16 Installing the Extricom WLAN System Determining the Location of the Extricom Access Points Before installing the switch and access points, plan the placement of the APs. Before permanently mounting the APs, it is recommended to test the network (using a laptop client) to identify potential coverage holes. If such a problem exists, relocate an AP or add additional APs to resolve the coverage hole. The APs should be placed in a stable, secure location, such as on top of a closet or bookshelf, or mounted on a wall. The switch should be placed near the distribution point of the LAN line. This is usually in the communications closet of your enterprise. The Extricom EXSW800/1200/2400/8000 Switch The Extricom EXSW800 switch has 10 connectors and 4 LED types on the front panel (refer to Figure 10). The Extricom EXSW-1200 switch has 15 connectors and 4 LED types on the front panel (refer to Figure 11).

30 Configuring the Extricom WLAN System Table 7. WLAN Configuration Parameters Field Description Channel Options Enable Check this box if you want to enable the radio. WLAN Mode Select the WLAN mode. Possible options are:  802.11a  802.11b  802.11g for pure mode  802.11b/g for mixed mode  Since the Extricom solution can support two simultaneous channels in the same frequency band, selecting the WLAN mode enables the Extricom solution to offer same band capability. This means that both radios can be set to: 1. 802.11a & 802.11a 2. 802.11b & 802.11b 3. 802.11b & 802.11g 4. 802.11g & 802.11g 5. 802.11b/g & 802.11b/g And any other combination. Channel Select the channel. The options available are based on the country and WLAN mode. Maximum Retries Select the number of times to try to resend a packet if the transmission of the packet fails. Allow Rate Adaptation Check this box if you want to enable rate adaptation.  All enabled rates participate in the rate adaptation..
The Extricom WLAN System User Guide 31 Field Description Rate Configuration For each of the data rates listed, select whether the rate is Basic, Optional, or Disabled. When configuring the data rates, you should consider the data rate capabilities of the wireless devices in your enterprise.  Basic – The Basic data rates are usually the data rates that the vast majority of your wireless devices can support. Only wireless devices that support all the Basic data rates will be connected to the WLAN system. Therefore, it is recommended that you configure a minimal number of Basic data rates that the vast majority or all your wireless devices can support. When working in Mixed Mode, there should be at least one Basic data rate from the 802.11b rates.  Optional – If you configure a data rate as Optional, the network will provide that data rate to wireless devices that can support it.  Disabled – Disabled data rates are not available to wireless devices.  Since the Extricom WLAN system allows for dense deployment of APs, it is recommended, where applicable, to disable low data rates. Not doing so could possibly lead to an “edge user” effect, in which a client reduces aggregate network throughput by moving to the edge of the coverage area. Short Preamble: This option becomes available only when selecting 802.11b as the WLAN mode. In this case, mark the checkbox to allow a short preamble. Setup SSIDs Assigned SSIDs Displays the list of SSIDs assigned to the channel. Remove from Channel To remove an SSID from the channel, select an SSID and check the Remove from Channel option. The SSID is removed from the Assigned SSIDs list, and appears on the Unassigned SSIDs list after clicking Update.  In the Extricom WLAN system, a single channel can support up to 16 different SSIDs (system limit of 32).

Add to Channel To add an unassigned SSID to the channel, select an SSID from the Other SSIDs list and check the Add to Channel option. The selected SSID is removed from the Other SSIDs list and added to the Assigned SSIDs list after clicking Update. New SSID To create a new SSID and assign it to the selected channel, enter a unique SSID name and check the Create and Assign option. The new SSID is added to the Assigned SSIDs list after clicking Update.  The character Space may be used in SSID name. Create and Assign Check to assign the new SSID. The new SSID is added to the Assigned SSIDs list after clicking Update. All SSIDs Displays a list of all SSIDs configured for the switch. (assigned/unassigned) Delete Permanently To delete an SSID from the switch, select an SSID from the All SSIDs list and check the Delete Permanently option. The SSID is removed from any list on which it appears after clicking Update. 5. Click Update to save the configuration.  The new configuration only takes affect after rebooting or reconfiguring the Extricom Switch (refer to Rebooting the Extricom Switch on page 56). 6. To configure WLAN parameters for another radio, click the tab for that radio, configure the WLAN parameters, and click Update to save the configuration. 7. To configure SSID and security settings, click Edit SSID & Security Setting. Refer to Configuring SSIDs on page 32, and Configuring Security Definitions on page 37.  To configure SSID and security settings, you can also click SSID & Security in the navigation tree. Configuring SSIDs An SSID (Service Set Identifier) is the name of the network. Wireless devices must connect to a specific SSID which determines the pre-defined set of privileges, settings, and limitations (such as security definitions, access privileges, VLAN assignments, etc.) of the network. Each channel can support multiple SSIDs, thus creating “virtual” networks on the same channel.
The Extricom WLAN System User Guide 33 The following is the data structure used by the Extricom system:  Each radio is assigned one channel.  Each channel can support up to 16 different SSIDs.  Each SSID can be associated with a VLAN tag.  The same SSID name cannot be repeated for different channels. Table 8 shows this data structure with an example of possible channel, SSID and VLAN tag assignments. Table 8.

SSID Options Allow Default SSID If this option is enabled, a wireless device will be allowed to connect even without requesting a specific SSID (i.e., “default” or “any” SSID) to the Extricom WLAN. If this option is disabled, then a wireless device needs to connect to a specific SSID in the Extricom WLAN. Display SSID in Beacon This option provides an additional (though limited) level of security. The AP sends out a beacon with information about the network. If this option is enabled, the SSID appears in the beacon. If disabled, the SSID does not appear in the beacon. Allow Store & Forward If this option is enabled, two wireless devices connected to the Extricom WLAN with the same SSID can communicate and transfer data to each other. Traffic between wireless devices will not be forwarded to the LAN switch. If this option is disabled, all traffic goes through the LAN switch. . This could be used by IT managers to apply security settings or various policies in the LAN network.  Disabling Allow Store & Forward disables the Allow Inter-Ess Forward option.
36 Configuring the Extricom WLAN System Field Description Allow Inter-Ess Forward If this option is enabled, two wireless devices connected to the Extricom WLAN with different SSIDs will be able to communicate with each other without going through a router. Traffic between wireless devices will not be forwarded to the LAN switch.  This option must be enabled on both SSIDs. In order for wireless devices, associated to different SSIDs, to be able to communicate with each other, the SSIDs must be defined on the same VLAN (or no VLAN at all). If this option is disabled, all traffic goes through the LAN switch. This could be used by IT managers to apply security settings or various policies in the LAN network. Enable Multicast This option, when enabled, provides support of multicast and broadcast packets for the selected SSID. Multicast and/or broadcast packets shall be transmitted from all APs. ARP Caching This option, when enabled, provides an immediate response to ARP requests directed towards WLAN stations associated with the selected SSID. The Switch answers on behalf of the WLAN stations. MAC ACL This option, when enabled, allows a user to add a MAC access list to the specific SSID. Only clients with MAC address included in this list are allowed to access the network. 802.1d Support Enables support of the 802.11d standard .The purpose of this standard is to provide regulation domains for each country in a predefined list. The regulation domains and Country information are provided as part of Beacons & Probe response. VLAN Enter a VLAN tag to assign to the SSID. Assigning a VLAN to an SSID enables you to control a wireless devices’ privileges through the existing wired network definitions. Disassociation Timeout Enter the amount of time (in seconds) a wireless device can remain inactive (no data sent to or from the wireless device) before automatically disconnecting from the network.
The Extricom WLAN System User Guide 37 Field Description DTIM Period The period of time after which broadcast and multicast packets are transmitted to mobile clients in the Active Power Management mode. Select the DTIM period for the selected SSID. This is relevant for clients that want to utilize the power management capability. The possible values are 1-5. The default is 3.  A high DTIM value may cause these clients to lose connection with the network.  The remaining parameters in the SSID & Security page are described in Configuring Security Definitions on page 37). 3. Click Update to save the configuration.  The new configuration only takes affect after rebooting the switch (refer to Rebooting the Extricom Switch on page 56). Configuring Security Definitions In the SSID & Security page Encryption & Authentication section (refer to Figure 22), the following security definitions can be configured:  Type of encryption.  Type of authentication.  With some configurations, you can use encryption without authentication. However, for a higher level of security, it is recommended to use both encryption and authentication.  Extricom system eases the configuration of the SSID security parameters by providing a list of available combinations of Encryption and Authentication protocols Security definitions are configured for each SSID individually. To configure the security definitions: 1. Click SSID & Security in the navigation tree. The SSID & Security page appears (refer to Figure 22). 2. Select the SSID from the Choose SSID dropdown list for which you want to configure the security definitions.
38 Configuring the Extricom WLAN System 3. Configure the security definitions for the selected SSID. Refer to Table 10 for a description of the Security parameters. Table 10. Security Definition Parameters Field Description Encryption & Authentication Choose method Define the method of encryption and authentication. A combination of encryption and authentication methods may be selected from the options detailed in the drop-down list. Encryption cipher There are three types of encryption ciphers available:  WEP64 – Wired Equivalent Privacy (802.11 encryption protocol). This is a very basic encryption level. (AKA WEP40)  WEP128 – This encryption is similar to WEP64, but the WEP keys are longer. (AKA WEP104)  TKIP – Temporal Key Integrity Protocol. This is a more secure and more advanced method of encryption as a part of the WPA standard.  AES (CCMP) – Advanced Encryption Standard.(Cipher Block Chaining Message Authentication Code Protocol) is currently the most advanced and secured method of WiFi encryption and is part of 802.11i (WPA2) standard. Authentication method Authentication is used to identify if a wireless device is authorized to connect to the WLAN, and verifies the wireless device’s identity. Authentication methods (such as specific EAP methods available in the WPA/WPA2 (RADIUS) option) also verify that the association process is secured. Authentication utilizing WPA/WPA2 (RADIUS) can also support encryption key changes. The following methods are available:  802.1x – if the cipher is WEP or WEP104  WPA/WPA2-PSK or WPA/WPA2 (RADIUS) – if the cipher is TKIP or AES  Supported protocols: EAP, TLS, TTLS, PEAP, LEAP and MD5  When choosing the encryption cipher and authentication methods, one should take into account wireless devices’ capabilities.  The Extricom system supports “WPA2 Mixed Mode”. This mode permits the coexistence of WPA and WPA2 clients on the same SSID. WPA2 mixed mode allows “Old” WLAN clients with “New” WLAN clients on the same SSID during transition period.
The Extricom WLAN System User Guide 39 Field Description Any security combination (Encryption and Authentication) can be selected by the user as a combination of the list and the check boxes. WEP Keys The WEP Keys area is only enabled if the cipher selected in the Choose Method field is WEP or WEP104. In the WEP Keys area, you define the WEP Key that is used for encrypting or decrypting. You can define all four WEP keys. For each key you define, select the input format (ASCII or HEX) and enter the key according to the following table: Cipher ASCII HEX WEP64 (or WEP64+802.1x) 5 characters 10 digits WEP128 (or WEP128+802.1x) 13 characters 26 digits Transmission Key Select the WEP64/WEP128 key to be used for transmitting the data from the AP. WPA The WPA area is only enabled if the cipher selected in the Choose Method field is WPA/WPA2 TKIP/AES. WPA-PSK If WPA/WPA2 with Pre-Shared key authentication is used, the WPA-PSK field is enabled. In this case, select one of the following input formats, and enter the corresponding key listed:  For ASCII, enter 8-63 characters.  For HEX, enter 64 digits. WPA/RADIUS Re-key Interval Enter the amount of time (in seconds) that elapses before the Group Key is changed. RADIUS Define the RADIUS servers parameters if:  The cipher is WEP64/WEP128, and the 802.1x authentication method is selected.  The cipher is TKIP/AES, and the WPA/WPA2 (RADIUS) authentication method is selected. Server Address Enter the address of the RADIUS server.  Use Server # 1 if only one server is used. Use consecutive servers if several servers are used. Server Port Enter the RADIUS server port. Server Password Enter the RADIUS server password. Server Timeout Enter the time which the Extricom switch waits for the RADIUS server response.
40 Configuring the Extricom WLAN System Encryption and Authentication methods. The “Choose Method” drop down list in “Encryption & Authentication” displays the following items for user selection:  None  WEP64 (Open)  WEP128 (Open)  WEP64 & 802.1x Authentication  WEP128 & 802.1x Authentication  WPA/WPA2 TKIP/AES & Pre Shared Key Authentication  WPA/WPA2 TKIP/AES & 802.1x Authentication When the “WPA2 Only” is checked, only Clients with WPA2 support are allowed access to the WLAN. When the “AES Only” is checked, only Clients with AES support are allowed access to the WLAN. Cisco LEAP protocol (not CMIC & CKIP) is supported under “WEPxxx & 802.1x Authentication”. Multiple RADIUS and RADIUS redundancy RADIUS is a common authentication protocol utilized by the 802.1x security standard (often used in wireless networks). Although RADIUS was not initially intended to be a wireless security authentication method, it improves the WEP encryption key standard, in conjunction with other security methods such as EAP-PEAP. In an enterprise environment, several RADIUS servers may be used for backup and also for serving different geographical locations. Up to four different RADIUS servers can be defined for each SSID. RADIUS redundancy is based on the assumption that the user database is identical in all RADIUS servers and that users are listed in all servers with the same credentials. Switchover from one RADIUS server to another takes place after consecutive failures of the server. The order of priorities is 1 to 4. 4. Click Update to save the configuration.  The new configuration only takes affect after rebooting or reconfiguring the switch (refer to Rebooting the Extricom Switch on page 56).

The Extricom WLAN System User Guide 47 IDS Tab Intrusion detection system (IDS): Malicious WLAN clients can cause a denial of service by flooding the WLAN network. Denial of services is identified through attack signatures or other factors, most of which are well-known. The IDS tab allows the user to enable this mechanism, set thresholds for identifying an attack and choose type of attack to be detected. The IDS mechanism detects 802.11 duration attack and 802.11 management messages flooding attacks. Upon attack detection, the system sends a Trap message notifying the event and when applicable provides attacker details (i.e. MAC address). Network administrator can use this information to take action and block malicious users. Figure 28: IDS Configuration

The Extricom WLAN System User Guide 49 Centralized Configuration Settings Centralized Configuration allows managing a group of identical Extricom switches (slaves) from one single master switch. The user should decide which switch will act as master. Extricom Switches have a built-in mechanism to discover the presence of other switches. In addition, the user is given the ability to manually configure the entries in the table of switches. Configuration changes on the master switch are propagated to the slave switches via a secured mechanism. For this authentication scheme to work, the slave switches need to obtain a copy of the master's public key prior to the centralized configuration. This is done in the initial phase of the switch’s configuration by first retrieving the master's public key and then uploading it to the designated slave switches. Figure 29. Central Configuration Page
50 Configuring the Extricom WLAN System To configure Centralized Configuration parameters: Initial Setup 1. Configure the LAN settings on the Master switch 2. Generate an SSH key pair on the Master switch. This is done by clicking on the Update button next to the generate New SSH Keys. 3. Retrieve the SSH public key from the Master switch and save it in a file on your PC. 4. Manually configure each of the Slave switches’ LAN settings, and continue by uploading the previously saved master's public key on every Slave you wish to manage. This allows the Slave switch to be configured only by the Master switch which generated the public key. Figure 30. Central Configuration Page Slave Switch Configuration 1. On the Master switch, open the Centralized Configuration web page and click on the Update button in the Switches Table section. This will retrieve and generate the Slave switches’ information and all the relevant dialog boxes will be populated with data. 2.
