The switch line DM3000 is composed by 4 different models that may be installed in standard 19” racks occupying 1U of height. features wire speed switching and model options facing applications L2 and L3.
DM 3000 offers redundant full-range AC/DC power supplies and Multiple standards based SFP modules with various types of fibre optic ranges.
- Wire Speed: L2 and L3 packet switching uses a switch fabric of 12.8 Gbit/s and a forwarding rate of 9.5 million packets per second.
- Stackable: Up to 8 units.
- Advanced QoS Capabilities L2-L4: 8 queues per port with prioritization algorithms.
- Until 4096 VLANs simultaneous: port-based, protocol-based, double tagging (Q-in-Q), dynamic VLAN (GVRP).
- Protection Mechanisms: STP, RSTP, MSTP, ERPS e EAPS.
- A complete centralized FCAPS is available through DMView
management package, using Windows® or Solaris® platforms with the possibility of integration with HP OpenView NNM®. The equipment has a CLI – Command Line Interface – with automatic help in the syntax of commands and parameters, through SSH, Telnet and RS232 console. An internal Web Server with SSL, SNMP agent and RMON is also available.
- DM3000 allows for the creation of complex ACLs – Access Control Lists, with multiple comparison and action parameters, enabling the modification, directioning, discarding or prioritization of packets.
- Tools for network and cable connectivity diagnostics are also available. Cables may be tested for possible interruptions such as short circuits, indicating the approximate distance of the problem. Ports or packet flows may be monitored, allowing for traffic redirection to a specific port.
- In order to simplify the management of updating firmware and configurations, it is possible to store in the equipment 2 different firmware versions and up to 4 different configurations. Firmware upgrades and configuration uploads / downloads may be done through TFTP or HTTP/HTTPS.
Advanced QoS Capabilities
- DM3000 has 8 queues per port with prioritization algorithms that allow various definitions, like: priority definition for certain data flows, weight configuration for each queue, minimum flow rate definition, or even a mix of the above mentioned techniques. Classification of service may be done according to IEEE 802.1p, IP precedence or DSCP fields, TCP and UDP ports, among other possibilities. Data comparison may be done up to L7.
- Bandwidth control has a granularity of 64 kbps for the definition of Committed Information Rate (CIR) and Peak Information Rate (PIR), and may be applied to input or output ports, or to a specific packet flow through ACLs.
- DM3000 has mechanisms that guarantee security in the operation and
maintenance of the installed equipment. All communication protocols use
cryptography and it is possible to specify, through filters, which units of the network may have management access to other switch.
- A highly secure and trustworthy management structure may be built through local and remote syslog, user authentication through RADIUS and TACACS+, e-mail alarm notification, time synchronization, protection against DoS attacks and 802.1x port authentication.
- For Metro Ethernet applications, the quantity of MAC addresses may be limited per port and per VLAN; L2 and L3 protection mechanisms may be used against network attacks, and bandwidth may be limited for broadcast, multicast and destination lookup failure (DLF) traffic.
- Virtual LANs may be built on DM3000 using all of the 4096 VLANs defined in IEEE 802.1Q, offering double tagging (Q-in-Q) functionality and enabling the creation of point-to-point and multipoint-to-multipoint TLS services. VLANs may be defined by protocol, MAC address and IP-subnet. Ports may be overlapped on port-based VLANs, and GVRP protocol may be used for dynamic configuration.
- Spanning Tree protocols are available. RSTP which has shorter conversion times, MSTP for better resource allocation and greater scalability, as well as EAPS protocol, specific for sub-150ms Ethernet rings. Link aggregation functionalities enable the grouping of physical ports into logical ports with automatic load balancing and with typical sub-200ms recovery times. This way it is possible to build Metro Ethernet application topologies with resilient protection and fast failure recovery times.
