The ProCurve Switch 2900 Series consists of two switches: the ProCurve Switch 2900-24G with 24 10/100/1000 ports and the ProCurve Switch 2900-48G with 48 10/100/1000 ports; both have 4 dual-personality ports for 10/100/1000 or mini-GBIC connectivity

Viktiga säljargument och fördelar

  • Performance
  • High-performance architecture: 115 Gbps switching fabric with up to 74 million pps (Switch 2900-24G) and 173 Gbps switching fabric with up to 110 million pps (Switch 2900-48G)
  • Selectable queue configurations: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications.
  • Connectivity
  • Plug-n-Play 10Gbps Ethernet for stacking and uplink: four integrated 10GbE ports (two CX4 and two X2) built-in on the switch
  • Dual-personality functionality: four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
  • Stacking capability: single IP address management for a virtual stack of up to 16 switches, including the ProCurve 2500 series, 2510 series, 2600 series, 2800 series, 2810 series, 2900 series, 3400cl series, 3500yl series, 4100gl series, 4200vl series, 6108, 6200yl-24G-mGBIC, and 6400cl series
  • IPv6 Ready: the switch hardware is capable of supporting IPv6, but IPv6 operation and deployment are not available until enabled via a software update at a later date
  • ProCurve/IEEE Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
  • Resiliency and high availability
  • IEEE 802.3ad Link Aggregation Protocol (LACP) and ProCurve trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk
  • 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
  • Layer 3 routing
  • Layer 3 Routing: Static IP routing provides basic routing; RIP provides RIPv1 and RIPv2 routing
  • Layer 2 switching
  • VLAN support and tagging: support complete IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously
  • GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
  • Jumbo frames: on Gigabit and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services
  • Security
  • Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator
  • MAC address lockout: prevents configured particular MAC addresses from connecting to the network
  • Multiple user authentication methods: IEEE 802.1X - industry standard way of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server; Web-based authentication - similar to IEEE 802.1X, provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant; MAC-based authentication - client is authenticated with the RADIUS server based on the MAC address of the client
  • Authentication flexibility: Multiple IEEE 802.1X users per port provides authentication of up to 8 IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication; Concurrent IEEE 802.1X and Web or MAC authentication schemes per port switch port will accept any of IEEE 802.1X and either Web or MAC authentications
  • BPDU port protection: blocks Bridge Protocol Data Units (BPDU) on ports that do not require BPDUs, preventing forged BPDU attacks
  • Source-port filtering: allows only specified ports to communicate with each other
  • Secure FTP: allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
  • TACACS+: eases switch management security administration by using a password authentication server
  • Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks
  • Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
  • Switch management logon security: can require either RADIUS or TACACS+ authentication for secure switch CLI logon
  • Custom banner: displays security policy when users log in to the switch
  • Quality of Service (QoS)
  • Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into 8 priority levels mapped to 4 queues
  • Class of Service (CoS): sets IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), L3 protocol, TCP/UDP port number, source port, and DiffServ
  • Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
  • Management
  • Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
  • sFlow (RFC 3176) : provides scalable, ASIC-based, wire-speed network monitoring and accounting with no impact on network performance; this allows network operators to gather a variety of sophisticated network statistics and information for capacity planning and real-time network monitoring purposes
  • IEEE 802.1ab LLDP discovery: advertises and receives management information from adjacent devices on a network
  • RMON and XRMON: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
  • Command authorization: leverages RADIUS to link a custom list of CLI commands to individual network administrator's login; also provides an audit trail
  • Friendly port names: allow assignment of descriptive names to ports
  • Dual flash images: provides independent primary and secondary OS files for backup while upgrading
  • Find-Fix-and-Inform: finds and fixes common network problems automatically, then informs administrator
  • Uni-Directional Link Detection (UDLD): monitors a link between two switches and blocks the ports on both ends of the link if the link goes down at any point between the two devices
  • Convergence
  • IP multicast snooping (data-driven IGMP): automatically prevents flooding of IP multicast traffic
  • iSCSI support: enables the deployment of Ethernet storage area network solutions using the iSCSI standard
  • LLDP-MED (Media Endpoint Discovery): a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones
  • Software updates : free downloads from the Web


Ideal for the network edge’s wiring closet connecting to large number of hosts that require high performance uplinks to the distribution/core of the network. This could be driven by existing or future bandwidth-intensive applications such as large database, networked storage, server farm, or multimedia applications such as video streaming.
