HP ProCurve 2800 Switch Series - Overview

Product description

Figure 1: HP ProCurve Switch 2824

Figure 2: HP ProCurve Switch 2848

The HP ProCurve Switch 2800 Series consists of two switches: the 24-port HP ProCurve Switch 2824 with 20 10/100/1000 ports, and the 48-port HP ProCurve Switch 2848 with 44 10/100/1000 ports. In addition, each switch has four dual-personality ports for RJ-45 10/100/1000 or mini-GBIC connectivity. The 2800 series is ideal for secure 10/100/1000 connectivity, and it offers access security and advanced prioritization and traffic-monitoring capabilities. With support for IP static routing, the 2800 series is well-suited for environments that need basic routing at the edge of the network.

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
48 Gbps backplane with up to 34.7 million pps (HP ProCurve 2824) and 96 Gbps backplane with up to 69.8 million pps (HP ProCurve 2848): 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

  • Spanning Tree Protocol (IEEE 802.1D): Provides redundant links while preventing network loops

  • IEEE 802.1w Rapid Convergence Spanning Tree Protocol: Increases network uptime through faster recovery from failed links

  • IEEE 802.1s Multiple Spanning Tree: Provides high link availability in multiple VLAN environments by allowing multiple spanning trees

  • Optional external redundant power supply: Provides uninterrupted power

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

Layer 3 routing
Basic IP routing: enables automatic routing to the connected VLANs and up to 16 static routes-including one default route-in IP networks
Security
  • Dynamic ARP protection: Blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data

  • Dynamic IP lockdown: Works with DHCP protection to block traffic from unauthorized host, preventing IP source address spoofing

  • 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 method 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 client's MAC address

  • Secure FTP: Allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file

  • RADIUS/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

  • 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

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 configures broadcast control on heavy traffic port uplinks

Quality of Service (QoS)
  • Traffic prioritization (IEEE 802.1p): Allows real-time traffic classification into eight priority levels mapped to four 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
  • RMON, XRMON, sFlow, and SMON: Provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events

  • Friendly port names: Allow assignment of descriptive names to ports

  • Auto-MDIX: Automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports

  • Dual flash images: Provides independent primary and secondary operating system files for backup while upgrading

  • Software updates: Free downloads from the Web

  • Stacking capability: Single IP address management for a virtual stack of up to 16 switches, including the HP 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

  • Find-Fix-and-Inform: Finds and fixes common network problems automatically, then informs administrator

  • Troubleshooting: Ingress/egress port monitoring enables network problem-solving

  • Multiple configuration files: Multiple configuration files can be stored to the flash image
