Description:
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.
•Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers. Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues. Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ. Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums. Bandwidth shaping: Rate limiting: provides per-port, ingress-based enforced bandwidth maximums. Guaranteed minimums: provi
•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 swit
•Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports. Dual-personality ality: 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: allow the addition of 10 Gigabit Ethernet connections for uplinks or high-bandwidth server connections; flexibly supports
•IEEE 802.1D Spanning Tree Protocol (STP): provides redundant links 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.
