Aruba 2920-48G switch - 48 ports - Managed - rack-mountable

    • Quality of Service (QoS)
      Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues. Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ. Large buffers: provide graceful congestion management. Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue minimums. Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers.
    • Connectivity
      Flexible 10 Gb/s Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T). Auto-MDIX: provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports. IEEE 802.3at Power over Ethernet (PoE+): provides up to 30 W per port that allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. Two-port stacking module with up to 40 Gb/s per port: optional two-port stacking module allows stacking of up to four switch units into a single virtual device. IPv6: IPv6 host: allows the switches to be managed and deployed at the edge of IPv6 networks. Dual stack (IPv4/IPv6): provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network.
    • Performance
      Energy-efficient design: High-efficiency power supplies: 80 PLUS Silver Certified power supply increases power savings. Energy-efficient Ethernet (EEE) support: reduces power consumption in accordance with IEEE 802.3az. HP ProVision ASIC architecture: is designed with the latest HP ProVision ASIC, providing very low latency, increased packet buffering, and adaptive power consumption. Selectable queue configurations: allows for increased performance by selecting the number of queues and associated memory buffering that best meet the requirements of the network applications.
    • Software-defined networking
      OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) and control (routing decision) paths
    • Convergence
      IP multicast snooping and data-driven IGMP: automatically prevent flooding of IP multicast traffic. IEEE 802.1AB Link Layer Discovery Protocol (LLDP): facilitates easy mapping using network management applications with LLDP automated device discovery protocol. LLDP-MED (Media Endpoint Discovery): defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones. PoE and PoE+ allocations: support multiple methods (automatic, IEEE 802.3at dynamic, LLDP-MED fine grain, IEEE 802.3af device class, or user specified) to allocate and manage PoE/PoE+ power for more efficient energy savings.
    • Management
      SNMPv1, v2, and v3: provides complete support of SNMP; provide full support of industry-standard Management Information Base (MIB) plus private extensions; SNMPv3 supports increased security using encryption. Out-of-band Ethernet management port: enables management over a separate physical management network, keeping management traffic segmented from network data traffic.
    • Resiliency and high availability
      Ring and chain stacking topology: allows failure of a link or switch in the ring of stacked switches, while the remaining connected switches continue operation. IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w. IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 60 static, dynamic, or distributed trunks active across a stack, with each trunk having up to eight links (ports) per static trunk; support trunking across stack members.
