HP A5120 SI Switch Series

Overview:

The HP A5120 SI Switch Series are intelligent, manageable Gigabit Ethernet switches that provide high performance, high-density port access, and simplified installation to maximize the value of your network infrastructure investment. They are typically deployed at the access layer in enterprise networks that require Gigabit Ethernet to the desktop or at the distribution layer in metropolitan area networks (MANs). Wire-speed forwarding delivers optimal throughput and the bandwidth necessary for mission-critical data and high-speed communications. As part of their comprehensive security control, they employ 802.1X authentication to identify users who attempt to access the network. These switches are highly reliable, providing redundancy while eliminating loops in the network. They also offer a range of management protocols to simplify network administration.

• Full wire-speed, multi-layer switching
• High reliability with redundancy
• Comprehensive security control policies
• Diversified Quality of Service (QoS) policies
• Excellent manageability

Features and Benefits:

Quality of Service (QoS)

• Broadcast control — allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network
• Powerful QoS feature — supports the following congestion actions: strict priority (SP) queuing, SDWRR, and SP+SDWRR
• 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 selected traffic on a per-port basis

Management

• Friendly port names — allow assignment of descriptive names to ports
• Remote configuration and management — is available through a secure Web browser or a command-line interface (CLI)
• Manager and operator privilege levels — enable 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
• Dual flash images — provide independent primary and secondary operating system files for backup while upgrading
• Multiple configuration files — can be stored to the flash image
• Complete session logging — provides detailed information for problem identification and resolution
• SNMPv1, v2c, and v3 — 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
• IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — automated device discovery protocol provides easy mapping by network management applications
• Management VLAN — segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and SNMP
• Device Link Detection Protocol (DLDP) — monitors cable between two switches and shuts down the ports on both ends if the cable is broken, preventing network problems such as loops

Connectivity

• Auto-MDIX — automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
• 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 performance of large data transfers
• High-density port connectivity — provides up to 48 fixed 10/100/1000BASE-T ports in an entry-level static Layer 3 switch
• Ethernet OAM — provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network convergence times
• Power over Ethernet Plus (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

Performance

• Nonblocking architecture — up to 104 Gbps nonblocking switching fabric provides wire-speed switching with up to 77.4 million pps throughput
• 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 performance

Resiliency and high availability

• Separate data and control paths — increases security and performance
• Spanning Tree/MSTP, RSTP — provides redundant links while preventing network loops
• IEEE 802.3ad Link Aggregation Control Protocol (LACP) — supports up to 26 trunks, each with 8 links per trunk; supports static or dynamic groups
• Smart link — allows 50 ms failover between links
• Intelligent Resilient Framework (IRF) — creates virtual resilient switching fabrics, where two or more switches perform as a single Layer 2 switch, Layer 3 router; switches do not have to be co-located and can be part of a disaster recovery system; servers or switches can be attached using standard LACP for automatic load-balancing and high availability; simplifies network operation by eliminating the complexity of Spanning Tree, Equal-Cost Multipath (ECMP), or VRRP

Layer 2 switching

• 8K MAC address table — provides access to many Layer 2 devices
• VLAN support and tagging — support IEEE 802.1Q, with 4094 simultaneous VLAN IDs
• IP multicast snooping — automatically prevents flooding of IP multicast traffic
• IGMP and MLD snooping — effectively control and manage the flooding of multicast packets in a Layer 2 network

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
• Dynamic Host Configuration Protocol (DHCP) — simplifies the management of large IP networks; supports client; DHCP Relay enables DHCP operation across subnets
• Loopback interface address — defines an address in Routing Information Protocol (RIP) and OSPF that can always be reachable, improving diagnostic capability

• Static IP routing — provides manually configured routing for both IPv4 and IPv6 networks

• Access control lists (ACLs) — provides IP Layer 2 to Layer 4 traffic filtering; supports global ACL, VLAN ACL, port ACL, and IPv6 ACL
• Identity-driven security and access control —
  • Per-user ACLs — permits or denies user access to specific network resources based on user identity and time of day, allowing multiple types of users on the same network to access specific network services without risk to network security or unauthorized access to sensitive data
  • Automatic VLAN assignment — automatically assigns users to the appropriate VLAN based on their identities
• Secure management access — securely encrypts all access methods (CLI, GUI, or MIB) through SSHv2, SSL, and/or SNMPv3
• Secure File Transfer Protocol (FTP) — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
• Guest VLAN — similar to IEEE 802.1X, it provides a browser-based environment to authenticated clients
• Port isolation — secures and adds privacy, and prevents malicious attackers from obtaining user information
• STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
• STP Root Guard — protects root bridge from malicious attack or configuration mistakes
• DHCP protection — blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
• Dynamic ARP protection — blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
• IP source guard — helps prevent IP spoofing attacks
