|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 5500 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 a migration path from IPv4 to IPv6 and has hardware support for IPv6. 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 10GbE expansion capability. The all-fiber model with dual power supplies is ideal for applications that require the highest availability.|
- Storm restraint: allows limitation of broadcast, multicast, and unknown unicast traffic rate to cut down on unwanted broadcast traffic on the network. Advanced classifier-based QoS: classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies, such as setting priority level and rate limit, to bi-directional selected traffic on a per-port, per-VLAN, or whole switch basis. Powerful QoS feature: creates traffic classes based on ACLs, IEEE 802.1p precedence, IP, DSCP, or ToS precedence; supports filter, redirect, mirror, or remark; supports the following congestion actions: strict priority queuing (SP), weighted round robin (WRR), SP+WRR, weighted fair queuing (WFQ), and weighted random early discard (WRED). Traffic policing: supports Committed Access Rate (CAR) and line rate.
- Friendly port names: allows assignment of descriptive names to ports. Remote configuration and management: enables configuration and management through a secure Web browser or a CLI located on a remote device. Manager and operator privilege levels: provides read-only (operator) and read/write (manager) access on CLI and Web browser management interfaces. Command authorization: leverages HWTACACS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail. Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS.
- Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports. Flow control: provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations. Jumbo packet support: supports up to 9216-byte frame size to improve the performance of large data transfers. High-density port connectivity: provides up to 48 fixed 10/100/1000BASE-T or 24 SFP 100/1000BASE-X ports in a Layer 2/Layer 3 stackable switch supporting unique IRF stacking. IEEE 802.3at Power over Ethernet (PoE+) support: simplifies deployment and dramatically reduces installation costs by helping to eliminate the time and cost involved in supplying local power at each access point location.
- Nonblocking architecture: up to 192 Gbps nonblocking switching fabric provides wire-speed switching with up to 143 million pps throughput. Hardware-based wire-speed access control lists (ACLs): help provide high levels of security and ease of administration without impacting network performance with a feature-rich TCAM-based ACL implementation.
- Separate data and control paths: separates control from services and keeps service processing isolated; increases security and performance. External redundant power supply: provides high reliability. Smart link: allows 50 ms failover between links. Spanning Tree/MSTP, RSTP: provides redundant links while preventing network loops. Rapid Ring Protection Protocol (RRPP): connects multiple switches in a high-performance ring using standard Ethernet technology; traffic can be rerouted around the ring in less than 50 ms, reducing the impact on traffic and applications.
- 32K MAC addresses: provide access to many Layer 2 devices. IEEE 802.1ad QinQ and selective QinQ: increase the scalability of an Ethernet network by providing a hierarchical structure; connect multiple LANs on a high-speed campus or metro network. GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs. IEEE 802.1ad QinQ: increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on a high-speed campus or metro network. 10GbE port aggregation: allows grouping of ports to increase overall data throughput to a remote device.
- Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet. Dynamic Host Configuration Protocol (DHCP): simplifies the management of large IP networks and supports client and server; DHCP Relay enables DHCP operation across subnets. Loopback interface address: defines an address in Routing Information Protocol (RIP) and Open Standard Path First (OSPF), improving diagnostic capability. User Datagram Protocol (UDP) helper function: allows UDP broadcasts to be directed across router interfaces to specific IP unicast or subnet broadcast addresses and preven
