The HP 5500 HI Series of Gigabit Ethernet switch delivers outstanding resiliency, security, and multiservice support capabilities at the edge layer of data center, large campus, and metro Ethernet networks. The switch can also be used in the core layer of SMB networks. The HP 5500 HI Switch Series supports dual power supply & IRF virtual fabric to provide the highest levels of resiliency & manageability. With complete IPv 4/IPv 6 & MPLS/VPLS features, this series provides investment protection with an easy transition from IPv 4 to IPv 6 networks. Features Layer 2 switching DHCP support ARP support MPLS support auto-uplink (auto MDI/ MDI-X) IPv 6 support Spanning Tree Protocol (STP) support Rapid Spanning Tree Protocol (RSTP) support Virtual Route Redundancy Protocol (VRRP) support Multiple Spanning Tree Protocol (MSTP) support Quality of Service (Qo S) Rapid Ring Protection Protocol (RRPP) support Equal-Cost Multipath (ECMP) Bidirectional Forwarding Detection (BFD) STP Root Guard IPv 4 support Advanced classifier-based Qo S Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information;applies Qo S policies such as setting priority level & rate limit to selected traffic on a per-port or per-VLAN basis. Traffic policing Supports Committed Access Rate (CAR) & line rate. Storm restraint Allows limitation of broadcast, multicast, and unknown unicast traffic rate to cut down on unwanted broadcast traffic on the network. Friendly port names Allows assignment of descriptive names to ports. Complete session logging Provides detailed information for problem identification & resolution. Remote configuration & management Available through a secure web browser or a comm&-line interface (CLI). Manager & operator privilege levels Enables read-only (operator) & read-write (manager) access on CLI & web browser management interfaces. Management VLAN Segments traffic to & from management interfaces, including CLI/telnet, a web browser interface, and SNMP. Command authorization Leverages RADIUS 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 SNMPv 1, v 2c, and v 3:facilitate centralized discovery, monitoring, and secure management of networking devices. Remote monitoring (RMON) Uses standard SNMP to monitor essential network functions;supports events, alarm, history, and statistics group plus a private alarm extension group. Remote intelligent mirroring Mirrors ingress/egress ACL-selected traffic from a switch port or VLAN to a local or remote switch port anywhere on the network. Auto-MDIX Automatically adjusts for straight-through or crossover cables on all 10/100 & 10/100/1000 ports. Packet storm protection Protects against broadcast, multicast, or unicast storms with user-defined thresholds. Ethernet OAM Provides a Layer 2 link performance & fault detection monitoring tool, which reduces failover & network convergence times. Flow control Using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations. Jumbo packet support Supports up to 9216-byte frame size to improve the performance of large data transfers. 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. Separate data & control paths Keeps control separated from services & keeps service processing isolated;increases security & performance. Device Link Detection Protocol (DLDP) Monitors link connectivity & shuts down ports at both ends if unidirectional traffic is detected, preventing loops in STP-based networks. 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 & applications. Virtual Router Redundancy Protocol (VRRP) Allows groups of two routers to dynamically back each other up to create highly available routed environments. Dual flash images Provides independent primary & secondary operating system files for backup while upgrading. Multiple configuration files Allows multiple configuration files to be stored to a flash image. IEEE 802.1AB Link Layer Discovery Protocol (LLDP) Automated device discovery protocol provides easy mapping using network management applications. IPv 6 management Future-proofs networking, as the switch is capable of being managed whether the attached network is running IPv 4 or IPv 6;supports pingv 6, tracertv 6, Telnetv 6, TFTPv 6, DNSv 6, and ARPv 6 ...
