The HP 2530 Switch Series consists of 12 fully managed Layer 2 edge switches that deliver cost-effective, reliable, secure, and easy-to-use connectivity to business networks. Designed for entry-level to midsize enterprise networks, these Gigabit and Fast Ethernet switches deliver full Layer 2 capabilities with optional PoE+, enhanced access security, traffic prioritization, and IPv6 host support.

The HP 2530 Switch Series offers uplink flexibility with four Gigabit Ethernet uplinks on all 24- and 48-port models. Gigabit Ethernet uplinks are four small form-factor pluggable (SFP) slots for fiber connectivity on the 24- and 48-port Gigabit Ethernet models.

The Fast Ethernet 24- and 48-port models have two SFPs and two RJ-45 Gigabit uplinks. The compact and fanless 8-port switches offer additional flexibility with two dual-personality ports that can be used as either RJ-45 Gigabit Ethernet or SFP ports.

For customers implementing Power over Ethernet for voice, video, or wireless deployments, the HP 2530 PoE+ switches are IEEE 802.3af and IEEE 802.3at compliant with up to 30 W per port. The switch series is easy to use, deploy, and manage via SNMP, CLI, and Web GUI.
 
It offers flexible wall, table, and rack mounting; quiet operation with fanless and variable speed fan models; and improved power savings, with features such as IEEE 802.3 az (Energy Efficient Ethernet). These switches include a lifetime warranty, as well as all software releases and technical phone support.    
 
 

Features

Quality of Service (QoS)

  • Traffic prioritization (IEEE 802.1p): allows real-time traffic classification with support for eight priority levels mapped to either two or four queues; uses weighted deficit round robin (WDRR) or strict priority (SP)
  • Simplified QoS configuration: Port-based: prioritizes traffic by specifying a port and priority level. VLAN-based: prioritizes traffic by specifying a VLAN and priority level.
  • Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
  • Rate limiting: sets per-port ingress enforced maximums for all ingressed traffic or for broadcast, multicast, or unknown destination traffic
  • Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers

Management

  • Choice of management interfaces: Web graphical user interface (GUI): HTML-based easy-to-use graphical interface allows configuration of the switch from any Web browser. Command-line interface (CLI): provides advanced configuration and diagnostics through a robust CLI. Simple Network Management Protocol (SNMPv1/v2c/v3): allows a switch to be managed with a variety of third-party network management applications.
  • Virtual stacking: provides single IP address management for up to 16 switches
  • sFlow (RFC 3176): delivers wire-speed traffic accounting and monitoring configured by SNMP and CLI with three terminal encrypted receivers
  • IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automates device discovery protocol for easy mapping by network management applications
  • Logging: provides local and remote logging of events via SNMP (v2c and v3) and syslog; provides log throttling and log filtering to reduce the number of log events generated

Connectivity

  • IPv6: IPv6 host: allows the switch to be deployed and managed at the edge of an IPv6 network. Dual stack (IPv4/IPv6): supports connectivity for both protocols; provides a transition mechanism from IPv4 to IPv6. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network.
  • IEEE 802.3af Power over Ethernet (PoE): 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
  • IEEE 802.3at Power over Ethernet Plus: provides up to 30 W per port to IEEE 802.3 for PoE/PoE+-powered devices such as video IP phones, IEEE 802.11n wireless access points, and advanced pan/tilt/zoom security cameras (see product specifications for total PoE power available)
  • Auto-MDIX: adjusts automatically for straight-through or crossover cables on all ports
  • Pre-standard PoE support: detects and provides power to pre-standard PoE devices; see the list of supported devices in the product FAQ at www.hp.com/networking/support

Layer 2 switching

  • VLANs: provides support for 512 VLANs and 4,094 VLAN IDs
  • Jumbo packet support: supports up to 9220-byte frame size to improve the performance of large data transfers; 8- and 24-port Fast Ethernet models automatically support up to 2000-byte frames with no configuration needed
  • 16K MAC address table: provides access to many Layer 2 devices
  • GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
  • Per-VLAN Spanning Tree Plus (PVST+): allows each VLAN to build a separate spanning tree to improve link bandwidth usage in network environments with multiple VLANs
