Features

  • Advanced access and distribution for medium businesses and small enterprises seeking to build a secure converged network
  • 48 auto-negotiating 10BASE-T/100BASE-TX/1000BASE-T ports, 4 of which are dual-personality 10/100/1000 or SFP Gigabit ports
  • Wirespeed non-blocking performance: aggregate switching capacity of up to 176 Gbps
  • Layer 2 switching; dynamic Layer 3 routing increases performance and enhances network security
  • Use clustered stacking for up to 32 devices (Switch 4200G, 4500G 5500 and 5500G switches)
  • Add switches to the cluster when needed - without increasing management difficulty and expense - and manage all as a single entity
  • IEEE 802.1X network access control offers standards-based security combined with RADIUS authentication; TACACS+ also supported
  • RADIUS Authenticated Device Access (RADA) provides authentication of attached devices via MAC address for an additional level of endpoint security
  • Automatic assignment of VoIP traffic to dedicated VLANs helps ensure that critical time-sensitive traffic gets the priority needed for quality communications
  • Up to four 10-Gigabit ports per switch using two rear slots and dual-port 10-Gigabit modules; economical CX4 for short-distance stack connections, or XFP for longer 10-Gigabit distances
