HP A5500-24G EI Switch

Description

Storm restraint

It 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

They 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.

Auto-MDIX

It 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.

Separate data and control paths

It keeps control separated 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

It provides 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.
