16. L2/L3 AP Auto-Discovery and Centralized Management Auto-discovery feature allows unified switch and AP to discover each other automatically in L2/L3 network L2 auto-discovery – Switch discovers AP L3 auto-discovery – Switch discovers AP L3 auto-discovery – AP discovers switch Auto-discovery with DHCP option 43 Centralized policy control The profile configuration is applied to a managed AP on the event such as when an AP initially transitions to managed mode, or when AP is reset. Customers hence can enjoy the convenience of one-time configuration Page is Animated L2 or L3 Network Profile dispatch Firmware dispatch

17. Switch Clustering Peer Switches can form a Cluster Group Up to 4 DWS-3160 could be a Cluster Group All wireless configuration & management can be done from one switch One Master Switch gathers all statistics and status from peer switches, APs and clients in the group Provides single point of management Similar to D-Link Single IP Management (SIM) Peer Switches Admin Master Switch Wireless Management & Configuration

18. N+1/ N+N Switch Redundancy N+1 Unified Switch Redundancy One extra switch works only as backup Allow each switch manages its maximum number of APs Unified Switch 2 Unified Switch 1 L2 or L3 Network Primary: Unified Switch 1 Secondary: Unified Switch BKP Primary: Unified Switch 2 Secondary: Unified Switch BKP N+N Unified Switch Redundancy Each switch backup its peer switches In order to backup peer switches, the switch needs to reserve some space for peer switch managed APs. Therefore, it cannot manage its maximum number of APs

19. Fast L2/L3 Roaming Ideal for VoIP application Fast roaming can be supported within a subnet (Layer 2) or across subnet boundaries (Layer 3) without changing IP address of client Intra-switch roaming Fast roaming between APs which are managed by the same switch Inter-switch roaming Fast Roaming between switches in a roaming group Up to 4 DWS-3160 can form a Roaming group DWS-3160 I DWS-3160 II Clustering Intra-Switch L2 Roaming Associate with AP-A1 AP-A1 AP-A2 Handover from AP-A1 to AP-A2 Associate with AP-A2 AP-B1 AP-C1 Associate with AP-B1 Intra-Switch L3 Roaming Inter-Switch L3 Roaming Associate with AP-C1

20. Fast Roaming Enhancement: AP-AP Tunnel AP-AP Tunnel mode is used to support L3 roaming without forwarding any traffic to the Unified Switch  The APs will create tunnel and forward traffic with each other When clients roam to another AP which is not in the same network subnet, the traffic from roamed clients is tunneled to the originally associated AP of the client Roamed client remains on the same VLAN and has the same IP address Benefit Reduce network resources because traffic is forwarded locally Reduce Unified Switch loading Page is Animated 192.168.1.0172.17.3.010.10.10.0 AP-AP Tunnel DWS-3160 L3 Switch

21. 2. Rogue AP Or Radio interference Channel 48 Auto Channel Adjustment Channel 24 Channel 48 Channel 36 New AP Channel 54 3. Changes to Channel 18 1. When inserting new AP, the AP scans the RF area for occupied channels and selects a channel from the available non-interfering, or clear channels. Auto select proper channel and assign to managed APs In a clustering group, adjust the channels for new event in the system, such as an AP be added, the unified switches readjust channels by schedule (ex. at certain time, upon a certain interval) Change channels by experiencing the influences from environment

22. Auto RF Management Auto Power Adjustment In a clustering group, automatically adjust the power according to the strength changes of RF signals broadcasting by other APs, the unified switches readjust power by schedule (ex. upon a certain interval) RF Self-Healing When a Managed AP is powered down, the power of its neighboring AP(s) managed by the same switch is immediately increased by 20% The power level will readjust again every pre-configured interval by sensing neighboring AP power status Clustering Power 90% Power 90% Power 50% Power 50% Power 50% Power 90% Power 60% Channel Plan Period Power Adjustment Auto Power Adjustment AP Fail RF Self-Healing Auto Power Adjustment Power 90% Power 30% Power 70%

23. Advanced RF Feature: Radio Protection Advanced “Radio Protection” design to guarantee that 802.11 transmissions do not cause interference with legacy stations or applications It is great feature to sustain 11n client throughput on mixed wireless clients environment (11n, 11g and 11b wireless clients work together) Without Radio Protection, the 11n wireless clients will run at 11g or 11b wireless speed in mixed environment. Customers won’t need to replace all legacy wireless clients to get the benefit on 11n transmission (High throughput, High reliability) Run at 802.11 b/g Transmission rate 802.11 b/g client 802.11n client Run at 802.11 b/g Transmission rate 802.11n client Run at 802.11 b/g Transmission rate Run at 802.11 n Transmission rate 802.11n client Run at 802.11 n Transmission rate With Radio Protection Enabled

24. AP Traffic Load Balancing Balance traffic load of each Managed APs Based on the percentage of bandwidth utilization Based on the Max. Wireless Clients Force a new client associating to an overlapped neighbor AP which has lower unitization while the nearest one exceed the threshold Periodically update APs utilization reports Utilization Threshold: 60% Request connection to AP-A AP-B AP Traffic Load Balancing Reject association from AP-A AP-A checks its utilization AP-A reaches the utilization threshold value Force the association to AP-B AP-A

25. Centralized User Access Control SSID Based Access Control Define Different VLANs and SSIDs for different user group (ex. Sales, RD…) With ACL configuration on VLAN, administrator can define particular access policy for specific user group The users belong to different groups need to connect with different SSIDs to get proper access right after authentication successfully Identity Based Access Control Support Dynamic VLAN Assignment with WPA/WPA2-Enterprise, MAC and 802.1X authentication In a SSID, the clients could be assigned to different VLANs that are preconfigured in the external RADIUS server With ACL configuration on VLAN, administrator can define particular access policy for specific user/ user group V3V3 V1V1 V2V2 Single SSID User 2 ( ex. Guest)  Internet Access Only User 1 (ex. RD)  Server, Internet Access RADIUS Server User1 go to V2 User2 go to V3 AP-A

26. Wireless Intrusion Detection System (WIDS) AP detection and classification Periodically scan and detect the AP per device or per clustered group Four classes for AP: Managed, Standalone, Unknown, and Rogue Wireless client detection and classification Monitor disassociated, pre-authenticated, and authenticated wireless clients Three classes for authenticated wireless client: Authenticated, Black-listed, Rogue RF Scanning Hacker ? Infect MANAGED STANDALONE UNKNOWN ROGUE AP Classification ? AUTHENTICATED BLACKLISTED ROUGE Client Classification B B -Fake managed AP -Fake managed SSID -AP using illegal channel -AP using invalid channel -Incorrect security config -Invalid SSID -Unexpected WDS device -Etc… -Not in client database -Probe attack -Flooding network -Too many failed auth -Authenticated with Unknown AP -Etc…

27. Wireless Intrusion Prevention System (WIPS) AP & Wireless Client Threat Mitigation Protect wireless clients away from threats by sending fake de-authentication messages to de-associate the connection with rogue APs Inform to every managed AP the list of BSSIDs and channels on which rogue APs are operating Lock down the location of rogue AP via WLAN Visualization Tool for security adjustment Send de-authentication message De-association with rogue AP Detect rogue AP Visualized Alive Site Map Lock down location MANAGEDSTANDALONEUNKNOWNROGUEAP Classification?
