The D2 workgroup switch doesn’t compromise on features to meet its quiet design.

All of the management and security features you would expect from an enterprise-grade switch are available in this versatile form. Robust Quality of Service (QoS) features support the converged applications required to drive your business. Intelligent queuing ensures that mission-critical applications receive the priority to access much needed network resources.

Security

• Business-oriented, policy-based security* by user, application, protocol, port, or VLAN
• Multiple user authentication methods via IEEE 802.1X, Web portal, and/or MAC address
• Full support 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 and virus quarantine via optional policy license
• Source port pairing
• ARP broadcast protection
• BPDU port protection
• DHCP service protection

Performance

• Aggregate capacity: D2 performs at wire speed per port and provides switching capacity up to 17.86Mpps throughput and 24Gbps 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 twelve 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 disaster-recovery 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 eight 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

Business alignment

• Quiet design and flexible mounting options support evolving workgroup environments
• High-availability design with redundant power (including PoE) assures reliable network operations
• Aligns network resource utilization with business goals and priorities

Operational efficiency

• Temperature-tolerant design enables quiet operation and flexible physical placement of equipment
• Role-based policies simplify addition of new users
• Centralized management reduces network operational expenses

Security

• Integral security without performance degradation
• Network security maintained concurrently with user mobility
• Network resources securely allocated according to user operational roles

Support and service

• Industry-leading customer satisfaction and first-call resolution rates
• Personalized services, including site surveys, network design, installation, and training
• Lifetime warranty
