[C9800CL][#4]-AP Join Process - Manual Method

안녕하세요. 

 

오늘은 AP를 직접 IP주소랑 Default Gateway를 설정하고 WLC에 Manuall하게 등록해 보겠습니다. 

 

 

테스트 IP주소 입니다. 

AP IP: 192.168.200.200

AP GW: 192.168.200.181

WLC: 192.168.100.182

 

AP주소를 초기에 설정시 아래와 같이 Username/Passowrd는 Cisco 입니다. 

Username: Cisco Password: Cisco APC884.A1CC.2F48>en Password: Cisco APC884.A1CC.2F48#

 

1. AP에 IP주소랑 Gateway를 설정 합니다. 

capwap ap ip 192.168.200.200 255.255.255.0 192.168.200.181

 

IP주소를 입력하면 CAPWAP discovery 패킷을 Broadcase를 사용 해서 전송 하고 있습니다.

하지만 AP랑 WLC가 같은 L2도메인 안에 없기 때문에, WLC 찾을수 없습니다. 

[*12/24/2024 10:37:43.9513] Check whether client_ip_table entry need to be cleared 0 [*12/24/2024 10:37:43.9613] Clearing client entry [*12/24/2024 10:37:46.6105] AP IPv4 Address updated from 0.0.0.0 to 192.168.200.200 [*12/24/2024 10:37:46.6305] send CAPWAP ctrl msg to the socket: Socket operation on non-socket [*12/24/2024 10:37:46.6305] dtls_init: Use MIC certificate [*12/24/2024 10:37:46.9404]  [*12/24/2024 10:37:46.9404] CAPWAP State: Init [*12/24/2024 10:38:02.6655] PNP:Server not reachable, Start CAPWAP Discovery [*12/24/2024 10:38:02.6855]  [*12/24/2024 10:38:02.6855] CAPWAP State: Discovery [*12/24/2024 10:38:02.8954] Discovery Request sent to 255.255.255.255, discovery type UNKNOWN(0) [*12/24/2024 10:38:02.9054]  [*12/24/2024 10:38:02.9054] CAPWAP State: Discovery

 

2. AP Hostname를 변경하고 WLC주소를 입력합니다.

APC884.A1CC.2F48#capwap ap hostname AP01 APC884.A1CC.2F48#capwap ap primary-base WLC01 192.168.100.182

 

아래처럼 WLC가 Discovery Response 패킷을 전송하였습니다. 

그리고 Found Confirued WLC01 이후 DTLS setup 시작 합니다.

3. 이번에는 WLC GUI에 접속해서 AP를 확인해보겠습니다.

Monitoring ->Wireless ->AP statistics 클릭 합니다. 

 

아래 사진처럼 AP01이 WLC에 등록이 되었고 Admin Status를 표시면 초록색으로 정상적입니다. 

 

테스트를 위해서 WLC GUI에서 AP를 Reset 합니다.

 

AP를 더블클릭 합니다. 

 

 

 

지금까지 [C9800CL][#3]-AP Join Process - Manual Method 글을 읽어주셔서 감사합니다.

다음글은 DHCP option43를 이용해서 AP를 WLC에 등록 하는 글을 다루겠습니다.
