The HP 2530-48 (J9781A) is a 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 the HP 2530-48 (J9781A) Fast Ethernet switches deliver full Layer 2 capabilities with enhanced access security, traffic prioritisation, and IPv6 host support. Features Quality of Service (QoS) Traffic prioritisation (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: prioritises traffic by specifying a port and priority level. VLAN-based: prioritises 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 prioritisation: enables prioritisation 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. Auto-MDIX: adjusts automatically for straight-through or crossover cables on all ports Layer 2 switching VLANs: provides support for 512 VLANs and 4,094 VLAN IDs 16K MAC address table: provides access to many Layer 2 devices GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
