Authentication Options
Authentication Type Defines the type of authentication flow for the WLAN.
NOTE
Authentication types such as WeChat, Web Authentication and Guest Access are not supported by APs in IPv6 mode.
Select the required option:
  • Standard Usage—This is a regular WLAN suitable for most wireless networks.
  • Hotspot (WISPr)—Click this option if want to use a hotspot service (use this type for external captive portal workflows) or WISPr.
    NOTE
    Hotspot (WISPr) applies to WLAN traffic that is tunneled and not tunneled.
  • Guest Access—Click this option if you want guest users to use this WLAN. After you complete creating this WLAN for guest access, you can start generating guest passes.

    For more information about Hotspot 2.0 online signup, see the Hotspot 2.0 Reference Guide for this release.

  • Web Authentication—Click this option if you want to require all WLAN users to complete a web-based logon to this network every time they attempt to connect.
  • Hotspot 2.0 Access—Click this option if you want a Hotspot 2.0 operator profile that you previously created to use this WLAN. See the Hotspot 2.0 Reference Guide for this release.
  • Hotspot 2.0 Onboarding—Click this option if you want to use this WLAN for Hotspot 2.0 onboarding. See the Hotspot 2.0 Reference Guide for this release for more information. Hotspot 2.0 onboarding allows for Open and 802.1x EAP authentication methods.
  • WeChat—Click this option if you want the WLAN usage through WeChat.
Authentication Options
Method Specifies the authentication mechanism. Select the following option:
  • Open (Default)—No authentication mechanism is applied to connections. If WPA or WPA2 encryption is used, this implies WPA-PSK authentication.

    If you clicked Web Authentication in Authentication Type, Open is the only available authentication option, even though PSK-based encryption can be supported.

  • 802.1x EAP—A very secure authentication/encryption method that requires a back-end authentication server, such as a RADIUS server. Your choice mostly depends on the types of authentication the client devices support and your local network authentication environment. If you select Enable RFC Location Delivery Support for Authentication & Accounting Server, enter the Operator Realm.

    Selecting the authentication method as Hotspot (WISPr), also allows you to select 802.1x EAP as an authentication option. This enables a two-step authentication method when shared and pre-authenticated devices are used, or when user equipment is shared among multiple users. The device access is successful when both authentication processes are completed successfully - 802.1x EAP authentication first, followed by Hotspot (WISPr) authentication.

  • 802.1x EAP with MAC address—Selecting this option indicates that the 802.1x EAP and MAC address authentication methods must both pass for a user to successfully authenticate. First, MAC address authentication is verified, if that passess, 802.1x EAP authentication is processed. After this two authentication methods succeed, the user equipment gains access to the WLAN. Authentication is done by a back-end RADIUS server.

    When this authentication method is selected, the MAC Authentication and MAC Address Format fields will be shown within the Authentication Options section.

  • MAC Address—Authenticate clients by MAC address.
    • MAC Authentication—Requires a RADIUS server and uses the MAC address as the user logon name and password.
      • Select Use user defined text as authentication password (default is device MAC address) and enter the format.
    • MAC Address Format—Choose the MAC address format from teh drop-down.
Encryption Options
Method Specifies the encryption method.

WPA and WPA2 are both encryption methods certified by the Wi-Fi Alliance; WPA2 with AES is the recommended encryption method. The Wi-Fi Alliance will be mandating the removal of WEP due to its security vulnerabilities, and Ruckus recommends against using WEP if possible.

Advanced Options
User Traffic Profile Defines the traffic policy that will be applied to users on this WLAN. The default UTP allows all with no rate limits. UTPs can define rate limits as well as L3-7 ACLs and policies. Select the required option.
L2 Access Control Enables the WLAN to blacklist or whitelist a specific set of MAC addresses based on a L2 access control policy. Select the required option.
OS Policy Enables the WLAN to apply a unique policy to a device based on OS type. Use a precedence profile to determine whether a role-based, AAA-based, or OS-based policy will take precedence. Select the required option.
Application Recognition and Control Enables DPI-based L7 application recognition, and if enabled, an application control policy. Recognition and control are performed on the AP. Select the Enable check box.
URL Filtering Enables URL filtering on the WLAN controller to block or allow access to specific web sites or web pages. Select the Enable check box.
Client Fingerprinting Enables the AP to attempt utilize DHCP fingerprinting to identify client devices by their operating system, device type, and host name. Select the check box.
Access VLAN Tags the WLAN traffic with a VLAN ID between 2-4094. By default, all client traffic will be assigned to the native (untagged) VLAN on the AP's Ethernet port, which we represent as VLAN ID 1. Select the check box and enter the VLAN ID.
Hotspot 2.0 Onboarding Allows devices to connect to a WiFi network automatically, where in the service providers engage in roaming partnerships to provide seamless access to WiFi networks. The devices are authenticated using credentials or certificates. Select the check box to allow Hotspot 2.0 Onboaring for the WISPr WLAN.
Hide SSID Removes the SSID from Beacon frames. By removing the SSID, in most cases, clients will not show this SSID in their scan list unless the device is already configured to connect. This can simplify the network decision for an end user. Select the check box.
Client Load Balancing Disables client load balancing on this WLAN if the option is selected. Select the check box to disable client load balancing on this WLAN.
Proxy ARP Enables proxy ARP. When proxy ARP is enabled on a WLAN, the AP provides proxy service for stations when receiving neighbor discovery 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. Select the check box.
MAX Clients Limits the number of clients that can associate with this WLAN per AP radio (default is 100). Every connection attempt after this max value will not be permitted to connect. Enter the number of clients allowed.
802.11d Adds additional regulatory information to AP beacons and probe responses. This compliance information provides country-specific guidance like permitted channels and transmit power, to ensure that the devices operate within the legal boundaries of the country. 11d is helpful for many devices that cannot independently determine their operating country. Select the check box to enable this option.
802.11k Neighbor Report Enhances roaming by providing a list of neighbor APs to the client device. APs build a neighbor AP list via background scanning, and when the client plans to roam, it will request this list from the AP. This list is then used to perform efficient scanning to find a roaming candidate. Select the check box.
Force DHCP Requires the 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. Select the check box.
DHCP Option 82 Enables an AP to 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. Select the check box.
DHCP Option 82 Format

Enables an AP to 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.

Choose the required option:
  • Default
  • Option-A
  • Option-B
DTIM Interval

Indicates the frequency at which the DTIM (Delivery Traffic Indication Message) will be included in Beacon frames.

Enter the frequency number.

Range: 1 through 255.

Directed MC/BC Threshold Defines the per radio client count at which an AP stops converting group-addressed data traffic to unicast. However, the Directed Threshold logic is only one part of the access points' multicast handling logic, which means there may be other factors that determine whether a frame is transmitted as unicast or multicast. APs support a feature called Directed Multicast (configurable only on AP CLI, enabled by default), which adds additional logic to the multicast flow. If Directed Multicast is disabled, the AP uses the Directed Threshold as the only criteria to determine whether to transmit a multicast packet as unicast. However, when Directed Multicast is enabled, the flow is changed. Directed Multicast is a feature that checks to see if a multicast packet is well-known or not. For well-known multicast packets, for example: Bonjour, uPNP, most IPv6 link- and node-local, Spectralink, the AP still applies the directed-threshold logic to determine conversion to unicast. For non well-known types, the AP monitors and maintains a database of client subscriptions using IGMP and MLD. If associated clients are subscribed to the multicast stream, then the AP always converts these packets to unicast, regardless of the Directed Threshold configuration. If there are no clients subscribed to the multicast stream, the AP drops these packets. It is important to be aware of this behavior when validating multicast operation in a deployment. Enter the client count number.

Range: 0 through 128.

Client tx/Rx Statistics Stops the controller from monitoring traffic statistics for unauthorized clients. Select the check box.
Inactivity Timeout Indicates the duration after which idle clients will be disconnected. Enter the duration in seconds.
OFDM Only Disconnects 802.11b devices to the WLAN and all devices are forced to use higher data rates for more efficient airtime usage. This setting only affects the 2.4GHz radio. OFDM is used by 802.11a/g/n/ac, but is not supported by 802.11b. Select the check box.
BSS Min Rate Forces client devices to both be closer to the AP and to use higher, more efficient rates when you increase the BSS min rate above the default (all rates) setting. The BSS minimum rate is the lowest data rate supported on the WLAN. When OFDM-only is enabled, it takes higher priority than BSS min rate settings. Select the option.
Mgmt Tx Rate Sets the transmit rate for management frames type such as beacon and probes. Select the value.
Service Schedule Controls when the WLAN service is active. The purpose of this setting is to automatically enable or disable a WLAN based on a pre-determined schedule. By default, the service is Always On. Always Off can be checked in order to create a WLAN and apply it, but prevent it from advertising until ready. The"specific" setting allows a configurable schedule based on time of day and days of the week.
NOTE
When a service schedule is created it is saved by the SZ and AP using the browser's time zone. When it is enforced bu the AP, the AP will enforce it according to the time zone of the browser when it was configured.
Choose the option:
  • Always On
  • Always Off
  • Specific and select a schedule profile from the drop-down list.
Band Balancing Disables band balancing only for this WLAN, if you select the check box. Select the Disable band balancing for this WLAN service check box.
Qos Map Set

Reprioritizes downlink packets based on the configured mappings. When an AP receives a downlink packet, it checks the existing DSCP (L3 QoS) marking, compares it to this map set and then changes the user priority (L2 QoS) values for transmission by the AP.

TO configure this feature, select the User Priority (UP) from the table (0-7) and configure the DSCP (0-64) range that will be mapped to this UP.

Exceptions can also be added such that the original DSCP and UP tagging are preserved the honored by the AP.

Select Enable QOS Map Set.
SSID Rate Limiting Enforces an aggregate rate limit for all users of the WLAN. The purpose of this feature is to prevent the combined throughput form all users of an SSID from exceeding this threshold. This feature is different from per-user rate limiting, which enforces the same rate limit for each individual device. Select Uplink and Downlink check boxes and enter the limiting rate in mbps respectively. Range: 1 mbps through 200 mbps.
DNS Server Profile Allows the AP to inspect DHCP messages and overwrite the DNS server(s) with the DNS server configured in this profile. This allows for policy-based DNS application in which unique users/roles should use a different DNS server than others. Select a profile from the drop-down menu. Select Disable from the drop-down menu if you want to disable the DNS Server profile for the WLAN service.
Precedence Profile Defines the relative policy assignment priority for some specific settings. For example, if a WLAN is configured to use VLAN 10, and a AAA/role policy is configured for VLAN 20, and a device OS policy is configured for VLAN 30, and a user/device connects to the WLAN matching all of these policies, which VLAN should be assigned? The precedence policy determines which setting takes priority. Select the option.
Client Flow Data Logging Sends a log message with source MAC, destination MAC, source IP, destination IP, source port, destination port, L4 protocol and AP MAC of each packet session to the external syslog server. This function is provided by the AP syslog client (not the SZ's syslog client), which must be enabled at the zone level in order to support this client flow logging. Select the check box to log the client-flow data to the external syslog server. Then enable AP syslog functionality from the Zone settings.
Transient Client Management Avoids transient clients from joining the network. Select the Enable Transient Client Managementcheck box and set the following parameters:
  • RSSI threshold—Enter the Client RSSI threshold to allow joining. Range: -60 through -90 dBm.
  • Join wait time—Enter the wait time before a client can be permitted to join. Range: 1 through 60 secs.
  • Join expire time—Enter the time during which a rejoin request is accepted without delay. Range: 1 through 300 secs.
  • Join wait threshold—Enter the number of join attempts after which a client is permitted to join even before the join wait time expires.
NOTE
Ensure that Background Scan is enabled.
Airtime Decongestion Mitigates air-time congestion caused by management frames in high density deployments. Select the check box.
NOTE
You can also edit, clone and delete WLANs by selecting the options Configure, Clone and Delete respectively, from the Wireless LANs page.
