Comprehensive Security
The DXS-3227P is equipped to handle many of today’s emerging security vulnerabilities previously delegated to only standalone firewalls. It incorporates built-in ACLs for searching out and filtering such threats as: Denial of Service attacks, Trojan Horses, Worms, and more. Other access rules can also be set up to prevent network and 802.1x authentication login. In addition, port-based security can also be set up to protect the integrity of the network. With the D-Link Safeguard Engine, the DXS-3227P protects against attacks towards the CPU itself and improves utilization to meet existing network demands to maximize device responsiveness to user configuration activities. In addition, well-known port numbers for allowed applications can be pre-programmed, which will allow these applications faster service and reduce the load on the CPU.
High Availability
The DXS-3227P supports “Shortest-Path” switching, which improves resiliency, uptime and network efficiency. It also supports an optional Redundant Power Supply. It includes support for 802.3ad Link Aggregation, and 802.1w Rapid Spanning Tree for increased network reliability and availability.
Network Management
The DXS-3227P features a variety of network management options: Console CLI, Telnet, Web GUI, SNMPv1/v2/v3, and RMON. It also supports a variety of advanced traffic management options including: Layer 3 Static Routing, Bandwidth Control, Broadcast Storm Control, Private VLANs, and support for IGMP Snooping. D-Link’s exclusive DNA stacking technology is also supported, which allows up to 16 D-Link DXS-3227P switches to be stacked together* and managed as a single unit, regardless of its physical environment.
Advanced QoS
The DXS-3227P provides a robust and consistent set of QoS/CoS, supporting 8 priority queues for 802.1p/ ToS/DiffServ, with classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP. It also provides extensive support for GARP/GVRP, 802.1q, and port-based VLANs for up to 4000 groups per device.
Power over Ethernet IEEE802.3af
Wherever the location—factory, warehouse, campus, small office, or enterprise facility—the challenge and cost of running power to difficult-to-reach locations in order to meet network design can become a disruption to business and a drain on resources. To solve this problem, the DXS-3227P is equipped with 24 10/100/1000BASE-T ports that support the 802.3af PoE protocol. The DXS-3227P is designed to inject up to 15.4 Watts of power per port on all 24 RJ-45 ports to support IP Phones, Access Points, Cameras, and more. The DXS-3227P provides amazing security and flexibility when utilizing the DXS-3227P’s ‘wireless switching’ features. When used to power IEEE 802.3af compliant wireless access points, such as the DWL-2230AP or DWL-7230AP, this ‘wireless-ready’ switch transforms into a complete wireless enterprise solution. For devices that are not 802.3af compliant, the D-Link DWL-P50 PoE adapter can be used to supply power to the device making it fully compatible with any 802.3af compliant switch. The DXS-3227P is ideal for today’s popular PoE applications. Best of all, with 15.4 watts of total power per port, the DXS-3227P will be capable of providing power to future high wattage 802.3af devices such as monitors, scanners, PDA cradles, cell phone chargers and more, insuring a future proof network for years to come.
Wireless AP License
The xStack DXS-3227P switch provides secure, seamless roaming between access points ensuring clear, uninterrupteddataandvoicecommunicationthroughoutyour wireless network infrastructure. The DXS-3227P supports an optional 10, 25, or 50 client AP license, and is capable of supporting up to 50 APs per switch /stack with up to 600 WLAN clients.
Centralized AP Management
The xStack DXS-3227P 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 DXS-3227P includes support for automatic discovery of APs with real-time monitoring, providing visibility into utilization and performance of WLAN users and devices.
Wireless Security
The D-Link xStack DXS-3227P 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, and jamming of the rogue signals.
Seamless Wireless 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 DXS-3227P addresses this problem by bringing AP configurations and support directly into the switch itself. This allows the user to move between access points with seamless mobility. To the users 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.
Inter-Switch Roaming
The xStack DXS-3227P supports roaming of wireless stations between access points attached to different switches. The seamless inter-switch roaming procedure allows a station’s VLAN membership (IP subnet) and QoS parameters to be retained upon roaming between APs connected to multiple switches throughout the network. Inter-Switch roaming is an extremely beneficial feature when creating a large WLAN environment such as a campus or multi-floor office. Inter-Switch roaming allows the user complete freedom to roam between switches located in different buildings or on different floors without disconnection or need for re-authentication.
