Each WLAN can maintain its own client setting configuration. These settings include wireless client inactivity timeouts and broadcast configurations.
To define a WLAN's unique client support configuration:
| Enable Client-to-Client Communication | Select this option to enable client to client communication within this WLAN. The default is enabled, meaning clients are allowed to exchange packets with other clients. It does not necessarily prevent clients on other WLANs from sending packets to this WLAN, but as long as this setting also disabled on that WLAN, clients are not permitted to interoperate. |
| Wireless Client Power | Use this parameter to set the maximum transmit power (between 0 - 20 dBm) communicated to wireless clients for transmission within the network. The default value is 20 dBm. |
| Wireless Client Idle Time | Set the maximum amount of time wireless clients are allowed to be idle within this WLAN. Set the idle time in either Seconds (60 - 86,400), Minutes (1 - 1,440), Hours (0 - 24), or Days (0 - 1). When this setting is exceeded, the client is no longer able to access resources and must re-authenticate. The default value is 1,800 seconds. |
| Max Firewall Sessions per Client | Select this option to set the maximum amount of sessions (between 10 - 10,000) clients within the network over the Firewall. When enabled, this parameter limits the number of simultaneous sessions allowed by the Firewall per wireless client. This feature is disabled by default. |
| Max Clients Allowed Per Radio |
Use the spinner control to set the maximum number of clients (from 0 - 256) allowed to associate to each radio within this WLAN. The default setting is 256. |
| Radio Resource Measurement | Select this option to enable radio resource measurement
capabilities (IEEE 802.11k) on this WLAN. 802.11k improves how traffic
is distributed. In a WLAN, each device normally connects to an access
point with the strongest signal. Depending on the number and locations
of the clients, this arrangement can lead to excessive demand on one
access point and under-utilization for others, resulting in
degradation of overall network performance. With 802.11k, if the access point with the strongest signal is loaded to its capacity, a client connects to a underutilized access point. Even if the signal is weaker, the overall throughput is greater since it's an efficient use of the network's resources. This setting is disabled by default. |
| Radio Resource Measurement Channel Report | Select this option to enable radio resource measurement channel reporting (IEEE 802.11k) on this WLAN. This setting is disabled by default. |
| Enforce Client Load Balancing |
Select the check box to distribute clients evenly amongst associated access point radios. This feature is disabled by default. Loads are balanced by ignoring association and probe requests. Probe and association requests are not responded to, forcing a client to associate with another access point radio. |
| Enforce DHCP Client Only | Select the check box to enforce that the firewall allows packets from clients only if they used DHCP to obtain an IP address, disallowing static IP addresses. This feature is disabled by default. |
| Proxy ARP Mode | Use the drop-down menu to define the proxy ARP mode as either Strict or Dynamic. Proxy ARP is the technique used by the access point to answer ARP requests intended for another system. By faking its identity, the access point accepts responsibility for routing packets to the actual destination. Dynamic is the default value. |
| Proxy ND Mode | Use the drop-down menu to define the proxy ND (neighbor discovery) mode for WLAN member clients as either Strict or Dynamic. ND Proxy is used in IPv6 to provide reachability by allowing the a client to act as proxy. Proxy certificate signing can be done either dynamically (requiring exchanges of identity and authorization information) or statically when the network topology is defined. Dynamic is the default value. |
| Enforce DHCP-Offer Validation | Select the check box to enforce DHCP offer validation. The default setting is disabled. |
| Move Operations |
Select the check box to enable the use of HFSR (Hyper-Fast Secure Roaming) for clients on this WLAN. This feature applies only to certain client devices and is disabled by default. |
| Smart Scan | Enable a smart scan to refine a clients channel scans to just a few channels as opposed to all available channels. This feature is disabled by default. |
| Symbol Information Element | Select the check box to support the Symbol Information Element with legacy Symbol Technology clients, thus making them optimally interoperable with the latest Extreme Networks access points. The default setting is enabled. |
| WMM Load Information Element | Select the check box to support a WMM Load Information Element in radio transmissions with legacy clients. The default setting is disabled. |
| Scan Assist | Enable scan assist to achieve faster roams on DFS channels by eliminating passive scans. Clients would get channel information directly from possible roam candidates. This setting is disabled by default. |
| FT Aggregate | Enable FT (fast transition) aggregate to increase roaming speed by eliminating separate key exchange handshake frames with potential roam candidates. Enable fast transition to complete an initial FT over DS handshake with multiple roam candidates (up to 6) at once, eliminating the need to send separate FT over DS handshakes to each roam candidate. This setting is disabled by default. |
| Channel Info Interval | Configure the channel information interval to periodically retrieve channel information directly from potential roam candidates without making a scan assist request. |
| Enable | Enable this setting to inform an access point when it experiences a coverage hole (area of poor wireless coverage). This setting is disabled by default. |
| Use 11k Clients | Optionally enable this setting to also use 802.11k-only-capable clients to detect coverage holes. This is a reduced set of coverage hole detection capabilities (only standard 11k messages and behaviors). This setting is disabled by default. |
| Threshold | Use the spinner control to set the access point signal strength (as seen by the client) below which a coverage hole incident is reported. The threshold can be set from -80 to -60. |
| Offset | Use the spinner control to set the offset added to the threshold to obtain the access point signal strength (as seen by the client) considered adequate. The offset can be set from 5 to 20. |
| Enable | Select this option to include the AP-Attributes information element in the beacon. The information element helps clients recognize which wing-extensions are supported by the AP. This setting is enabled by default. |
| Include Hostname | Select this option to include the AP's hostname in the AP-Attributes information element. This setting is disabled by default. |
| Credential Cache Timeout | Set a timeout period for the credential cache in Days (0-1), Hours (0-24), Minutes (1-1440), or Seconds (60-86,4000). The default setting is 1 hour. |
| VLAN Cache Timeout | Set a timeout period for the VLAN cache in Days (0-1), Hours (0-24), Minutes (1-1440), or Seconds (60-86,4000). The default setting is 1 hour. |
Use the Inactivity Time Out field to define the inactivity timeout specific to T5 clients. Set the maximum amount of time T5 clients are allowed to be idle within this WLAN. Set the idle time in either Seconds (60 - 86,400), Minutes (1 - 1,440), Hours (0 - 24) or Days (0 - 1). When this setting is exceeded, the client is no longer able to access resources and must re-authenticate. The default value is 1,800 seconds.
A T5 controller, once enabled as a supported external device, can provide data to WiNG to assist in a T5‘s management within a WiNG supported subnet populated by both types of devices. The CPEs (Customer Premises Equipments) are the T5 controller managed radio devices. These CPEs use a DSL (Digital Subscriber Line) as their high speed Internet access mechanism using the CPE‘s physical wallplate connection and phone jack.
