登录进了设备。

当然如果是设备Crash导致的重启的话，可以看看设备是否有crashinfo，一般会存在bootflash里面。dir bootflash:应该可以看到。

或者：

show platform crashdump 也可以看看有无Crash的记录。

Based on the current information.
First, the most recent reboot was at 05:08:57 UTC+8 Fri Feb 21 2025, which was rebooted by reload.
Second, earlier, at 02/20/2025 20:24:42, the device crashed.
So, you can still check whether there is crashinfo in the bootflash of your Cat4500 device. If so, you can check the content in crashinfo. Most importantly! When did your device reboot? The time needs to match. The two reboots we have seen so far are a crash on February 20 and a reload command reboot on February 21. Which one is the device failure time?

Thank you for your reply，How can i search bootflash in the show tech-support .txt or i can use which commadn to check it.   I'm sorry because I don't have much experience with this.

sorry, Last reset from Reload in the show version output

Well ，In this case, the device was rebooted by a reload operation, which seems to be the expected operation. As mentioned before, if there is AAA audit or log server, you can see who logged in at the corresponding time.

Can we see the output to the command "dir ?"?  

There should be a crashlog/crashinfo directory somewhere.

[1061819510]

Now i only have show tech-support.txt , it has information about dir only this.

Maybe you can search it in the 'show tech' file by issue 'show bootflash:' command
