Extreme Networks D-Series
12-port tabletop edge/workgroup switch with Gigabit Ethernet and optional dynamic policy support, capable of operating with fans turned off.
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 under-tabletop), including an integral Kensington lock and an optional lock box for secure mounting.
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.
-
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
-
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
-
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
-
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
-
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
-
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
-
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
-
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)
