2800 series at-a-glance

Model Port Physical characteristics Performance Switch 2810-24G (J9021A) 20 RJ-45 10/100/1000 ports (IEEE 802.3 Type 10Base-T, IEEE 802.3u Type 100Base-T, IEEE 802.3ab Type 1000Base-T) 1 RJ-45 serial console port 4 Dual Personality Ports each port can be used as either an RJ-45 10/100/1000 port (IEEE 802.3 Type 10Base-T, IEEE 802.3u Type 100Base-TX, IEEE 802.3ab 1000Base-T Gigabit Ethernet) or an open mini-GBIC slot (for use with mini-GBIC transceivers) 12.7 x 17.4 x 1.7 in. (32.26 x 44.2 x 4.32 cm) 1U height weight: 7.21 lb (3.27 kg) Latency: < 5.6 s (FIFO 64-byte packets) Throughput: up to 35.7 million pps Switching capacity: 48 Gbps MAC address table size: 8000 entries

• 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

• Dual-personality functionality: four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH

• 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)

• 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 packet support: supports up to 9,216 byte frame size to improve performance of large data transfers

• 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

• 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

• 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

• 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

• 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 10/100/1000 ports

• 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: provide 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, 3400cl series, 6108, 6400cl series, 4200vl series, and 4100gl series

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

• Multiple configuration files: allow multiple config files to be stored to flash image

• IEEE 802.1ab LLDP discovery: advertises and receives management information from adjacent devices on a network

• Per-port broadcast throttling: selectively configure broadcast control on heavy traffic port uplinks

• Software updates: free downloads from the Web
