Overview

The HP E4800G Switch Series is a Gigabit switch family that delivers outstanding security, reliability, and multi-service support capabilities for robust switching at the edge or aggregation layer of large enterprise and campus networks, or in the core layer of medium- and small-sized enterprise networks. The family consists of Layer 2/3/4 Gigabit Ethernet switches that can accommodate the most demanding applications, providing resilient and secure connectivity and the latest traffic-prioritization technologies to optimize applications on converged networks. Designed for maximum flexibility, these switches are available with 24 or 48 Gigabit ports. Power over Ethernet (PoE) and non-PoE models are offered with optional 10 Gigabit expansion capability and small form-factor pluggable (SFP) mini-GBIC Gigabit combo ports for fiber flexibility. The all-SFP model with dual power supplies, for highest availability applications, allows for very flexible fiber with copper Gigabit connectivity.

Features

•	IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol provides easy mapping by network management applications

•	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

•	Management VLAN: segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and SNMP

•

Uni-Directional Link Detection (UDLD): monitors cable between two switches and shuts down the ports on both ends if the cable is broken turning the bi-directional link into uni-directional; this prevents network problems such as loops (may not apply to all models; see specifications for more details)

•	Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports

•	Dual-personality functionality: includes four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, -LH, or 100-FX

•	IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras

•	Optional 10 Gigabit Ethernet ports: add 10 Gigabit Ethernet connections for uplinks or high-bandwidth server connections; flexibly supports XFP, SFP+, or CX4 local connections

•	High-bandwidth CX4 local stacking: when locally stacked using CX4 local stacking, achieves 12 Gbps per connection, allowing for up to 96 Gbps total stacking bandwidth (full duplex) in a resilient stacking configuration

•	IEEE 802.1D Spanning Tree Protocol (STP): provides redundant links while preventing network loops

•	IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees

•	Virtual Router Redundancy Protocol (VRRP): allows groups of two routers to dynamically back each other up to create highly available routed environments

•	Device Link Detection Protocol (DLDP): monitors link connectivity and shuts down ports at both ends if unidirectional traffic is detected, preventing loops in STP-based networks

•

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

•

Advanced IRF technology stacking: – Locally connect up to nine E4800G switches using 10 Gigabit or CX4 local connections. – Improve resiliency by spreading aggregated links across multiple stacked units. – See faster performance through a distributed routing architecture where locally bound traffic is handled at each unit. – Simplify management with single IP management and a unified control interface per stack.

•	RMON (remote monitoring): provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events

•	Dual flash images: provides independent primary and secondary operating system files for backup while upgrading

•	Full-featured console: provides complete control of the switch with a familiar command-line interface (CLI)

•	Web interface: allows configuration of the switch from any Web browser on the network
