Overview HP A5800 switches offer an unmatched combination of Gigabit & 10-Gigabit Ethernet port density, high-availability architecture, & full Layer 2 & Layer 3 dual-stack IPv 4 & IPv 6 capabilities. Besides wire-speed line-rate performance on all ports, the switches include patented Intelligent Resilient Framework (IRF) technology & Rapid Ring Protection Protocol (RRPP) that allow local or geographically distributed A5800 switches to be interconnected for higher resiliency & performance. Available in Po E & non-Po E models & 1 RU & 2 RU flex chassis configurations, A5800 switches are built on open standards & include an open application architecture (OAA) module slot that that enables flexible deployment options for new services. These versatile switches are ideal to be used 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. Features Quality of Service (Qo S) • Powerful Qo S feature: creates traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, DSCP or Type of Service (To S) 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), & SP+WDRR Management • Remote configuration & management: is available through a secure Web browser or a comm&-line interface (CLI) Connectivity • High-density port connectivity: supports up to 84 1-Gigabit ports per unit/612 per stack Performance • Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps ensure high levels of security & ease of administration without impacting network performance Manageability • Full-featured console: provides complete control of the switch with a familiar comm&-line interface (CLI) Layer 2 switching • GARP VLAN Registration Protocol (GVRP): allows automatic learning & dynamic assignment of VLANs Layer 3 services • Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
