8 Configuring Guest Access 168Installation and User Guide: Airgo Access Point Figure 119 provides a sample illustration of how clients are treated when guest access is implemented without VLANs. Secure clients are authenticated using WPA-PSK, while guests are authenticated through the landing page (internal page is shown). Both types of users gain access to the same network resources; however, only the secure user traffic is encrypted. Figure 119:Guest Access Without VLANs Guest access with VLANs This option, in which VLANs are used to differentiate between corporate traffic and guest user traffic, is ideal for businesses that want to provide guest access to visitors. When guest users log in, they are automatically assigned to the guest VLAN and are prevented from accessing the main corporate network. To use VLANs for guest access, the AP must be connected to a VLAN-aware switch, and the switch must be configured to support the designated VLANs. The VLAN configuration of the upstream network should make available only those network resources set aside for guest use. This often means prohibiting guest stations from accessing anything other than the corporate open subnet or the Internet. For open guest access, the Open access security option must be configured. This precludes the use of WEP Security Mode on APs that provide guest access, but does permit use of WPA Security Mode for non-guests only. NOTE: If both secured and open access are enabled (mixed-mode of operation) then some third party clients may not be able to access the network using WPA-PSK. All clients will be able to connect to the network using the open authentication correctly. ID Password Network Corp Guest Access Secure User Traffic Is Encrypted Guest Traffic is Not Encrypted Secure Client Authenticates with Pre-shared Key A0064 Guest Internal Landing Page Installation and User Guide: Airgo Access Point169 VLANs and security privileges are assigned to users by way of service profiles defined for user groups and bound to the network SSID. It is required that the VLAN configuration include DHCP and DNS services. Internal Landing Page The internal landing page is a configurable option within the Airgo AP. The guest password for the AP can be set using the Guest Access panel, or an automatically generated password can be configured through the User Management panel in NM Portal. If the automatically generated guest password is used, then the authentication process for the internal landing page also checks the password entered by the guest user against the RADIUS authentication service provided in the security portal. If either password is acceptable, the guest user is authenticated and receives the privileges specified in the guest service profile. Internal landing pages are compatible with the VLAN and non-VLAN options. Figure 120 shows how Acme Works configured guest access with an internal guest landing page. In this example, the company has two VLANs: Corporate and Guest. Corporate and guest users belong to the Enterprise and Guest user groups, respectively, with appropriate service profiles assigned and bound to the SSID. Corporate users are authenticated by way of the enterprise RADIUS server, while guest users are authenticated by way of an internal landing page configured in the Airgo AP. After they are authenticated, guest users are place in the Guest VLAN. I NOTE: If guest access is configured on a VLAN other than VLAN 1, the DCHP server on the AP cannot be used to provide IP address service for the guest VLAN. Use an external DHCP server. 8 Configuring Guest Access 170Installation and User Guide: Airgo Access Point Figure 120: Guest Access - Internal Landing Page RADIUS Server A0045D Corp VLAN Corp-VLAN VLAN Switch Guest VLAN Guest-VLAN Corp Guest Access Guest ID Password External Landing Page Installation and User Guide: Airgo Access Point171 External Landing Page An external landing web page can be set up through a corporate web server. The URL for the landing page must use an IP address rather than a domain name. Regardless of the authentication process selected for the external page, it is necessary to forward authentication results to the AP upon completion of successful or unsuccessful guest authentication. 1 External landing pages are compatible with the VLAN and non-VLAN options. Figure 121 shows a network VLAN configuration with an external guest landing page. The external landing page is made accessible over the Internet through an external web server. As in the previous example, authenticated guest users are given access to the guest VLAN. Figure 121: Guest Access - External Landing Page 1 An example external landing page is shipped with the Airgo AP. RADIUS Server A0045B CorporateVLAN CorporateVLAN VLAN Switch GuestVLAN GuestVLAN Corporate Guest Web Authentication Password Authentication Results Passed Back to AP 8 Configuring Guest Access 172Installation and User Guide: Airgo Access Point Open Subnet In an optional open subnet arrangement, shown in Figure 122, unauthenticated guest users are permitted limited access to an open enterprise subnet specified in the Airgo AP. The enterprise open subnet must be part of the Guest VLAN. Extended access requires authentication through an internal or external landing page. Figure 122: Guest Access - Open Subnet Guest Access Persistence If a guest user is temporarily disconnected from the Airgo AP due to loss of association, it may not be necessary for the user to reauthenticate if the client reassociates to the same AP within one minute. This is particularly beneficial when using a virtual private network (VPN) with guest access, wherein the user signs on as a guest and then launches a VPN session to a remote VPN server. Since the VPN session is tunneled over the guest session, a temporary loss of connectivity does not require tearing down the VPN session. If loss of association extends beyond one minute, it is necessary for the guest user to reauthenticate. In…

10 Maintaining the Access Point 258Installation and User Guide: Airgo Access Point Installation and User Guide: Airgo Access Point259 A Using the Command Line Interface This appendix explains how to access and interact with the command line interface (CLI). For detailed information on specific commands, see the CLI Reference Manual. Using the Command Line Interface To connect to the AP for command line interface access using Secure Shell (SSH), do the following: 1Launch your SSH client application. 2Type ssh admin@<AP IP address>, using the AP IP address assigned to the Access Point (or 192.168.1.254 by default) and press Return. When connected, a screen opens similar to the one shown in Figure 188. Figure 188: Access Point Serial Console Login Screen 3Enter your login ID and press Return. When prompted next, enter your password. The factory default for administrator access is username: admin. The factory default password is shipped with the AP on a paper insert. Use the password from the insert to log in. NOTE: SSH Communications provides an SSH client, http://www.ssh.com. A Using the Command Line Interface 260Installation and User Guide: Airgo Access Point 4To see the list of available commands, type a question mark (?). For a list of hot keys (short cuts for console functions, press Ctrl-H. There are two important modes in console access, one is show mode and the other is config mode. In show mode, examine the AP’s configuration settings and status. Use config mode to change values. To go into either mode from the main command> prompt, type either show or config. Toggle between show and config modes by pressing Ctrl-P. Leave a mode and return to the top level command prompt by typing exit. 5To log out and close your connection to the command line interface, type logout at any prompt. Using the Console Port for CLI Access To connect to the AP for command line interface (CLI) access using the built-in console port, do the following: 1Connect your computer to the AP console port using a serial DCE cable (this is typically a 9- pin-to-9-pin cable with the transmit and receive lines crossed over — a null modem cable). A USB-to-Serial adapter may be required if your computer lacks a 9-pin serial port. 2Launch your terminal emulation application. On PCs running Microsoft Windows operating systems, the Microsoft-provided application HyperTerminal will work fine. (This is accessed usually through Programs > Accessories > Communications > HyperTerminal. The remainder of this procedure assumes the use of HyperTerminal. Modify the procedures accordingly if using another application.) 3Create a terminal connection profile if one does not already exist. Enter a descriptive name and select any icon from the list provided. Click OK when done. If there is a working HyperTerminal connection profile, select that shortcut instead to launch the connection, and skip to step 7. 4The Connect To screen displays. The important element there is to use the Connect using: box, and select the serial port to which the AP is connected. Click OK when done. 5Use the following port settings: • Bits per second: 115200 • Data bits: 8 • Parity: None • Stop bits: 1 • Flow control: None 6Click OK when done. When connected, a screen opens similar to the one shown in Figure 188. 7If the console login screen in the HyperTerminal does not open, press Return once or twice. If you still see nothing or garbage characters appear, check the cable connection and the terminal connection parameters. 8Enter your login ID and press Return. When prompted next, enter your password. (The AP defaults are login: admin and password: password, and login: opr and password: opr for operator (read-only) access.)
