MSM7xx Controllers Configuration Guide v6.4.0

Terminate WPA at the controller
This feature is intended for low throughput applications, such as supporting point of sale (POS)
terminals.
Enabled
When enabled, the controller acts as the termination point for all WPA/WPA2 sessions. This
enables the network to meet PCI (Payment Card Industry) compliance supporting the connection
of point of sale (POS) terminals.
Disabled
When disabled, WPA/WPA2 sessions are terminated at the AP. This means that wireless
communication between the client station and AP is secure, but traffic between the AP and
controller is not. This is normally sufficient since outsiders do not have access to your wired
network. However, in a public venue such as a hotel, if the public has access to your wired
network, it may be necessary to provide end-to-end security for certain client stations, such as
POS terminals.
NOTE:
• This feature supports a maximum of 10 sessions on the MSM720 and 50 sessions on the
MSM760, MSM765 zl, and MSM775 zl.
• A VSC that is configured with the option Terminate WPA at the controller cannot be bound
to an HP 517 or an AP group that contains an HP 517.
WEP
This option provides support for users using WEP encryption.
NOTE: When the radio used by a VSC is configured to support 802.11n or 802.11ac, and the
VSC is configured to use WEP, the VSC can only support legacy a/b/g traffic. (Except on the
MSM422, where WEP is not supported when the radio is configured for 802.11n.)
Key source
This option determines how the WEP keys are generated: dynamic or static key.
• Dynamic: This is a dynamic key that changes each time the user logs in and is authenticated.
