Extreme Networks D-Series D2

Sorry, this product is no longer available, please contact us for a replacement.

Overview:

The Extreme Networks D2 is a high-performance Gigabit Ethernet workgroup switch with a high tolerance for environmental temperatures up to 140°F / 60°C. With fans that only operate at extreme temperatures, the D2's very quiet design makes it an ideal solution for classrooms and conference rooms, as well as warm locations with limited ventilation. By providing LEDs on the front, back, and top of the switch, the D2 offers very flexible mounting options (rack, wall, desktop, or undertabletop), including an integral Kensington lock and an optional lock box for secure mounting.

12-port small form factor 10/100/1000 workgroup switch
Quiet design and flexible mounting options for placement in a classroom or a conference room
Temperature-tolerant design enables continuous operation in warm environments
High-availability design with redundant power (including PoE) assures reliable network operations
24 Gbps capacity and 17.86 Mpps

Along with a switch capacity of 24 Gbps, the D2 provides 12 fixed 10/100/1000 Ethernet ports; two of these ports are combo ports and can be accessed via either 100Base-FX or 1 Gbps Small Form Factor Pluggable (SFP) connectors. In order to provide a reliable, high-availability network, both the standard and Power over Ethernet (PoE) D2 models support redundant, external power bricks as well as Link Aggregation Groups (LAGs) for scalable, redundant uplinks.

In conjunction with its non-blocking architecture, the D2's robust Quality of Service (QoS) features enable strong support for converged multimedia networks, including Voice over IP (VoIP), video, as well as all types of data-intensive applications. The D2's highly customizable Layer 2/3/4 packet classification capabilities together with its intelligent queuing mechanisms ensure that mission-critical applications receive prioritized access to network resources.

Making use of Extreme Networks' policy capabilities (included with every D2 after October 1st, 2011), a network administrator can define distinct roles or profiles that represent industry-specific operational groups such as a school or a business. Each defined role is granted individualized access to specific network services and applications (e.g., administrative staff, teacher, student, guest) and these access privileges remain associated with users as they move across both wired and wireless network access points. Users are authenticated via IEEE 802.1X, MAC address, or web authentication, and then assigned a pre-defined operational role ensuring that each user has access to appropriate information, thus aligning network resource utilization with business goals and priorities. In addition, administrators can easily transition from RFC 3580 and complex ACL deployments to the Extreme Networks role-based policy framework in a seamless fashion, without the need to make changes to their RADIUS infrastructure (e.g., adding filter-ID).

In order to sustain a secure, feature-rich and cost-effective network well into the future, the D2 comes with a lifetime warranty.

Features:

Security

Full support, via optional policy license, for port-based policies (PC+Phone)
Acceptable use policy enforcement when deployed with Extreme Networks Network Management Suite (NMS)
Rapid detection, isolation and remediation of threats when deployed with Extreme Networks NMS and Intrusion Prevention System (IPS)
Proactive protection services:
- MAC address lockdown / lockout
- Worm & virus quarantine via optional policy license
- Source port pairing

Performance

Aggregate capacity: D2 performs at wire speed per port and provides switching capacity up to 17.86 Mpps throughput and 24 Gbps bandwidth
Address table size: up to 16,000 addresses are supported
Hardware queues: 8 hardware queues per port are supported

Management

Secure management: authenticated and encrypted SNMPv3 support in addition to SSHv2, Secure Copy, Secure FTP and SSL
Policy support: the D2 supports the creation of 100 unique policy rules and 10 unique masks per port
Port mirroring: mirrors ingress/egress traffic from switch port(s) to a local or remote device for further traffic analysis or compliance purposes
RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, events, filter and packet capture. Note: packet capture is sampling only; packet capture/filter sampling is disabled by default and cannot be enabled on the same interface concurrently with port mirroring
IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
Alias/node table: dynamically updated local directory of attached users and devices used to locate and resolve IP addresses to MAC addresses throughout the network

Convergence

LLDP-MED (Media Endpoint Discovery): a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure and provision network devices such as IP phones
IP multicast snooping (data-driven IGMP): automatically prevents flooding of IP multicast traffic

Connectivity

IEEE 802.3af Power over Ethernet: 100 watts of PoE power is available for distribution across all 12 10/100/1000 ports with the base PoE switch; a maximum of 15.4 W (Class 3) can be delivered to IEEE 802.3af compliant PoE powered devices such as IP phones, wireless access points, and security cameras
15.4 watts of PoE power: can be provided to all twelve ports with the D2-HIPWR-POE option
PoE power management: prioritize which ports receive power and how much power each port may provide
Jumbo frames: enables high-performance remote backup and disasterrecovery services

High Availability

IEEE 802.1s Multiple Spanning Tree Protocol: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; encompasses IEEE 802.1D Spanning Tree Protocol and IEEE 802.1w Rapid Spanning Tree Protocol
IEEE 802.3ad Link Aggregation Control Protocol (LACP): support up to 6 trunks, each with up to 8 ports per trunk
Optional external redundant power supply

Layer 2 Switching

IEEE 802.1q VLAN support and tagging: supports up to 1,024 VLANs simultaneously
IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs
GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs

Quality of Service (QoS)

Traffic classification at layer 2,3,4: enables packet classification and tagging at the network edge based on any of the following attributes: MAC address, physical port, IP address, IP protocol, IP ToS/DSCP, TCP/UDP port, and IP subnet
Traffic prioritization: allows real-time traffic classification into 8 priority levels mapped to eight hardware queues. Weighted round robin (WRR) or strict priority (SP) queuing are supported which keeps low priority traffic from being completely starved of bandwidth. Support for IP Differentiated Services Code Point (DSCP) enables the D2 to enforce requested service levels
