Power over Ethernet for voice, video, and wireless
Energy-efficient design and quiet operation
Rack-mountable and compact form factors
Introduction
The HP 2520 switch series is ideally suited for small and medium businesses looking to deploy voice, video, or wireless solutions that
require Power over Ethernet (PoE) connectivity. The series consists of three switches: the HP 2520-8-PoE, 2520-24-PoE, and 2520-8G-
PoE Switches. The three models offer a choice of either Fast Ethernet or Gigabit Ethernet connectivity. All models also include support
for dual-personality Gigabit Ethernet ports that can be used for either copper or fiber connectivity. All products are fully managed via
SNMP, command-line interface (CLI), and graphical user interface (GUI) and offer a Layer 2 feature set. In addition, the products provide
deployment flexibility with compact, quiet, and energy-efficient designs.
Features and Benefits
Quality of Service (QoS)
Selectable queue configuration : allows you to increase performance and/or traffic reliability by selecting the number of
queues that best meet the requirements of your network applications; switch will map 8 priorities to either 2 or 4 queues
Simplified QoS configuration :
Port-based: prioritize traffic by specifying a port and priority level
VLAN based: prioritize traffic by specifying a VLAN and priority level
IEEE 802.1p traffic prioritization : honors and sets IEEE 802.1p priority in the VLAN tag
Type of service :
IP precedence : honors IP precedence bits and allows mapping to a priority queue
Differentiated Services Code Point values : honors Differentiated Services Code Point (DSCP) bits and allows mapping to
a priority queue
Flow control : helps ensure reliable communications during full-duplex operation
Management
Choice of management interfaces :
Web graphical user interface (GUI): easy-to-use graphical interface allows configuration of the switch from any Web
browser
Command-line interface (CLI): robust command-line interface provides advanced configuration and diagnostics
Simple Network Management Protocol (SNMPv2c/SNMPv3): allows switch to be managed with a variety of third-party
network management applications
Integration with HP PCM : enables discovery, mapping, logging, and configuration via HP PCM, which is available as a free

attacks
Multiple configuration files : configuration file management tools allow up to three configuration files to be managed and
stored on the switch
Dual flash images : provide independent primary and secondary operating system files for backup while upgrading

also provides an audit trail
Logging : local and remote logging of events via SNMP (v2c and v3) and syslog
IPv6 host : allows switches to be managed using IPv6
RMON : provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Find-Fix-Inform : finds and fixes common network problems automatically, then informs the administrator
Front-panel LEDs :
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
Per-port LEDs : provides an at-a-glance view of status, activity, speed, and full-duplex operation
Power and fault LEDs : display any issues
Connectivity
Auto-MDIX : automatically adjusts for straight-through or crossover cables on all ports
Small Form-Factor Pluggable (SFP) slots : dual-personality ports allow for either copper or fiber connectivity such as Gigabit-
SX, -LX, -LH, and -BX or 100-FX and -BX
IEEE 802.3af Power over Ethernet : provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP
phones, wireless access points, and security cameras (see product specifications for total PoE power available); supports some
prestandard PoE devices (see product FAQs for more details)
RJ-45 serial console port : front of unit location provides easy access to the switch CLI
Performance
Switch on a chip : provides highly integrated, high-performance switch design with a non-blocking architecture
Jumbo packet support : supports up to 9216-byte frame size to improve performance of large data transfers (2520G switch)
Resiliency and high availability
Port trunking and link aggregation :
Trunking: supports up to eight links per trunk to increase bandwidth and create redundant connections
IEEE 802.3ad Link Aggregation Protocol (LACP): eases configuration of trunks through automatic configuration
IEEE 802.1s Multiple Spanning Tree Protocol (MSTP): provides high link availability in multiple VLAN environments by allowing
multiple spanning trees; provides legacy support for IEEE 802.1w (Rapid Reconfiguration of Spanning Tree Protocol) and IEEE
802.1d (Spanning Tree Protocol)
Layer 2 switching
VLAN support and tagging : supports the IEEE 802.1Q (4,094 VLAN IDs) and up to 256 port-based VLANs simultaneously
GARP VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs

Broadcast control : allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network
Security
Manager and operator privilege levels : enables read-only (operator) and read-write (manager) access on management
interfaces
RADIUS/TACACS+ for management access authentication : eases switch management security administration by using a
password authentication server
Secure protocols for encryption of management traffic :
Secure Shell (SSHv2): encrypts all transmitted data for secure, remote 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
Simple Network Management Protocol (SNMP) v3: allows encryption of traffic between switch MIBs and network
management software
Secure FTP (SFTP): encrypts uploads and downloads of configuration file
Protected ports : prevents designated ports from communicating with each other while allowing access to unprotected ports
Port security : allows access only to specified MAC addresses, which can be learned or specified by the administrator
MAC address lockout : prevents particular configured MAC addresses from connecting to the network
MAC address lockdown : allows only specified MAC addresses access to the network on a specified port
Denial-of-service (DoS) attack filtering : automatically filters and drops common DoS attack traffic types
User authentication for port access :
IEEE 802.1X : utilizes an industry-standard user authentication with an IEEE 802.1X supplicant on the client in conjunction
with a RADIUS server
Web-based : similar to IEEE 802.1X, it provides a browser-based environment to authenticate clients
MAC-based : client is authenticated with the RADIUS server based on MAC address
Concurrent authentication schemes : each switch port will accept up to two sessions of IEEE 802.1X, Web, and/or MAC
authentications concurrently
Custom banner : displays security policy when users log in to the switch
Spanning Tree Protocol Bridge Protocol Data Unit (BPDU) port protection : blocks BPDUs on ports that do not require BPDUs,
preventing forged BPDU attacks
Spanning Tree Protocol Root Guard : when running the spanning tree protocol, protects root bridge from malicious attack or
configuration mistakes
Physical security :
