Description

3COM 48-port baseline 2250 plus switch 10/100 and 2 configurable 10/100/1000 or sfp gigabit ports (retial)

The "smart" 3ComŽ Baseline Switch 2250 Plus is a web-managed Layer 2 10/100 Ethernet switch. It offers enterprise-class features, customized and priced for small- and mid-sized organizations. With an easy-to-use interface and advanced features (VLANs, IEEE 802.1X authentication and Rapid Spanning Tree), this switch is a cost-effective way to provide a converged network.
Features
  • Web-managed Layer 2 10/100 Ethernet switch
  • Forty-eight 10/100 ports and two dual-purpose Gigabit ports (copper or SFP-based fiber)
  • No need to configure the switch if default settings are acceptable
  • If more control desired, the switch interface allows even novice users to quickly and confidently configure the switch
  • Switch can be managed with SNMP-compatible software
  • VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth
  • Voice over IP (VoIP) traffic can be automatically assigned to a voice-dedicated VLAN, optimizing this delay-sensitive traffic
  • With manual link aggregation, group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks
  • IEEE 802.1X network access control provides standards-based security combined with local authentication
  • Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability
  • IGMP snooping and query and multicast filtering optimizes network performance
  • Easy-to-use browser based tools allow remote detection of cable issues
  • Technical Information

    CONNECTORS

  • 48 auto-negotiating 10BASE-T/ 100BASE-TX configured as auto MDI/MDIX
  • 2 dual-personality Gigabit port pairs, configurable as 10BASE-T/ 100BASE-TX/1000BASE-T or SFP

    PERFORMANCE

  • 13.6 Gbps switching capacity, max.
  • 10.1 Mpps forwarding rate, max.
  • Wirespeed performance across ports

  • 256 port-based VLANs (IEEE 802.1Q)
  • Manual link aggregation: 4 trunks, max.
  • 8 ports per trunk, max.
  • Auto-negotiation of port speed and duplex
  • IEEE 802.3x full-duplex flow control
  • IEEE 802.1D Spanning Tree Protocol (STP)
  • IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)
  • Internet Group Management Protocol (IGMP) snooping on Layer 2 interfaces
  • Multicast filtering

    CONVERGENCE

  • 4 hardware queues per port, with IEEE 802.1p Class of Service/Quality of Service (CoS/QoS) on egress
  • Weighted Round Robin queuing
  • Traffic prioritization at Layer 2 using 802.1p QoS
  • Auto VLAN assignment for voice traffic determined by vendor OUI

    SECURITY
