WLC和思科的路由器交换机不同，Cisco的WLC采用的是AireOS.

如下操作，是如何查看coredump文件，并且如何导出：

1、通过命令show coredump summary 查看

(WiSM-slot8-1) >show coredump summary

Core Dump is enabled

FTP Server IP....................................  128.172.193.253
FTP Filename.....................................  Poca-WiSM-1_cd
FTP Username.....................................  mcdaviddj
FTP Password..................................... *********

Core Dump file on flash:

SW Version....................................... 7.3.101.0
Time  Stamp....................................... Mon Apr 15 15:00:51 2013
File  Size........................................ 62563632
File Name  Suffix................................._7.3.101.0_Poca-WiSM-1_1366052451.gz  ===> Core Dump of crash stored in Flash

2、导出core dump

使用TFTP工具：

(Cisco Controller) >transfer upload datatype coredump
(Cisco  Controller) >transfer upload filename <desired filename>
(Cisco  Controller) >transfer upload mode <tftp/ftp>
(Cisco Controller)  >transfer upload serverip <ip>
(Cisco Controller) >transfer  upload start

使用FTP工具还需要用户密码

(Cisco  Controller) >transfer upload username username
(Cisco Controller)  >transfer upload password password
(Cisco Controller) >transfer upload  port port （默认21）

其他辅助：例如如果有外部的日志服务器，可以导出WLC的日志文件，可以查看对应的log。
