Generating CSR file from Cisco AIR-CT2504 Wireless Lan Controller


How do I generate a CSR file from the Cisco AIR-CT2504 WLC?

I would need this file so that our CA team can generate a certificate and import it to the WLC.

Any information will do.
Many thanks.

Generating a CSR for a cert is not done on the WLC itself. Step-by-step instructions on doing this for Cisco WLC can be found at
Install openSSL on your desktop computer

Note: OpenSSL 0.9.8 is required as the WLC does not currently support OpenSSL 1.0.

In Windows, by default, openssl.exe is located at c:\openssl\bin

OpenSSL>req -new -newkey rsa:1024 -nodes -keyout WLCcertname.pem -out WLCcertname.pem

go through prompts

send to CA team and upload to the WLC via TFTP

Hello, I tried the openSSL.exe but after i type in the line,
req -new -newkey rsa:1024 -nodes -keyout WLCcertname.pem -out WLCcertname.pem

it only shows
unable to load config info from c:openssl/ssl/openssl.cnf error in req
