HP E4210G 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.

- 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.
- 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.
- 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 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.
- 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.
- Multiple configuration files: allow multiple configuration files to be stored to flash image.
- VLAN support and tagging: support IEEE 802.1Q, with 4094 simultaneous VLAN IDs.
- GARP VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs.
- IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic.
- Jumbo packet support: supports up to 9220-byte frame size to improve performance of large data transfers.
- 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.
- Static IP routing: provides manually configured Layer 3 routing.
- Access control lists (ACLs): provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number.
- RADIUS/TACACS+: eases switch management security administration by using a password authentication server.
- Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks.
- Secure Web management with HTTPS and SSL: encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.
- IEEE 802.1X and RADIUS network logins: control port-based access for authentication and accountability.
