Working with VSCs
VSC configuration options
5-14
High security/less performance: This option uses HMAC (Hash based message
authentication code) to ensure the data integrity and authenticity of each packet.
Performance is reduced due to the overhead needed to calculate HMAC.
Regardless of the security method used, the client tunnel does not encrypt the data
stream. To protect client traffic with encryption requires that client stations use WPA or VPN
software.
Under Wireless protection, enable WPA with the Terminate WPA at the controller.
This requires client stations that support WPA.
Use VPN-based authentication. See Securing wireless client sessions with VPNs on
page 16-3.
Quality of service
The quality of service (QoS) feature provides a number of different mechanisms to prioritize
wireless traffic sent to wireless client stations. See Quality of service (QoS) on page 5-37.
