1.升级LAP1142的前期准备

 

由于LAP1142无法获取到IP地址,将console线接到AP上,并且报告错误,日志如下

*Mar 1 00:00:44.491: %CDP_PD-2-POWER_LOW: All radios disabled - NEGOTIATEDWS-C2960S-48LPS-L (34bd.c8bc.5401)

*Mar 1 00:00:50.422: %CAPWAP-3-ERRORLOG: Not sending discovery request APdoes not have an Ip !!

*Mar 1 00:01:00.422: %CAPWAP-3-ERRORLOG: Not sending discovery request APdoes not have an Ip !!

 

2. 确定AP自身有问题,而非网络原因无法获得地址

 

2.1具体做法如下

先找到AP的网关和vlan,在AP所连接的上游交换机一路寻找,查看DHCP配置是否正确(网关,地址范围,vlanoption 43)等信息

 

2.2确定网络配置无误,将一台PC放到AP所在VLAN,能正确获得对应AP所在VLANIP地址

 

3. 1 LAP的镜像文件

  可从官方找到最新或近期的版本,注意是轻型AP的系统镜像,最好是查找官方关于APWLC的系统版本对照表,以保证兼容性

技术分享

3.2.准备好操作文档,由于此处是本地升级,需要配置PCIP地址,来传输AP的镜像文件。

 

3.3 升级开始,AP恢复模式下的IP地址为10.0.0.1/8,本地IP10.0.0.2/8

放在一个地址段或一个vlan即可,并关闭本地计算机计算机防火墙。

  开启在PC上开启tftp服务器,并将镜像文件放入TFTP指定目录

这里选择的是c1140-k9w8-tar.124-23c.JA4.tar

 

 c1140-k9w8-tar.124-23c.JA4.tar ----> c1140-k9w8-tar.default

 

重启AP,并按住mode

Base ethernet MACAddress: 00:1d:a1:ff:3c:dc
Initializing ethernet port 0...
Reset ethernet port 0...
Reset done!
ethernet link up, 100 mbps, full-duplex
Ethernet port 0 initialized: link is up
button is pressed, waitfor button to be released..(可以松开mode键)

button pressed for 29 seconds
process_config_recovery: set IP address and config to default 10.0.0.1
process_config_recovery: image recovery
image_recovery: Download default IOS tar image
tftp://255.255.255.255/c1240-k9w7-tar.default(根据实际情况修改)

剩下的过程就是AP重新安装系统的过程

升级成功结果
