These Gigabit Ethernet switches deliver outstanding security, reliability, and multiservice support capabilities for robust switching at the edge or aggregation layer of large enterprise and campus networks or in the core layer of SMB networks. The HP A5500G EI Switch Series is comprised of Layer 2/3 Gigabit Ethernet switches that can accommodate the most demanding applications and provide resilient and secure connectivity as well as the latest traffic prioritization technologies to enhance applications on convergent networks. With complete IPv4/IPv6 dual stack support, the series provides investment protection with an easy transition from IPv4 to IPv6 networks. Designed for increased flexibility, these switches are available with 24 or 48 Gigabit Ethernet ports. Power over Ethernet (PoE) and non-PoE models are available with optional GbE and 10 GbE expansion capability. The all-fiber model with dual power supplies is ideal for applications that require the highest availability.
Quality of Service (QoS)
• Storm restraint: allows limitation of broadcast, multicast, and unknown unicast traffic rate to cut down on unwanted broadcast traffic on the network
Management
• Friendly port names: allow assignment of descriptive names to ports
Connectivity
• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Performance
• Nonblocking architecture: up to 176 Gbps nonblocking switching fabric provides wire-speed switching with up to 130 million pps throughput
Resiliency and high availability
• Separate data and control paths: keeps control separated from services and keeps service processing isolated; increases security and performance
Layer 2 switching
• 32K MAC addresses: provide access to many Layer 2 devices
Layer 3 services
• Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet
