WLAN Client Setting Deployment Considerations
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 underutilization 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 only allows packets from clients 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.
Enforce DHCP-Offer
Validation
Select the check box to enforce DHCP offer validation. The default setting is disabled.
Move Operation
Select the check box to enable the use of Fast Roaming (HFSR) for clients on this WLAN. This
feature applies only to certain Brocade client devices. This feature 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. 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 Brocade clients. The default setting is disabled.
Credential Cache Timeout
Set a timeout period for the credential cache in Days, Hours, Minutes or Seconds.
VLAN Cache Timeout
Set a timeout period for the VLAN cache in Days, Hours, Minutes or Seconds.
