Chapter 8 Authentication Authentication Methods in Dell Instant Authentication is a process of identifying a user by having them to provide a valid username and password. Clients can also be authenticated based on their MAC addresses. The following authentication methods are supported in Dell Instant: 802.1X Authentication Captive Portal MAC Authentication 802.1X Authentication 802.1X is a method for authenticating the identity of a user before providing network access to the user.
Controller (the client certificate must be signed by a known CA) before the user name is checked on the authentication server. EAP-TTLS (MSCHAPv2)— The Extensible Authentication Protocol-Tunneled Transport Layer Security (EAP-TTLS) method uses server-side certificates to set up authentication between clients and servers. However, the actual authentication is performed using passwords. EAP-PEAP (MSCHAPv2)— Protected Extensible Authentication Protocol (PEAP) is an 802.
If you are using the IAP’s internal database for user authentication, you need to add the names and passwords of the users to be authenticated. If you are using an LDAP server for user authentication, you need to configure the LDAP server on the Virtual Controller, and configure user IDs and passwords. If you are using a RADIUS server for user authentication, you need to configure the RADIUS server on the Virtual Controller.
Admin-DN— Enter a Distinguished Name for the admin user who has read/search privileges across all the entries in the LDAP database. The user may not have write privileges but will be able to search the database, and read attributes of the other users in the database. Admin password— Enter a admin password. Base-DN— Enter a Distinguished Name of the node which contains the entire user database. Filter— Indicates the filter that should be applied to search for the user in the LDAP database.
Enabling Instant RADIUS To enable Instant RADIUS, perform the following steps: 1. Click the Settings at the top right corner of the Instant UI. 2. Select Enabled from the Dynamic RADIUS Proxy drop-down list. When enabled, the Virtual Controller network will use the IP Address of the Virtual Controller for communication with external RADIUS servers.

Chapter 9 Encryption Encryption Types Supported in Dell Instant Encryption is the process of converting data into an undecipherable format or code when it is transmitted on a network. Encryption prevents unauthorized use of the data. The following encryption types are supported in Dell Instant: WEP Though WEP is an authentication method, it is also an encryption algorithm where all users typically share the same key.
Understanding WPA and WPA2 The Wi-Fi Alliance created the Wi-Fi Protected Access (WPA) and WPA2 certifications to describe the 802.11i standard. The standard was written to replace WEP, which was found to have numerous security flaws. It was taking longer than expected to complete the standard, so WPA was created based on a draft of 802.11i, which allowed people to move forward quickly to create more secure WLANs. WPA2 encompasses the full implementation of the 802.11i standard.

Chapter 22 Alert Types and Management Alert Types Alerts are generated when a user encounters problems while accessing or connecting to the Wi-Fi network. These alerts enable you to troubleshoot the problems. The alerts that are generated on Dell Instant can be categorized as follows: 802.11 related association and authentication failure alerts. 802.1X related mode and key mismatch, server, and client time-out failure alerts. IP address related failure - Static IP address or DHCP related alerts.
Table 31 Alerts List (Continued) Type Code 100308 Description Details Corrective Actions RADIUS server connection failure The IAP cannot authenticate this client using 802.1X because the RADIUS server did not respond to the authentication request. If the IAP is using the internal RADIUS server, recommend checking the related configuration as well as the installed certificate and passphrase.
Chapter 23 Policy Enforcement Firewall Dell’s Policy Enforcement Firewall (PEF) module for Dell Instant provides identity-based controls to enforce application-layer security, prioritization, traffic forwarding, and network performance policies for wired and wireless networks. The PEF window displays the external/internal authentication servers, currently defined roles for all the networks, blacklisted clients and to enable or disable the protocols for ALG.
Users for Internal Server This section displays the currently defined users for the internal authentication server. Figure 154 Users for Internal Server To add a user, perform the following steps: 1. Enter the username in the Username text box. 2. Enter the password in the Password text box and reconfirm. 3. Select appropriate network type from the Type drop-down list. 4. Click Add and click OK. The users are listed in the Users list. See “User Database” on page 203 for more information.
Access Rules— This table lists the permissions for each Role. See Chapter 10, “Role Derivation” for more information. Figure 155 Roles Client Blacklisting The client blacklisting denies connectivity to the blacklisted clients. When a client is blacklisted in a Dell IAP, the client is not allowed to associate with the IAP in the network. If a client is connected to the network when it is blacklisted, a deauthentication message will be send to force the client to disconnect.
Types of Client Blacklisting The following types of client blacklisting can be generated in an Instant: Manual Blacklisting Dynamic Blacklisting Authentication Failure Blacklisting Session Firewall Based Blacklisting Manual Blacklisting Manual blacklisting is the simplest way to add a client to the blacklist. In manual blacklisting, the MAC address of the client has to be known to the user. These clients would be added into a permanent blacklist.
Session Firewall Based Blacklisting In session firewall based blacklisting, an ACL rule is used to enable the option for automation blacklisting. when the ACL rule is hit, it would send out blacklist information and the client would be blacklisted. To set the blacklist duration, perform the following steps: 1. Select the PEF link and then select Blacklisting tab.
4. Click OK. NOTE: When the protocols for ALG are Disabled the changes do not take effect until the existing user sessions expire. Reboot the IAP and the client, or wait for few minutes to ensure the changes take effect. Firewall-based Logging Instant firewall now supports firewall based logging function. The firewall logs on the Instant APs are generated as syslog messages. 196 | Policy Enforcement Firewall Dell PowerConnect W-Series Instant Access Point 6.1.3.1-3.0.0.
Chapter 24 VPN Configuration The IAP supports termination of a VPN tunnel on the Dell PowerConnect W controller. VPN features are ideal for: enterprises with many branches that do not have a dedicated VPN connection to the HQ. branch offices that require multiple APs. individuals working from home, connecting to the VPN.
6. Select Enabled from the Preemption drop-down list to switch back to the primary host when and if it becomes available again. This step is optional. 7. Enter the Hold time which indicates the duration of the controller that will remain on the backup controller. 8. Click Next to continue. Routing Profile Configuration Instant can terminate VPN connections on Dell Mobility Controllers. The Routing profile defines the corporate subnets which need to be tunneled through the IPSec tunnel.
L2 Switching Mode— In this mode, Instant supports the following two types to support L2 switching mode of connection to corporate: Distributed L2— In this mode, the VC assigns an IP address from a configured subnet and forwards traffic to both corporate and non-corporate destinations. The VC adds the VLAN configured in this subnet to the controller VLAN multicast table enabling the L2 subnet to act as an extension of the VLAN on the controller.
Figure 163 NAT DHCP Configuration 2. Click OK to apply these changes. Distributed L2 DHCP Configuration In Distributed L2 mode, the Virtual Controller acts as the DHCP Server but the default gateway is in the data center. Traffic is bridged into VPN tunnel. 1. Click New in the DHCP Server window and select Distributed, L2 to configure the following parameters for Distributed L2 mode DHCP pool: Name— Name of the subnet (must be unique). Type— Indicates the type of DHCP server.
Figure 164 Distributed L2 DHCP Configuration Distributed L3 DHCP Configuration In Distributed L3 mode, the Virtual Controller acts as both DHCP Server and default gateway. Traffic is routed into the VPN tunnel. 1. Click New in the DHCP Server window and select Distributed, L3 to configure the following parameters for Distributed L3 mode DHCP pool: Name — Name of the subnet (must be unique). Type— Indicates the type of DHCP server.
