Features

  • Security:
    802.1X network access control combined with RADIUS authentication ensures secure access to resources. Additionally, RADIUS Authenticated Device Access (RADA) enables authentication of attached devices via MAC address.
    Port-based Access Control Lists (ACLs) effectively enable usage policies at each point of access to the network via the switch.
    Secure Shell (SSHv2) and SNMPv3 support ensure secure management access to switches via authentication and encryption of management traffic.
  • Dynamic Voice over IP:
    Unique Voice VLAN feature detects the presence of IP phones and dynamically assigns switch ports to the Voice VLAN, enabling automated configuration and prioritization of VoIP traffic. This powerful feature minimizes cost and complexity associated with adding or moving IP phones.
  • Performance:
    Aggregate switching capacity up to 13.6 Gbps.
    Dual Gigabit uplinks on each switch unit enable high-speed connections to the network backbone or locally attached servers.
  • Prioritization and Bandwidth Management:
    Eight priority queues per port enable 802.1p Class of Service / Quality of Service (CoS/QoS). Bandwidth rate limiting and protocol filtering capabilities allow the Switch 4500 family to enforce controls on each port for efficient use of network resources and prioritization of \"business-critical\"" or \""time-sensitive\"" applications
