WLC和思科的路由器交换机不同,Cisco的WLC采用的是AireOS.
如果WLC crash或无故重启,可以尝试采集如下信息:
AireOS WLC version 8.0.140.0 or higher
WLC Model 2504/5508/5520/7500/8500/8540/WISM WLC>config paging disableWLC>show techWLC>show memory hisWLC>show memory mbufWLC>show coredump summaryWLC>config paging enable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 summaryCore Dump is enabledFTP Server IP.................................... 128.172.193.253FTP Filename..................................... Poca-WiSM-1_cdFTP Username..................................... mcdaviddjFTP Password..................................... *********Core Dump file on flash:SW Version....................................... 7.3.101.0Time Stamp.......................................

2、导出core dump
使用TFTP工具:
(Cisco Controller) >transfer upload datatype coredump(Cisco Controller) >transfer upload filename(Cisco Controller) >transfer upload mode (Cisco Controller) >transfer upload serverip (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。 操作示例参考:
