Parameter Description
Delimiter character Specify a character ( for example, colon or dash) as a delimiter for the MAC address string.
When configured, the W-IAP will use the delimiter in the MAC authentication request. For
example, if you specify colon as the delimiter, MAC addresses in the xx:xx:xx:xx:xx:xx
format are used. If the delimiter is not specified, the MAC address in the xxxxxxxxxxxx
format is used.
NOTE: This option is available only when MAC authentication is enabled.
Uppercase support Set to Enabled to allow the W-IAP to use uppercase letters in MAC address string for MAC
authentication.
NOTE: This option is available only if MAC authentication is enabled.
Authentication server To configure an authentication server, select any of the following options:
