OVERVIEW:
The HP 2810 Switch Series consists of two switches: the 24-port HP 2810-24G Switch with 20 10/100/1000 ports, and the 48-port HP 2810-48G Switch with 44 10/100/1000 ports. Each switch also has four dual-personality ports for RJ-45 10/100/1000 or mini-GBIC fiber Gigabit connectivity. Ideal for high-performance and secure 10/100/1000 connectivity, the 2810 switch series offers access security and advanced prioritization and traffic-monitoring capabilities. The series is cost-effective and easy to use, with a shallow, 1U form factor that provides operational flexibility for use in smaller wiring closets.
FEATURES:
[ KEY FEATURES ]
• Managed Layer 2 feature set with 24 or 48 Gb ports
• sFlow, source port filtering, enhanced security
• Optional redundant power supply
• Four dual-personality mini-GBIC slots
[ CONNECTIVITY ]
• Dual-personality functionality: Four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, -LH, or 100-FX.
[ RESILENCY AND HIGH AVAILABILITY ]
• IEEE 802.3ad Link Aggregation Protocol (LACP) and HP trunking: Supports up to 24 trunks, each with up to 8 links (ports) per trunk.
• IEEE 802.1s Multiple Spanning Tree: Provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w.
• Optional redundant power supply: Provides uninterrupted power (Provided by HP 600 RPS/EPS).
[ LAYER 2 SWITCHING ]
• VLAN support and tagging: Supports the IEEE 802.1Q (4,096 VLAN IDs) and 256 VLANs simultaneously.
• GARP VLAN Registration Protocol: Allows automatic learning and dynamic assignment of VLANs.
• Jumbo packet support: Supports up to 9,224-byte frame size to improve performance of large data transfers.
[ SECURITY ]
• Port security: Allows access only to specified MAC addresses, which can be learned or specified by the administrator.
• Protected ports: Provides increased security by allowing specified ports to be isolated from all other ports on the switch; the protected port or ports can only communicate with the uplink or shared resources.
• MAC address lockout: Prevents configured particular MAC addresses from connecting to the network.
• Multiple user authentication methods:
- IEEE 802.1X: Industry-standard method of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server.
- Web-based authentication: Similar to IEEE 802.1X, provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant.
- MAC-based authentication: Client is authenticated with the RADIUS server based on client's MAC address.
• Switch management logon security: Can require either RADIUS or TACACS+ authentication for secure switch CLI logon.
• Multiple IEEE 802.1X users per port: Provides authentication of up to two IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication.
• STP BPDU port protection: Blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks.
• Secure FTP: Allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file.
• RADIUS/TACACS+: Eases switch management security administration by using a password authentication server.
• Source-port filtering: Allows only specified ports to communicate with each other.
• Secure Shell (SSHv2): Encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks.
• Secure Sockets Layer (SSL): Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.
[ CONVERGENCE ]
• IP Multicast snooping and data-driven IGMP: Automatically prevents flooding of IP multicast traffic.
• IEEE 802.1AB Link Layer Discovery Protocol (LLDP): Automated device discovery protocol for easy mapping by network management applications
• Per-port broadcast throttling: Selectively configure broadcast control on heavy traffic port uplinks
• Software updates: Free downloads from the Web
[ QUALITY OF SERVICE (QoS) ]
• 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), L3 protocol, TCP/UDP port number, source port, and DiffServ.
• Layer 4 prioritization: Enables prioritization based on TCP/UDP port numbers.
[ MANAGEABILITY ]
• sFlow (RFC 3176): Wire-speed traffic accounting and monitoring
• RMON: 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.
• Troubleshooting: Ingress/egress port monitoring enables network problem-solving
• Single IP address management: Single IP address management for a virtual stack of up to 16 switches
• Multiple configuration files: Allow multiple config files to be stored to flash image
[ EASE OF USE ]
• Locator LED: Allows users to set the locator LED on a specific switch to either turn On, blink, or turn Off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches.
• Friendly port names: Allow assignment of descriptive names to ports.
• Find-Fix-and-Inform: Finds and fixes common network problems automatically, then informs administrator.
• HP/IEEE Auto-MDIX: Automatically adjusts for straight-through or crossover cables on all RJ-45 ports.
