Deze switch is refurbished en verkeert in perfecte technische staat.

HP 4210G Switch Series are entry-level Gigabit Ethernet LAN switches with enterprise-class quality of service (QoS), security, and management features, delivering high value for network administrators looking for an economical edge device. Available Power over Ethernet (PoE) models are ideal for voice over IP and wireless networking installations, while non-PoE models are also available for simple port expansion. Dual-personality ports allow flexibility, including the ability to add 10 Gigabit Ethernet capability. Setting them apart from lower-end devices, the series switches support an industry-standard command-line interface, Web-based administration, and SNMP management. In addition, they support Intelligent Resilient Framework (IRF) stacking of up to four units.

Features and benefits

• 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: provides per-port, per-queue egress-based guaranteed bandwidth minimums
• Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network

Management

• 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
• RADIUS accounting support: separates RADIUS accounting server support per SSID; provides detailed session, usage, and billing information for each client activity
• Multiple configuration files: can be stored to the flash image
• Dual flash images: provide independent primary and secondary operating system files for backup while upgrading Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS
• Command-line interface (CLI): provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility
• SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices
• Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring

Connectivity

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