packets (for example, ARP request and ICMPv6 Neighbor Solicit messages), and acts on
behalf of the station in delivering ARP replies. When the AP receives a broadcast
ARP/Neighbor Solicit request for a known host, the AP replies on behalf of the host. If the
AP receives a request for an unknown host, it forwards the request at the rate limit specified.
• Max Clients: This option limits the number of clients that can associate with this WLAN
per AP (default is 100). You can also limit the total number of clients that a specific AP (or
radio, on dual radio APs) will manage.
• 802.11d: Select this check box to enable this standard on this WLAN. 802.11d provides
specifications for compliance with additional regulatory domains (countries or regions) that
were not defined in the original 802.11 standard. Click this option if you are operating in
one of these additional regulatory domains.
• 802.11k Neighbor Report: Select this check box to enable 802.11k neighbor reports.
• Force DHCP: Enable this option to force clients to obtain a valid IP address from DHCP
within the specified number of seconds. This prevents clients configured with a static IP
address from connecting to the WLAN. Additionally, if a client performs Layer 3 roaming
between different subnets, in some cases the client sticks to the former IP address. This
mechanism optimizes the roaming experience by forcing clients to request a new IP
address.
• DHCP Option 82: Select the Enable DHCP Option 82 check box to enable this feature.
When this feature is enabled and an AP receives a DHCP request from a wireless client,
the AP will encapsulate additional information (such as VLAN ID, AP name, SSID and MAC
address) into the DHCP request packets before forwarding them to the DHCP server. The
DHCP server can then use this information to allocate an IP address to the client from a
particular DHCP pool based on these parameters.
• Client TX/RX Statistics: Select the Ignore statistics from unauthorized clients check
box if you do not want the controller to monitor traffic statistics for unauthorized clients.
• Inactivity Timeout: Select this check box and enter a value in seconds (60 to 600) after
which idle clients will be disconnected.
• Client Fingerprinting: By selecting this check box, the controller will attempt to identify
client devices by their operating system, device type and host name, if available. This
makes identifying client devices easier on the Dashboard, Monitor and Client Details
pages.
NOTE: Enabling this option for Kumo devices ensure that the client information is also
sent as a RADIUS attribute (access request ) for Hotspot WISPr WLANs.
• OFDM Only: Select the check box to force clients associated with this WLAN to use only
Orthogonal Frequency Division Multiplexing (OFDM) to transmit data. OFDM-only allows
the client to increase management frame transmission speed from CCK rates to OFDM
rates. This feature is implemented per WLAN and only affects the 2.4GHz radio.
• BSS Min Rate: Select this check box to set the bss rates of management frames from
default rates (CCK rates for 2.4G or OFDM rate – 6Mbps for 5G] to the desired rates. By
default, BSS Min Rate is disabled.
NOTE: OFDM-only takes higher priority than BSS-minrate. However, OFDM-only relies
on BSS-minrate to adjust its rate for management frames.
