If guest traffic is tunneled to the unsecured network area, where do guest clients get an IP address? A. Guest traffic is transported within the enterprise at Layer 3 via EoIP. Therefore, the first point at which Dynamic Host Configuration Protocol (DHCP) services can be implemented is locally on the guest anchor controller, or the guest anchor controller can relay client DHCP requests to an external server. This is also the method by which Domain Name System (DNS) address resolution is handled. Q. How many Ethernet over IP (EoIP) tunnels can be terminated on a guest anchor controller? A. One guest anchor controller can terminate up to 71 EoIP tunnels from internal WLAN controllers. This capacity is the same across any model of the Cisco Wireless LAN Controller. More than one guest anchor controller can be configured if additional tunnels are required. EoIP tunnels are counted per WLAN controller, independently of the number of tunneled WLANs or Secure Set Identifiers (SSIDs) in each EoIP. One EoIP tunnel is configured between the guest anchor controller and each internal controller that supports access points with guest client associations. Q. What controllers can be used to support guest access in the unsecured network area? A. The guest tunnel anchor function, which includes EoIP tunnel termination, Web authentication, and access control of guest clients, is supported in these Cisco Wireless LAN Controller platforms with Version 4.0 and later software images: (1) Cisco 4400 Series Wireless LAN Controller (either the 4402 or the 4404), (2) Cisco Catalyst 6500 Series Wireless Services Module (WiSM), and (3) Cisco Catalyst 3750G Integrated Wireless LAN Controller. Q. Why choose Cisco infrastructure-integration of comprehensive wireless security features? A. Cisco reduces capital costs while streamlining security operations. The Cisco Secure Wireless solution delivers (1) Proactive threat and intrusion detection capabilities that don't just detect wireless attacks but prevent them, (2) Comprehensive protection to safeguard your company's confidential data and communications, (3) Simplified user management with a single user identity and policy, which also protects against unauthorized access, and (4) Collaboration with wired security systems that enables a superset of wireless security functionality and protection. Q. How can your business extend communications with mobile solutions? A. Mobilize your workforce by extending communications to create a unified workspace so that employees can do their jobs from everywhere. To meet the needs of the mobile workforce, Cisco offers a comprehensive set of mobile solutions that are integral to Cisco Unified Communications products. Mobile solutions offer a variety of intelligent endpoints, including wireless IP phones, mobile phones, and smartphones. People communicate the way they want to, whether they are in the office, on the road, or at home. Cisco Unified Communications enable all phones and devices to operate from a secure, enterprise-managed platform . With mobile solutions you can combine the convenience, flexibility, and reach of mobile communications with the benefits of Cisco Unified Communications. The combination of unified communications and mobility greatly enhances employee effectiveness by: (1) Reducing complexity, (2) Supporting the use of a single business number and voice mailbox, (3) Allowing communications to shift more easily between voice calls, voicemail, e-mail, and instant messaging, and (4) Improving the ability to make the right connection, or find the appropriate information the first time. Q. Why choose Cisco Wireless Security for your business? A. With Cisco, you get all the components required for secure deployment and operation of a wireless network as part of the Cisco Unified Wireless Network infrastructure. Cisco wireless controllers, access points, and wireless management system, deliver comprehensive protection against wireless attacks with infrastructure-integrated threat protection, advanced visibility into the RF environment, and wired network security collaboration. Q. Why Migrate to a Cisco Unified Wireless Network? A. The Cisco Unified Wireless Network reduces overall operational expenses by simplifying network deployment, operations, and management. Features and benefits include: (1) Lower total cost of ownership, (2) Enterprise-class security with a built-in intrusion prevention system (IPS) and intrusion detection system (IDS), (3) Centralized network management of campus, branch office, and remote locations, (4) Real-time radio-frequency (RF) monitoring and management that is self-configuring, self-optimizing, and self-healing, and (5) Integrated mobility services for security, voice, guest access, and location services. |
