Beskrivning

Produktbeskrivning

The ProCurve Switch 2810 series consists of two switches: the 24-port ProCurve Switch 2810-24G with 20 10/100/1000 ports, and the 48-port ProCurve Switch 2810-48G with 44 10/100/1000 ports.

Viktiga säljargument och fördelar

  • Connectivity
  • Dual-personality functionality: four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
  • Performance
  • 35.7 Mpps at 64 bytes (ProCurve 2810-24G) and 71.4 Mpps at 64 bytes (ProCurve Switch 2810-48G): ten times the bandwidth for low-latency throughput
  • 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
  • Optional redundant power supply: provides uninterrupted power (provided by ProCurve 600 RPS/EPS)
  • Layer 2 switching
  • VLAN support and tagging: supports the IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously
  • GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
  • Jumbo packet support: supports up to 9,216 byte frame size to improve performance of large data transfers
  • Security
  • Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator
  • Protected ports: provides increased security by allowing specified ports to be isolated from all other ports on the switch; the protected port or ports can only communicate with the uplink
  • 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 client's MAC address
  • Authentication flexibility: Multiple IEEE 802.1X users per port: provides authentication of up to two IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
  • BPDU port protection: blocks Bridge Protocol Data Units (BPDU) on ports that do not require BPDUs, preventing forged BPDU attacks
  • 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
  • Source-port filtering: allows only specified ports to communicate with each other
  • Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks
  • Convergence
  • IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic
  • IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
  • Per-port broadcast throttling: selectively configure broadcast control on heavy traffic port uplinks
  • Software updates: free downloads from the Web
  • 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 the 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
  • Manageability
  • sFlow (RFC 3176): wire-speed traffic accounting and monitoring
  • RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
  • Dual flash images: provides independent primary and secondary OS files for backup while upgrading
  • 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, 4200vl series, 6108, 6200yl-24G-mGBIC, and 6400cl series
  • Troubleshooting: ingress/egress port monitoring enables network problem-solving
  • Multiple configuration files: allow multiple config files to be stored to flash image
  • Ease of use
  • Locator LED: allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches
  • Friendly port names: allow assignment of descriptive names to ports
  • Find-Fix-and-Inform: finds and fixes common network problems automatically, then informs administrator
  • ProCurve/IEEE Auto-MDIX: automatically adjusts for straight-through or crossover cables on all RJ-45 ports
