Aruba 2920 Series


Overview:

The Aruba 2920 Switch Series provides security, scalability, and ease of use for enterprise edge, SMB and branch office networks. A powerful ProVision ASIC delivers low latency, more packet buffering, and adaptive power consumption. This Basic Layer 3 switch series supports modular stacking, 10GbE, PoE+, static and RIP routing, Access OSPF routing, Tunneled Node, ACLs, sFlow, and IPv6. The 2920 delivers a consistent wired/wireless user experience with advanced security and network management tools with Aruba ClearPass Policy Manager and Aruba AirWave. With support from Aruba Central, you can quickly set up remote branch sites with little or no IT support. The 2920 is optimized for Software-defined Networking (SDN) with OpenFlow support.

The Aruba 2920 Switch Series provides cost-effective pay as you grow modular stacking with a 2-port stacking module, support for up to four 10GBASE-T (or SFP+) uplinks and upgradeable power supplies so your network can quickly scale when needed. The robust Basic Layer 3 feature set requires no licensing and includes a limited lifetime warranty.

  • Port security allows access only to specified MAC addresses, which can be learned or specified by the administrator
  • MAC address lockout prevents particular configured MAC addresses from connecting to the network
  • Secure FTP allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
  • Switch management logon security helps secure switch CLI logon by optionally requiring either RADIUS or TACACS+ authentication
  • Custom banner displays security policy when users log in to the switch
  • STP BPDU port protection blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
  • DHCP protection blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
  • Dynamic ARP protection blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
  • STP root guard protects the root bridge from malicious attacks or configuration mistakes
  • Identity-driven ACL enables implementation of a highly granular and flexible access security policy and VLAN assignment specific to each authenticated network user
  • Per-port broadcast throttling configures broadcast control selectively on heavy traffic port uplinks
  • Private VLAN provides network security by restricting peer-to-peer communication to prevent a variety of malicious attacks; typically a switch port can only communicate with other ports in the same community and/or an uplink port, regardless of VLAN ID or destination MAC address
