We have ACS 5.3 and Wireless Lan Controllers. We are doing MAC authentication for wireless clients. When MAC authentication was implemented for WLC, the format chosen for users was XX-XX-XX-XX-XX-XX. This has been working perfectly, but now we need to integrate some autonomous AP to ACS and problems has raised.
At initial tests we found that with the format we are using for users in ACS, authentication does not work. We did some traffic captures and found that Radius user-name attribute format was XXXXXXXXXXXX (no dots or dashes between MAC Address).
We also realized that through AP Web interface you are able to change the format for Called-Station-ID and Calling--Station-ID attributes, but changing these has no effect in user-name attribute.
So we are wondering if there is a way, probably in CLI, to change the format od user-name attribute, so AP sends it like XX-XX-XX-XX-XX-XX instead of XXXXXXXXXXXX.
Thanks a lot.
