AP 不能加入WLC 的非常常见的一种故障,引起这种故障的原因可能非常多种类,这种提供一些排错步骤,供大家参考!
大家也可以共享更多的案例或者逻辑等!
① AP 能获取IP地址,且AP获取的IP地址与WLC属于相同网段&能通信(PC去ping WLC)

②查看AP IOS 与WLC 的IOS是否兼容,很重要
③看时间,WLC的时间如果与现在的时间差别太大会导致AP无法加入WLC, 时间配置一致,目的是让证书时间一致,不至于一个过期,一个不过期
④ 看log,最好、最直接查找原因
⑤show lwapp ip config 查看AP是否原来在其他地方有flexconnect的配置还保留
clear lwapp private-config 清除配置
lwapp ap ip address 10.77.244.199 255.255.255.224
lwapp ap ip default-gateway 10.77.244.220
lwapp ap controller ip address 172.16.1.50
show capwap ip config
show lwapp ip config
⑥ 如果客户公司很多人使用无线,有个别连接不上,或者连接上了显示感叹号,可能是IP地址不够导致的。
⑦ PoE供电,如果交换机不稳定会导致AP不稳定
⑧ WLC 跟AP 都可以查看日志
⑨ 单台AP连接的客户端较多导致故障
(10) 查看AP功率大小,如果不是最高,可以适当提高AP功率,看是否有改善。
Problem 1: The controller time is outside the certificate validity interval

Problem 2: Mismatch in Regulatory domain

Problem 3: Error Message AP cannot join because the maximum number of APs on interface 2 is reached

Problem 4: With SSC APs, the SSC AP policy is disabled

Problem 5: AP authorization list enabled on the WLC; LAP not in the authorization list

Problem 6: The SSC public key−hash is wrong or missing

Problem 7: There is a certificate or public key corruption on the AP

Problem 8: The controller might be working in Layer 2 mode

Problem 9: You receive this error message on the AP after conversion to LWAPP

Problem 10: Controller receives AP discovery message on wrong VLAN (you see the discovery message

debug, but not response)

Problem 11: 1250 LAP Not Able to Join WLC

Problem 12: AP Not Able to Join the WLC, Firewall Blocking Necessary Ports

Problem 13: Duplicate IP address in the network

Problem 14: LWAPP APs do not join WLC if network MTU is less than 1500 bytes

Problem 15: 1142 series LAP not joining the WLC, Error message on WLC : lwapp_image_proc: unable

to open tar file

Problem 16: 1000 series LAPs not able to join the Wireless LAN controller, WLC runs version 5.0

Problem 17: LAPs with Mesh image not able to join WLC

Problem 18: Error Message − Dropping primary discovery request from AP XX:AA:BB:XX:DD:DD −
