WDS is a new feature for access points in Cisco IOS Software. WDS is a core functionality that enables other features such as Fast Secure Roaming, Wireless LAN Solution Engine (WLSE) interaction, and Radio Management. Relationships between the access points that participate in WDS must be established before any of these other WDS-based features can work. One of the primary purposes for WDS is to eliminate the need to have the authentication server validate user credentials every time and thereby reduce the time required for client authentications. Client authentication is defined by one or more client server groups on the WDS access points. When a client attempts to associate to an infrastructure access point, the infrastructure access point passes the user’s credentials to the WDS access point for evaluation. If it is the first time that the WDS access point has seen a given user’s credentials, it uses the authentication server to validate the credentials. The WDS access point then caches the user’s credentials, so it does not have to return to the authentication server when that user attempts authentication again (for example, reauthentication for rekeying, for roaming, or for when the user starts up the client device).
A: The WDS also runs on the WLSE in addition to the AP.
QUESTION NO: 7
A new Cisco Works Wireless LAN Sloutions Engine (WLSE) is being implemented into the TestKing network. This WLSE does NOT perform what network management function?
A. Aggregating SNMP and syslogs from its managed APs.
B. SNMP queries of the APs
C. The aggregation of Radio Management data
D. CDP Discovery
E. The WLSE performs none of the above functions.
CiscoWorks WLSE may be transparently integrated with other network management systems, operations support systems, and CiscoWorks applications through syslog messages, Simple Network Management Protocol (SNMP) traps, and an Extensible Markup Language (XML) interface. Although the WLSE can be used with Syslog and SNMP servers, it can not be used as a Syslog or SNMP server. Syslog and SNMP messages can not be effectively sent to the WLSE from the access points. Incorrect Answers: B. One of the tools available via the WLSE is the SNMP Query Tool. This tool allows you to find the value of a specified SNMP variable. Normally, this tool is used under the direction of Cisco TAC when they are assisting you with troubleshooting a problem.
C. Following are some of the WLSE radio management features that are supported: Radio Monitoring, AP Radio Scan, Client Walkabout, RMAssisted Configuration, Self Healing, Auto Re-Site Survey, Location Manager.
D. By default, the WLSE runs a CDP discovery every 24 hours.
QUESTION NO: 8 An SSG is being utilized within the TestKing Public Wireless LAN. What best describes the function of an SSG in a Public Wireless LAN (PWLAN)?
A. The SSG provides connectivity, client address management, security services, and routing across a WAN from each wireless access point to the service provider data center.
B. The SSG providees subscriber authentication and maintains the state of all users in the hotspot.
C. The SSG is an http proxy that provides captive portal capabilities to the service provider hot spot network.
D. ‘The SSG is a central device that allows wireless clients to cross layer three subnets with sub-second roam times.
E. The SSG provides central management for the PWLAN hotspot network
Access control of the PWLAN is based on the extremely flexible Cisco IOS Service Selection Gateway (SSG) technology that is now available across a broad range of platforms, including the Cisco 2651XM Router , Cisco 2691 Router, Cisco 3725 Router, Cisco 3745 Router, Cisco 7200 Series, and Cisco 7301 Router. Together with the Cisco CNS Subscriber Edge Services Manager (SESM), the Cisco SSG provides subscriber authentication, service selection, service connection, and accounting capabilities to subscribers of Internet and intranet services.
The Cisco CNS SESM works with the Cisco SSG to provide complete control over the subscriber experience, supporting customization and personalization based on device, client, location, service, and other criteria to offer higher value to end users and maximize service and advertising revenue. The Cisco SSG access control platform can proxy EAP authentication messages from hot-spot access points and automatically create user sessions upon successful EAP authentication, thereby eliminating the need for “double authentication,” first at Layer 2 with 802.1x/EAP and then at Layer 3 through the Web portal. This feature allows an operator to take advantage of the Cisco SSG for centralized accounting record generation for both 802.1x/EAP and Web-authenticated users.
QUESTION NO: 9 In the Wireless TestKing network, Layer 2 Fast Secure Roaming technology has been implemented. Layer 2 Fast Secure Roaming is enabled by what type of device?
A. An ACS or other AAA server
B. A device running as a WDS
C. The Ethernet switch
D. The WLSE
E. A firewall
In Layer 2 Fast Secure Roaming, the Wireless Domain Services (WDS) act as a central authentication entity that supports a fast client rekey, rather than requiring a full RADIUS reauthentication each time the client roams. All access points and clients in a L2 domain 802.1X authenticate to a RADIUS server via the WDS that performs the role of 802.1X authenticator. Because all clients and access points authenticate via the WDS, the WDS is able to establish shared keys between itself and every other entity in the L2 domain. These shared keys enable CCKM fast secure roaming. The following diageam illustrates access points and clients authenticating to WDS.
The WDS function is written in Cisco IOS Software and initially runs on Cisco IOS Software on Cisco Aironet access points only. In the future, WDS be available in Cisco router and switch infrastructure products. At least one WDS is required per L2 domain. The CCKM architecture supports WDS redundancy via a MAC-layer multicast primary WDS election process. If redundant WDS are configured, the WDS with the highest priority is elected to be the primary WDS. If equal or no priorities are configured, a primary is dynamically determined. Redundancy provides a cold backup. If the primary WDS fails, all authenticated clients continue to operate, until a roaming event occurs, at which point the client completes a full initial authentication to the RADIUS server, via the backup WDS. All access points in a L2 domain dynamically learn the address of the active WDS via an L2 multicast. The address of the WDS is not configured in any access point.
