3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 1Chapter 1: IntroductionThe 3e-528 Wireless Video Server system (WVS) is a key component of any Critical Infrastructure Protection System implementation. 3e-528 WVS is a combination of products and services which enable the design, provisioning, implementation, operation, and maintenance of an inte-grated network to provide advanced video surveillance. 3e-528 delivers the architectures along with the supporting systems & services necessary for Wide Area / Local Area Network deployment of wireless and wired IP video networks across municipalities, campuses, transportation and other critical infrastructure locations. 3e-528 ensures heightened security through real-time video capture and transmission of high-resolution digi-tal imagery. The system expands your security presence to numerous key locations and events to improve safety by reducing threats. It allows you to focus valuable personal on areas of critical concern where and when they are needed Capabilities3e-528 WVS solutions track activity around selected areas and aid in securing critical infrastructure. They enhance security; improve safety; detect threats and lower crime rates. Typical critical infrastructure targets include:• Municipal Complexes• Transportation centers – Airports, Railroads, Maritime Ports• Bridges / tunnels• Arenas & Convention Centers• Public Events• Power Grids• Water systems / facilitiesFunctionalityUp to four cameras are easily connected to the 3e-528 Wireless Video Server - a mixed network of IEEE 802.11b/g wireless and wired Ethernet connections. The cameras can be controlled by a centralized operations staff that remotely controls each camera’s Pan/Tilt/Zoom (PTZ) features, views live footage, records every camera for a specied period, reviews recorded footage, and outputs selected segments to digital or analog
3e-528 Wireless Video Server Chapter 1: Introduction2 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 3media. Because the 3e-528 WVS system has dual mode wireless capability (802.11g and 802.11b), local 802.11b 11Mbps wireless hotspots can be en-abled around the video server locations. These hotspots serve to provide high speed mobile data access to police, emergency management person-nel, and other municipal/government rst responders.The wireless portion of the 3e-528 Wireless Video Server system meets DoD security requirements with advanced data encryption (AES / 3DES) and uses crypto modules that are FIPS 140-2 Validated™ for sensitive data communications use. The 3e-528 system also supports use of exist-ing Ethernet resources wherever possible to avoid additional build out costs. Because of its wireless bridging capabilities, the 3e-528 WVS system is easily expandable to support future growth without the material, time and costs associated with traditional wired links.Video System FeaturesThe 3e-528 WVS system supports most outdoor IP video surveillance cameras. It has analog to digital video conversion capabilities and mul-tiple wireless or wired Ethernet connections. • Network Connectivity— 802.11b/g 54Mbs Wireless Bridging/Repeating of video to Operations Centers— Provides serial server for sensor interface over the wireless or wired IP network connections— Provision for 802.11b 11Mbs Wireless LAN Hotspot in addi-tion to wired Ethernet— Transport minimum video resolution of 640x480 with 4CIF quality— Capability to convert and send up to 30 video frames per second— Able to control a minimum 25x OPTICAL zoom on appro-priate cameras— Wireless camera signals are securely transmitted with FIPS 140-2 Validated AES encryption— An optimum mix of wireless and wired resources — Supports all cameras operating at a minimum of 7.5 Frames Per Second— Termination of the video accomplished at one or more Op-erations Centers• Housing— Ruggedized outdoor housing for 3e-528 system components— 4 port serial server connections for sensor interface includ-ing camera pan/tilt/zoom control — 4 hardened video connections (BNC) • Management— Enables wireless digital transport and subsequent storage at Operations Center— Provision for optional dynamic key server for increased security
3e-528 Wireless Video Server Chapter 1: Introduction2 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 3— Wireless connectivity for viewing 4 live camera feeds— Simultaneous use of all functions— Access user restrictions— Supports central operation/access of all cameras— Non-proprietary output format for admissibility in court (JPEG, M-JPEG, NTSC Video, etc.)— Camera control via 1 serial interfaceIf encryption is desired for the WLAN, you can employ different encryption depending on the mode you are in. If you are using FIPS 140-2 mode (highly secure) you can set encryption for None, Static AES, Static 3DES, or Dynamic Key Exchange. If you are not using the 3e-528 in FIPS 140-2 mode, you can select None, Static AES, Static 3DES, Static WEP, or WPA. WPA uses TKIP or AES-CCMP so you can employ legacy cli-ent WEP cards and still secure the wireless band. If it is desired that the wireless video server employs state-of-the-art AES or 3DES encryption for wireless access, wireless clients must have the 3e-010F Crypto Client software installed. (The 3e-010F Crypto Client software is sold with the 3e-110 long range PC card or sold separately for use with other compat-ible PC cards.) The 3e-528 has an Ethernet WAN interface (WAN port) for commu-nication to the wired LAN backbone, three Ethernet LAN local interfaces (CONFIG ports) for purposes of initial setup and conguration, one AP antenna for 802.11 b wireless clients, and three bridging antennas for com-municating on the 802.11b/g radio.The 3e-528 is wall-mountable.It has the following features:• Ethernet WAN port• "CONFIG" Ethernet LAN ports (for conguration only)• Wireless (802.11b) AP with operating range of 2000+ feet• Wireless (802.11b/g) bridge• AES, 3DES, WEP encryption or WPA with TKIP, depending on setup• HTTPS/TLS secure Web• DHCP client• Video Server port• Bandwidth control• Adjustable Radio Power• MAC address ltering• Load Balancing• Rogue AP Detection
3e-528 Wireless Video Server Chapter 1: Introduction4 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 5The following cryptographic modules have been implemented in the 3e-528 .• AES (128/192/256 bit)• 3DES (192 bit)• WEP• WPA• 802.1x/EAP-TLS for authentication Wireless BasicsWireless networking uses electromagnetic radio frequency waves to transmit and receive data. Communication occurs by establishing radio links between the wireless access point and devices congured to be part of the WLAN.The 3e-528 incorporates WiFi standard and FIPS 140-2 security for wireless communication. 802.11bThe IEEE 802.11b standard, developed by the Wireless Ethernet Compatibility Alliance (WECA) and ratied by IEEE, establishes a stable standard for compatibility. A user with an 802.11b product can use any brand of access point with any other brand of client hardware that is built to the 802.11b standard for basic interconnection. 802.11b devices provide 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps depending on signal strength) in the 2.4 GHz band. For wireless devices to communicate with the 3e-528 , they must meet the following conditions:• The wireless device and wireless access point must have been congured to recognize each other using the SSID (a unique ID assigned in setup so that the wireless device is seen to be part of the network by the 3e-528 );• Encryption and authentication capabilities and types en-abled must conform; and• If MAC ltering is used, the 3e-528 must be congured to allow the wireless device’s MAC address to associate (com-municate) with the 3e-528 wireless interface.802.11gBecause 802.11g is backwards-compatible with 802.11b, it is a popular component in LAN construction. 802.11g broadens 802.11b’s data rates to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division multiplexing) technology.
3e-528 Wireless Video Server Chapter 1: Introduction4 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 5Network CongurationThe 3e-528 is a wireless video server and access point with bridging capability: The wireless bridging function supports a number of bridging congurations. We discuss the most popular settings in this manual.• Video Server and Access Point plus:• Wireless bridging with choice of: - Point-to-point setup - Point-to-multipoint setup - Repeater setupAccess Point CongurationsIP addresses for wireless devices are typically assigned by the wired network’s DHCP server. The wired network’s DHCP server assigns ad-dresses dynamically, and the AP virtually connects wireless users to the wired network. All wireless devices connected to the AP are congured on the same subnetwork as the wired network interface and can be ac-cessed by devices on the wired network. Both wireless clients and devices connected to the wired network can access the video server. In order to access the video interface, the IP address of the video card needs to be congured manually to be within the same network. Refer to the Video Conguration section to learn more about the video conguration (Chap-ter 4).
3e-528 Wireless Video Server Chapter 1: Introduction6 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 7Possible AP Topologies1. An access point can be used as a stand-alone AP without any connection to a wired network. In this conguration, it simply provides a stand-alone wireless network for a group of wireless devices with or without a video connection in the AP (3e-528). 2. There can be multiple APs with video access (3e-528) connected to an existing Ethernet network to bridge between the wired and wireless environments. Each AP can operate independently of the other APs on the LAN. Multiple APs can coexist as separate individual networks at the same site with a different network ID (SSID).    
3e-528 Wireless Video Server Chapter 1: Introduction6 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 73. The last and most prevalent use is multiple APs connected to a wired network and operating off that network’s DHCP server to provide a wider coverage area for wireless devices, enabling the devices to “roam” freely about the entire site. The APs have to use the same SSID. This is the topology of choice today.  BridgingThe 3e-528 can also function as a bridge. There are a number of bridg-ing congurations supported, including the following popular congura-tions:• Point-to-point bridging of 2 Ethernet Links;• Point-to-multipoint bridging of several Ethernet links;• Repeater mode (wireless client to wireless bridge.)Default CongurationThe 3e-528's default conguration is an Access Point/Bridge with FIPS 140-2 submode enabled. The video card and the three bridges need to be congured before being able to access the system.Data Encryption and SecurityThe 3e-528 Wireless Video Server includes advanced wireless security features. You have a choice of no security, Static WEP, WPA, AES/3DES, depending on your mode of operation. Static WEP gives you a choice of 64-bit or 128-bit encryption. WPA includes the option of using a WPA pre-shared key or, for the enterprise that has a Radius Server installed, con-guration to use the Radius Server for key management with either TKIP or AES-CCMP. Bridging encryption is established between 3e-528’s and includes use of AES-ECB or 3DES encryption (approved by the National Institute of Standards and Technology (NIST) for U.S. Government and DoD agencies).
3e-528 Wireless Video Server Chapter 1: Introduction8 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 9SSID The Service Set ID (SSID) is a string used to dene a common roam-ing domain among multiple wireless access points. Different SSIDs on access points can enable overlapping wireless networks. The SSID can act as a basic password without which the client cannot connect to the network. However, this is easily overridden by allowing the wireless AP to broadcast the SSID, which means any client can discover the AP. SSID broadcasting can be disabled in the 3e-528 setup menus.WEPWEP is an older encryption standard that has been superseded by stronger encryption options. If the 3e-528 is congured with WEP encryp-tion, it is compatible with any 802.11b PC card congured for WEP.WPA with TKIP/ AES-CCMPWPA, an interim standard developed by the WiFi Alliance, combines several technologies. It includes the use of the 802.1x standard and the Extensible Authentication Protocol (EAP). In addition, it uses, for encryp-tion, the Temporal Key Integrity Protocol (TKIP) and WEP 128-bit encryp-tion keys. Finally, a message integrity check (MIC) is used to prevent an attacker from capturing and altering or forging data packets. In addition, it can employ a form of AES called AES-CCMP. The 3e-528 allows the user to congure.WPA is a subset of the 802.11i standard and is expected to maintain forward compatibility. AES and 3DESThe Advanced Encryption Standard (AES) was selected by National Institute of Standards and Technology (NIST) in October 2000 as an up-grade from the previous DES standard. AES uses a 128-bit block cipher algorithm and encryption technique for protecting computerized infor-mation. It has the ability to use even larger 192-bit and 256-bit keys, if desired. 3DES is also incorporated on the 3e-528. 3DES is modeled on the older DES standard but encrypts data three times over. Triple-DES uses more CPU resources than AES because of the triple encryption. If you intend to use AES or 3DES, you must purchase the 3eTI ad-vanced Crypto Client software (3e-010F) for each client that will be in-cluded in the WLAN. We sell this software with the 3e-110 PC Card.The 3e-528 uses AES-CCMP in WPA mode and AES-ECB (or 3DES) for FIPS 140-2 mode and for bridging.
3e-528 Wireless Video Server Chapter 1: Introduction8 29000142-001 A3e-528 Wireless Video Server Chapter 1: Introduction29000142-001 A 9MAC Address FilteringThe MAC address, short for Media Access Control address, is a hard-ware address that uniquely identies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub-layers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network media. Consequently, each type of network media requires a unique MAC address. Authentication is the process of proving a client identity. The 3e-528 access points, if set up to use MAC address ltering, detect an attempt to connect by a client and compare the client’s MAC address to those on a predened MAC address lter list. Only client addresses found on he list are allowed to associate. MAC addresses are pre-assigned by the manu-facturer for each wireless card.DHCP ServerThe DHCP function is accessible only from the local LAN port to be used for initial conguration. Operator Authentication and ManagementAuthentication mechanisms are used to authenticate an operator ac-cessing the device and to verify that the operator is authorized to assume the requested role and perform services within that role.Access to the management screens for the 3e-528 requires knowledge of the assigned operator ID and Password. The Factory defaults are:• ID: CryptoOfcer• Password: CryptoFIPSThe Crypto Ofcer initially installs and congures the 3e-528 after which the password should be changed from the default password. The ID and Password are case sensitive.Management After initial setup, maintenance of the system and programming of security functions are performed by personnel trained in the procedure using the embedded web-based management screens. The next chapter covers the basic procedure for setting up the hard-ware.

3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 19Chapter 3: Access Point CongurationIntroductionThe 3e-528 features three bridging ports interconnected to each other inter-nally. The rst bridging port, accessible from the CONFIG 1 port, can also act as an access point. This unit incorporates two separate 802.11 wireless cards, one 802.11b card that acts as a WLAN, and one dual 802.11b/g card for use in wire-less bridging. The 3e-528 wireless video server can be further congured for use in FIPS 140-2 secure mode. In this example of conguration, we have chosen to present all the screens in the FIPS 140-2 mode. There are a few differences in non-FIPS mode which are described in the Navigation chart on page 9. Preliminary Conguration StepsFor preliminary installation the 3e-528 network administrator may need the following information:• IP address Note: To set up one 3e-528 you will need ve IP addresses. One for the accesspoint port (the rst bridging port uses the same IP address), three for the other bridging ports, one for the video server card, and one for the serial server card for PTZ (pan/tilt/zoom).• Subnet Mask• Default IP addresses of the 3e-528 – 192.168.254.254 for the AP and rst bridge – 192.168.254.20 for the video server – 192.168.254.30 for the serial card• DNS IP address• SSID – an ID number/letter string that you want to use in the congu-ration process to identify all members of the wireless LAN. • The MAC addresses of all the wireless cards that will be used to access the 3e-528 network of access points (if MAC address ltering is to be enabled)• The appropriate encryption key for wireless connection.
3e-528 Wireless Video Server Chapter 3: Access Point Conguration20 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 21Initial Setup using the “CONFIG 1” PortPlug setup cable into the LAN (CONFIG 1) port of the 3e-528 (see page 13) and the other end to an Ethernet port on your laptop. This LAN port in the 3e-528 connects you to the Access Point’s internal DHCP server which will dynami-cally assign an IP address to your laptop so you can access the device for congu-ration. In order to connect properly to the 3e-528 on the LAN port, the TCP/IP parameters on your laptop must be set to “obtain IP address automatically.” (If you are unfamiliar with this procedure, use the following instructions for deter-mining or changing your TCP/IP settings.)In Windows 98/Me click Start à Settings à Control Panel. Find and double click the Network icon. In the Network window, highlight the TCP/IP protocol for your LAN and click the Properties button. Make sure that the radio button for Obtain an IP address automatically is checked.In Windows 2000/XP, follow the path Start à Settings à Network and Dialup Connections à Local Area Connection and select the Properties button. In the Properties window, highlight the TCP/IP protocol and click properties. Make sure that the radio button for Obtain an IP address auto-matically is checked.Once the DHCP server has recognized your laptop and has assigned a dynamic IP address, you will need to nd that IP address. Again, the procedure is similar for Windows 95/98/Me machines and slightly different for Windows 2000/XP machines.In Windows 98/Me, click Start, then Run and type winipcfg in the run instruction box. Then click OK. You will see the IP address of your laptop in the resulting window, along with the “default gateway” IP address. Verify that the IP address shown is 192.168.15.xIn Windows 2000/XP, click Start, then Run and type cmd in the run instruction box. Then click OK. This will bring up a window. In this win-dow, type ipcong /all |more. This will list information assigned to your laptop, including the IP address assigned. Verify that the IP address shown is 192.168.15.x

This screen lists the rmware version number for your 3e-528 and allows you to set the Host Name and Domain Name as well as establish system date and time. (Host and Domain Names are both set at the factory for “default” but can optionally be assigned a unique name for each.) When you are satised with your changes, click Apply.Go next to the System Conguration—WAN screen.

This directs you to the System Conguration – WAN screen.If not using DHCP to get an IP address, input the static IP information that the access point requires in order to be managed from the wired LAN. This will be the IP address, Subnet Mask, Default Gateway, and, where needed, DNS 1 and 2. Click Apply to accept changes.

It also allows changing the default numbers for the LAN Subnet Mask and the link speed. The Local LAN port provides local access for conguration. It is not advisable to change the private LAN address while doing the initial setup as you are connected to that LAN. Operating ModeThis screen allows you to set the operating mode to either FIPS enabled or disabled. You can also set the device to use IPv6. Note that if you change modes, all previously entered information will be reset to factory settings.Submodes There are two options under Submodes: • FIPS 140-2 Mode• Use IPv6 ModeIf you can select the Use IPv6 Mode, the AP will be congured to support IPv6 addresses on the WAN and LAN ports. In IPv6 mode, the AP can be man-aged and pass trafc using IPv6 addresses. Since IPv6 is relatively new in the
3e-528 Wireless Video Server Chapter 3: Access Point Conguration24 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 25industry, some networking functions that cannot support IPv6 are disabled such as DHCP server and WPA-802.1x.When in IPv6 mode, the AP can be accessed from the management port using IP address 192.168.15.1. This is the default IP address and it can not be changed. The WAN port can not be accessed using IPv4 addresses.If "Use IPv6 mode" is selected as a submode then you will need to enter an IPv6 address under System Conguration—WAN and LAN screens.

This nomenclature has to be set on the access point and each wireless device in order for them to communicate.
3e-528 Wireless Video Server Chapter 3: Access Point Conguration26 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 27You can assign a channel number to the AP (if necessary) and modify the Tx Pwr Mode. The Channel Number is a means of assigning frequencies to a series of access points, when many are used in the same WLAN, to minimize interference. There are 11 channel numbers that may be assigned. If you assign channel num-ber 1 to the rst in a series, then channel 6, then channel 11, and then continue with 1, 6, 11, you will have the optimum frequency spread to decrease “noise.”If you are using the 3e-528 as both an AP and bridge, the channel number set for the AP board and the channel number set for the bridge should be sufciently different to avoid interference.If you click on the button Select the optimal channel, a popup screen will display the choices. It will select the optimal channel for you. You can also set up the optimal channel at boot up. Tx Pwr Mode and Fixed Pwr Level: The Tx Power Mode defaults to Auto, giving the largest range of radio transmission available under normal conditions. As an option, the AP's broadcast range can be limited by setting the Tx Power Mode to Fixed and choosing from 1-8 for Fixed Pwr Level (1 being the shortest distance.) Finally, if you want to prevent any radio frequency transmission, set Tx Pwr Mode to Off.There are a number of advanced options included on this screen as described in the following chart:Advanced OptionsBeacon Interval Range 20-1000 The time interval in milliseconds in which the 802.11 beacon is transmitted by the AP. RTS Threshold Range 1-2346 The number of bytes used for the RTS/CTS handshake boundary. When a packet size is greater than the RTS threshold, the RTS/CTS handshaking is performed.DTIM Range 1-255 The number of beacon intervals that broadcast and multicast trafc is buffered for a client in power save mode.Basic Rates Basic Rates for 802.11b1 and 2 Mbps1, 2, 5.5 and 11 MbpsThe basic rates used and reported by the AP. The highest rate specied is the rate that the AP uses when transmitting broadcast/multicast and management frames. Preamble Short/Long PreambleSpecies whether frames are transmitted with the Short or Long PreambleBroadcast SSID Enabled/disabledWhen disabled, the AP hides the SSID in outgoing beacon frames and stations cannot obtain the SSID through passive scanning.Also, when it is disabled, the AP doesn’t send probe responses to probe requests with unspecied SSIDs.

AES uses a 128-bit block cipher algorithm and encryption technique for protecting information. With the ability to use even larger 192-bit and 256-bit keys, if desired, it offers higher security against brute-force attack than the old 56-bit DES keys. Static 3DES KeyTo use 3DES, enter a 192-bit key as 48 hexidecimal digit (0-9, a-f, or A-F).
3e-528 Wireless Video Server Chapter 3: Access Point Conguration30 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 31Dynamic Key ExchangeDynamic key management requires the installation of the 3e-030 Security Server software which resides on a self-contained workstation connected to the 3e-528 over the WAN port. The Security Server software conguration includes: obtaining a root certicate from a Certicate Authority (CA) like Microsoft; obtaining user certicates based on the CA which will be used by the clients; and conguring the 3e Technologies International's Security Server software with the appropriate root certicate. The Security Server software application is discussed in a separate manual.If you have installed the Security Server software, Dynamic Key Manage-ment is the preferred security setup. Get the IP Address and password of the Security Server and the Key type. Key type will be either 3DES (192-bit), or AES (128-bit, 192-bit or 256-bit). Thereafter, the Security Server handles authentication dynamically.Once you have selected the options you will use, click Apply.If you have the 3e-528 congured in non-FIPS mode, the security screens will look a bit different.

A screen will appear, asking if you really want to operate in Bypass mode. If you answer Yes, no encryption will be applied.Static WEP Encryption (non-FIPS)If you choose to use WEP encryption, you can also select whether it will be Open System or Shared Key authentication. For greater security, set authen-tication type to “shared key.” WEP Data encryption can be set to 64-bit or 128-bit encryption.WEP (Wired Equivalent Privacy) Encryption is a security protocol for wire-less local area networks (WLANs) dened in the 802.11b standard. WEP was originally designed to provide the same level of security for wireless LANs as
3e-528 Wireless Video Server Chapter 3: Access Point Conguration32 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 33that of a wired LAN but has come under attack for its defaults and is not now state of the art. WEP relies on the use of identical static keys deployed on client stations and access points. But the use of WEP encryption provides some mea-sure of security. Utilities exist for scanning for networks and logging all the networks it runs into—including the real SSIDs, the access point’s MAC address, the best sig-nal-to-noise ratio encountered, and the time the user crossed into the network’s space. These utilities can be used to determine whether your network is unse-cured. Note that, if WEP is enabled, that same WEP key must also be set on each wireless device that is to become part of the wireless network, and, if "shared key" is accepted, then each wireless device must also be coded for "shared key". To use WEP encryption, identify the level of encryption, the Default WEP key and designate the WEP keys as shown on the screen.WPA (non-FIPS)Wi-Fi Protected Access or WPA was designed to enable use of wireless legacy systems employing WEP while improving security. WPA uses improved data encryption through the temporal key integrity protocol (TKIP) which scrambles keys using a hashing algorithm and, by adding an integrity-checking feature, en-sures that the keys haven’t been tampered with. In addition, user authentication is enabled using the extensible authentication protocol (EAP). If you wish to use WPA on the 3e-528, enable either WPA Pre-shared Key Set-tings or WPA 802.1x Settings.If you are a SOHO user, selecting pre-shared key means that you don’t have the expense of installing a Radius Server. Simply input up to 63 character / numeric / hexadecimals in the Passphrase eld. If your clients use WPA-TKIP, select TKIP as encryption type. If your clients use WPA-AES, select AES-CCMP. Re-keying time is the frequency in which new encryption keys are generated and distributed to the client. The more frequent re-keying, the better the security. For highest security, select the lowest re-keying interval.

If you enable MAC Address ltering, you should also set the toggle for Filter Type. This works as follows:• If Filtering is enabled and Filter Type is Allow Access, only those devices equipped with the authorized MAC addresses will be able to communicate with the access point. In this case, input the MAC address-es of all the PC cards that will be authorized to access this access point. The MAC address is engraved or written on the PC (PCMCIA) Card. • If Filtering is enabled and Filter Type is Disallow Access, those devices with a MAC address which has been entered in the MAC Ad-dress listing will NOT be able to communicate with the access point. In this case, navigate to the report: Wireless Clients and copy the MAC address of any Wireless Client that you want to exclude from communi-cation with the access point and input those MAC Addresses to the MAC Address list.

If you enable rogue AP detection, also enter the MAC Ad-dress of each AP in the network that you want the AP being congured to accept as a trusted AP. (You may add up to 20 APs.) Enter an email address for notica-tion of any rogue or non-trusted APs. (The MAC Address for the 3e-528 is located on the System Conguration—General screen. You can also select the follow-ing lter options.The Adjacent AP list, under Monitoring/Reports on the navigation menu, will detail any marauding APs.
3e-528 Wireless Video Server Chapter 3: Access Point Conguration36 29000142-001 A3e-528 Wireless Video Server Chapter 3: Access Point Conguration29000142-001 A 37AdvancedThe Advanced screen allows you to enable or disable load balancing and to control bandwidth.Load balancing is enabled by default. The load balancing feature balances the wireless clients between APs. If two APs with similar settings are in a conference room, depending on the location of the APs, all wireless clients could potentially associate with the same AP, leaving the other AP unused. Load balancing at-tempts to evenly distribute the wireless clients on both APs.If enabled, the Bandwidth Control function works by limiting the maximum bandwidth a single client is allowed to have. For example, if the total bandwidth for the AP/WLAN is 4 Mbps and bandwidth control is set to 500 kbps or 0.5 Mbps, the network can only serve a maximum of 0.5 mbps per client. Even if only one client is on the network, a maximum of 0.5 Mbps will be allowed. If, on the other hand, the BW Control is set to a higher number (say 3 Mbps), a single client can take up to 3 Mbps of bandwidth when it requires while the other cli-ents will share the remaining bandwidth. The decision as to who gets the 3 Mbps and who gets the remainder depends on the requirement and when the require-ment is acknowledged. This function can be disabled and the available band-width will be portioned out as required. If total bandwidth required exceeds the available bandwidth, the client last in line will get only the remaining bandwidth available.Once you have made any changes, click Apply to save.

The default factory setting for the DHCP server function is enabled. You can disable the DHCP server function, if you wish. You can also set the range of addresses to be assigned. The Lease period (after which the dynamic address can be reassigned) can also be varied. It is not recommended that you disable this feature.The DHCP server function, accessible only from the LAN port, is used for initial conguration of the management functions.Subnet RoamingThe 3e-528 supports subnet roaming with 3eTI's subnet roaming coordina-tor server installed. Subnet roaming occurs when a user roams to an access point that is connected to a different subnet than its home subnet. If subnet roaming is supported by the wireless infrastructure, the client is able to continue its network connectivity without having to change its IP address. Therefore, to the mobile de-vice, roaming is transparent and it will continue to function as if it is in its home subnet.
