The xStack DWS-3227 is an integrated wired and wireless switching solution capable of providing powerful wireless security, easy deployment, the ability to detect rogue access points, and centralized management for all compatible WLAN components. The xStack DWS-3227 switch provides secure, seamless roaming between access points ensuring clear, uninterrupted data and voice communication throughout your wireless network infrastructure. The DWS-3227 comes standard with a 10 client AP license upgradeable to 25. And is capable of supporting 25 APs per switch /stack with up to 1500 WLAN clients.
Centralized Management The xStack DWS-3227 is capable of centralized management of compatible wireless access points. No longer will each individual access point need to be configured independently. Now your entire wireless network can be managed through a single interface. The xStack DWS-3227 includes support for automatic discovery and configuration of APs with real-time monitoring, providing visibility into utilization and performance of WLAN users and devices.
Security The D-Link xStack DWS-3227 provides Enhanced Wireless Security Features to ensure your data is protected from hackers. Support for WEP, WPA and WPA2 Encryption guarantees the privacy of your network data. Rogue AP detection and containment ensure only the APs you install are able to function on your network. AP detection allows identification of APs into “known” and “rogue” classifications. The switch uses the APs to continuously scan radio channels in an attempt to identify transmissions of unauthorized WLAN nodes facilitating notification, tracing, and or jamming of the rogue signals.
Seamless Roaming When a user roams between APs connected to different broadcast domains, the user's IP address is no longer valid after the move to the new AP. This means the user's device (laptop, PDA, VoIP phone) will need to change its IP address thus breaking the active session. With “always connected” devices such as VoIP phones and PDAs this can create a huge problem. The need for a solution to provide seamless roaming between APs on different subnets becomes essential to maintaining active sessions and VoIP calls.
The D-Link DWS-3227 addresses this problem by bringing AP configurations and support directly into the switch itself. This allows the user to move between access points (within a single stack of up to 32 DWS-3227 switches) with seamless mobility. To the user's PDA or VoIP phone, the move appears as if it were between APs on a single broadcast domain. This means the user's device will retain its VLAN membership and IP address guaranteeing uninterrupted communication.
Advanced Wired Functionality** The xStack DWS-3227 supports a variety of features designed to provide high-availability, redundancy and uptime. The xStack DWS-3227 supports “ Shortest-Path” switching, for improved network efficiency, an optional Redundant Power Supply, and support for enterprise class networking features such as cross stack 802.3ad Link Aggregation, DNA redundant fail-over stacking, 802.1d, 802.1w, and 802.1s Multiple Spanning Tree groups and a variety of network management options including: CLI, Telnet, Web-based and SNMP v.1/v.2c/ v.3 management, RMON monitoring, TFTP firmware upgradeability, Port Mirroring for troubleshooting, BootP, and DHCP IP assignment. In addition, the xStack DWS-3227 also supports a variety of advanced traffic management options including: Rate limiting on ingress and egress down to 64k, Broadcast Storm Control, to protect network connectivity in the event of a broadcast storm, and IGMP Snooping, which ‘snoops all Internet Group Multicast Protocol (IGMP) traffic, and prevents unwanted data streams from affecting network or end-station performance. The xStack DWS-3227 also supports L2/3/4 QoS and ACLs, Guest and Private VLANs, 802.1x user authentication and more.
