Our company has 17 access points (1200) connected in our meeting rooms. Recently we purchased an ACS appliance to authenticate this access points. I would like to do this using uername&password(local database) and mac address authentication. is t possible ? or whether I have to use a certification server for this purpose.? Configuring each access point with certicates is a difficult task .one engineer told me that cisco acs appliance dosent support username password and mac address combination. please clarify. If there is a documentation for this please referto the same too.
