Cisco MDS交换机 log error

一、故障现象

2025 Apr 15 16:07:15 MDS %VSHD-3-VSHD_SYSLOG_EOL_ERR: EOL function acl_cli_show_region_info from library libacl.so exited due to Signal 11
2025 Apr 15 16:09:12 MDS %SYSMGR-2-LAST_CORE_BASIC_TRACE: : PID 27393 with message non-sysmgr(non-sysmgr) crashed, core will be saved .

二、排错思路

2.1 查看设备版本

“show version”

Software
BIOS: version 3.1.0
kickstart:version 8.2(1)
system:version 8.2(1)
kickstart image file is: bootflash:///m9700-sf3ek9-kickstart-mz-npe.8.2.1.bin
system image file is: bootflash:///m9700-sf3ek9-mz-npe.8.2.1.bin

2.2 查看cpu使用率

`show processes cpu history`

Internal error during command execution (11 8b)

三、结论

通过以上查询的信息得知，当前设备版本为8.2(1)，CPU使用率在20%以下。结合故障log日志显示内容来看，符合当前在8.2(1)版本中上面的一个已知的bug，BUG相关链接如下:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvh99074

该问题会在8.3(1)以上版本会修复，当前并无业务影响。

鉴于当前交换机版本，推荐升级版本至8.4(2f)。
