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

7 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 n

8 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

9 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

10 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

11 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

12 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

13 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

14 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

15 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

16 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

17 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).

20 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

21 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

22 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

23 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.

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

35 Cisco Strategic Focus Besides Mobility Controllers (4400, 2100) – Switches (3750, 6500) and ISR (Integrated Services Router) series can be upgraded to have wireless controller ability Fat APs can be upgraded to Thin APs Unified 11n AP (Aironet 1250)

36 Cisco Technical Basics Control packets between AP & Controller are sent thru LWAPP Tunnel Wireless traffics MUST be forwarded to Controller for decryption Controllers share client information by EoIP tunnel in order to support roaming EoIP (Ethernet over IP) Control Packets Wireless Traffic Encrypt Decrypt Encrypt

37 Cisco Issues Controller/LWAPP architecture is not scalable, especially when under intensive throughput or remote AP applications To resolve this problem, Cisco has REAP (Remote Edge AP) and H-REAP (Hybrid REAP) REAP or H-REAP support Local-Switched. Wireless traffics do not go back to the Controller. But… REAP & H-REAP are only supported by few selected AP models Extra license fee and fw upgrade are needed for REAP & H-REAP Only ONE VLAN is supported for wireless traffic on REAP! H-REAP does not support WPA2 fast Roaming! H-REAP does not support client load balancing! H-REAP does not support Station Isolation (WLAN partition)! 4402 and 4404 Controllers are not future-proofing With 4G and 8G switching separately. Sufficient for 50 and a/b/g APs. The switching power will not satisfy 11n AP’s needs! New n AP does not support REAP or H-REAP!

38 Cisco Issues D-Link’s solution is scalable, flexible, and future-proofing AP supports Adaptable Wireless: Local-switched (VLAN forwarding mode) and Central-switched (L3 Tunneling mode) without extra license fee and fw upgrade With 24 GE ports, 24G switching power, and Adaptable Wireless support, suitable for future 11n AP upgrade Cisco’s Unified AP is actually fw upgrade to standalone AP with extra charge D-Link’s Unified AP provides maximized flexibility Unified AP is supported in one single fw, and can operate between standalone and managed mode without fw change and extra fee, providing maximized flexibility.

40 Aruba Strategic Focus Follow-me Security Identity-based security Centralized security & voice add-on modules Voice services Policy enforcement firewall Wireless intrusion protection VPN server External services interface xSec All with expensive extra fees Large supported AP number, good for very large deployment (>500 APs)

41 All the wireless traffic must be tunneled back before heading for the destination Marketing focus Central traffic management Truly Secure – Encrypted traffic from Client to Controller L2 or L3 Network packets on GRE Tunnel Aruba Issues Technical Basics

42 Aruba Issues Central-switched architecture is not scalable Remote AP is introduced to avoid this problem, but… Only few selected models (60, 61, 70AP) support Remote AP Extra fee, fw upgrade, no flexibility Aruba Controllers are not future-proofing 11n sales pitch: (http://www.arubanetworks.com/pdf/technology/whitepapers/wp_AWO.pdf) Even with 11n AP, same amount of users will generate same amount of wireless traffic If possible, add a slave Controller at the edge Suggested to deploy 11n AP only at the location that needs more bandwidth Low throughput ports (MC-2400: 24FE + 2SFP) Current Mobility Controllers definitely will not handle 11n traffic! Does not protect customer’s investment

43 Aruba Issues Add-on security modules are selling points. But do customers need them? Is encrypted traffic all the way from client to the controller truly secure? Wireless – Encrypted by wireless protocols Wired - Most of the enterprises do not encrypt wired traffic. When they need it, they have VPN gears Cisco discontinues selling VPN module on Mobility Controllers due to low demand All modules with extra cost Good for large enterprises, but large enterprises usually already had other best-of-breed solutions! No Unified AP D-Link provides scalable, future-proofing, and cost effective solution!
