HPE 2800 - J9021a switch - 24 ports - L2 - PoE - managed - Gigabit Ethernet

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.

  • 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
  • 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
  • Traffic prioritization (IEEE 802.1p): allows real-time traffic classification with support for eight priority levels mapped to four queues
  • Dual-personality functionality: four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, and -LH, or 100-FX
  • IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking: support 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
  • VLAN support and tagging: supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously
  • Jumbo packet support: supports up to 9220-byte frame size to improve the performance of large data transfers
  • Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator
  • RADIUS/TACACS+: eases switch management security administration by using a password authentication server
