1. Business Solution Seminar 2008 D-Link Unified Switch October – November 2008

2. Centralized WLAN Solution Becomes Main Stream Revenue from sales of WLAN switches and controllers increased 92% year on year, totalling $572 million (equivalent to 43% of the WLAN market revenue). The business market will continue the gradual shift from the traditional stand-alone WLAN architecture to the newer, centralized one (WLAN switches and controllers managing coordinated access points) in 2007 Shipments of coordinated access points are forecast to account for 71 percent of the total enterprise-class access point shipments by 2010 Source: Infonetics Research, 2007 Source: Gartner, 2006 Market Update Business WLAN

4. Flexible Deployment Overlay Solution – Wireless Controller Deployment Deploy deeper into existing network infrastructure to protect current investment in network infrastructure

5. Flexible Deployment Unified Solution – Converged Edge Deployment Deploy at the network edge for greatest scalability, and with all the benefits of Unified Switching Full GbE speed for next generation 802.11n

6. Flexible Deployment Adaptable Wireless Wireless traffic can be local-switched at the AP or Central- switched at the Unified Switch depending on users’ needs No need to purchase additional license or upgrade firmware Internet Server Farm Local-Switched (Non-Tunnel Mode) Better performance Central-Switched (Tunnel Mode) Better centralized security control Unified Switch

7. Security can be pre-set and management of AP can be centralized 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. Unified Switch will automatically detect all APs attached to the switch When an AP is removed or added, switch automatically configures new AP with same configuration of replaced unit Unified Switch AP-1 AP-2 AP-3 1> AP-3 appear and attached to a Unified Switch port 2> New AP detected!!! APs detected on the network AP-1 AP-2 AP-3 3> Configured AP with the pre-set profile configuration Pre-set Configuration and Centralized Management

8. Central Policy Control Security setting/configuration can be saved even when the AP is powered off. Unified Switch L3-switch L2-switch Access points attached to the network Pre-set profile configuration Content of pre-set profile configuration packet: RADIUS server settings Security settings Radio configuration SSIDs, VLAN & Tunnel setting QoS configuration Pre-set profile configuration Pre-set Configuration and Centralized Management

9. Automatic channel adjustment Unified Switch automatically adjusts channels in the controlled Access Points in an event such as a new AP being added or being removed Unified Switch can be programmed to automatically readjust channels periodically at certain time or upon a certain interval. Unified Switch Channel 36 Channel 40 Channel 44 Channel 48 New AP attached to the network Scan RF area for occupied channel… Select non-interfering channel Channel 44 Appear rogue AP which using channel 44 Experience signal interference, Change channel Channel 52 RF Management

10. Automatic power adjustment Automatically adjust the RF signal to broadcast far enough to reach wireless clients, but not so far that it interferes with RF signals broadcast by other APs When a Managed AP is powered down, the power of its neighboring AP(s) managed by the same switch is immediately increased by 20% (Fail-safe feature). Wireless coverage area Another AP appear on the network Power adjusted to prevent interference The AP is powered down Power increased RF Management & Self-Healing Wireless Network

11. Unified Switch performs load utilization across the switch-managed access points on per radio basis based on AP’s utilization rate. The APs report bandwidth utilization to the Unified Switch regularly If the bandwidth utilization reaches a configured threshold then the new client associations are rejected. The new client will be forced to connect to an overlapped neighbor AP with lower utilization. Unified Switch Default bandwidth utilization: 60% AP-1 AP-2 user4 Utilization rate increased Reach utilization threshold!!! Utilization rate for AP-2: 10% Attempt to connect AP-1 User4 rejected Force to connect to Ap-2 User4 connect to AP-2 Load Utilization

12. Fast Roaming Ideal for VoIP Application Fast L2/L3 Roaming One DWS-3000 switch can support fast roaming across up to 48 APs. This fast roaming can be supported with in a subnet (Layer 2) or across subnet boundaries (Layer 3). Unified Switch AP-1 AP-3 AP-2 Subnet A Subnet B L2 Roaming L3 Roaming

13. Fast Roaming Inter-Switch Roaming 4 Peer Switches in the same Roaming group Not only can D-Link’s DWS-3000 support fast roaming between APs being managed by a particular switch, but can support up to 4 peer Unified Switches in a roaming group. Support up to 192 APs Since each switch can support up to 48 APs, this means up to 192 APs can be supported in a mobility group or domain. L2 or L3 Inter-Switch Roaming

14. Fast Roaming Pre-Shared Keys Fast Roaming No relocating IP Re-auth time is tiny Dynamic Keys (WPA2 Enterprise) Fast Roaming No relocating IP Re-auth time is tiny – the dynamic key - PMK (Pairwise Master Key) can be cached in Switch and forwarded to APs in the same roaming group Management of thousands of users is possible Radius Server PSK PMK 802.1x Auth

15. Enhanced Security Enforcement Rogue AP Management Any AP scanned but not in the switch’s database will be listed as a rogue AP. The administrator can get better control of the environment through knowing rogue APs’ information (MAC, SSID, Channel, etc). Complete Security Features Wireless Managed AP MAC list Wireless Client MAC list WEP (Static/Dynamic) WPA Enterprise/Personal WPA2 Enterprise/Personal Captive Portal Wired ACL 802.1X DoS Control Broadcast Storm Control Port Security Radius / TACACS+

18. D-Link Unified Access System includes a set of comprehensive management functions for managing and monitoring the WLAN by using one of the three methods provided Web-based management interface Command-Line Interface (CLI) The command-line interface (CLI) is a text-based way to manage and monitor the system. CLI can be accessed by using a direct serial connection or by using a remote logical connection with Telnet or SSH. Simple Network Management Protocol (SNMP) The D-Link Unified Switch uses both standard public MIBs for standard functionality as well as a number of additional private MIBs for additional functionality supported by the switch. Comprehensive Network Management

19. Shows summary information about managed, failed, and rogue access points the switch has discovered or detected. The font color for the AP listing indicates that the AP is one of the following types: Green—Managed AP Red—Failed AP Gray—Rogue AP Amber—Peer Managed AP Monitoring All Access Points

20. Provides a variety of information about each AP that the switch manages. Status tab provides configuration and association information about managed APs and their neighbors. Statistics tab displays information about the number of packets and bytes transmitted and received on different interfaces. Monitoring All Access Points

21. Shows a variety of information about the wireless clients that are associated with the APs the switch manages. Monitoring Associated Clients Authenticated Client info can be logged by SNMP Trap or Syslog.

22. View and manage wireless clients that are connected to the WLAN through an ad hoc network. Monitoring and Managing Ad-Hoc Clients
