+# NAS-Identifier string for RADIUS messages. When used, this should be unique
+# to the NAS within the scope of the RADIUS server. Please note that hostapd
+# uses a separate RADIUS client for each BSS and as such, a unique
+# nas_identifier value should be configured separately for each BSS. This is
+# particularly important for cases where RADIUS accounting is used
+# (Accounting-On/Off messages are interpreted as clearing all ongoing sessions
+# and that may get interpreted as applying to all BSSes if the same
+# NAS-Identifier value is used.) For example, a fully qualified domain name
+# prefixed with a unique identifier of the BSS (e.g., BSSID) can be used here.
+#
# When using IEEE 802.11r, nas_identifier must be set and must be between 1 and
# 48 octets long.
+#
+# It is mandatory to configure either own_ip_addr or nas_identifier to be
+# compliant with the RADIUS protocol. When using RADIUS accounting, it is
+# strongly recommended that nas_identifier is set to a unique value for each
+# BSS.

##### TESTING OPTIONS #########################################################
#
# The options in this section are only available when the build configuration
# - is not the same as the MAC address of the radio
# - is not the same as any other explicitly specified BSSID
#
+# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
+# hostapd to use the driver auto-generated interface address (e.g., to use the
+# exact MAC addresses allocated to the device).
+#
# Not all drivers support multiple BSSes. The exact mechanism for determining
# the driver capabilities is driver specific. With the current (i.e., a recent
# kernel) drivers using nl80211, this information can be checked with "iw list"
