HP A5800 switches offer an unmatched combination of Gigabit and 10-Gigabit Ethernet port density, high-availability architecture, and full Layer 2 and Layer 3 dual-stack IPv4 and IPv6 capabilities. Besides wire-speed line-rate performance on all ports, the switches include patented Intelligent Resilient Framework (IRF) technology and Rapid Ring Protection Protocol (RRPP) that allow local or geographically distributed A5800 switches to be interconnected for higher resiliency and performance. Available in PoE and non-PoE models and 1 RU and 2 RU flex chassis configurations, A5800 switches are built on open standards and include an open application architecture (OAA) module slot that that enables flexible deployment options for new services. These versatile switches are ideal for use in the network core for a building or department, or as a high-performance switch in the convergence layer or network edge of enterprise campus networks.Quality of Service (QoS)• Powerful QoS feature: creates traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror, or remark; supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), weighted fair queuing (WFQ), weighted random early discard (WRED), weighted deficit round robin (WDRR), and SP+WDRRManagement• Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI)Connectivity• High-density port connectivity: supports up to 84 1-Gigabit ports per unit/612 per stackPerformance• Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps ensure high levels of security and ease of administration without impacting network performanceResiliency and high availability• Data Center Optimized Design: HP A5800AF-48G Switch (JG225A) supports front-to-back/back to front airflow for hot/cold aisles, rear rack mounts,and redundant hot-swappable AC or DC power and fansManageability• Full-featured console: provides complete control of the switch with a familiar command-line interface (CLI)Layer 2 switching• GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs
