Management

  • RADIUS accounting support: separates RADIUS accounting server support per SSID; provides detailed session, usage, and billing information for each client activity
  • Uni-Directional Link Detection (UDLD): monitors cable between two switches and shuts down the ports on both ends if the cable is broken, turning the bidirectional link into a unidirectional one; this prevents network problems such as loops
  • Enhanced browser-based interface: allows even the most novice users to configure the switch during initial setup and monitor it during normal operation

Performance

  • Half-/Full-duplex auto-negotiating capability on every port: doubles the throughput of every port
  • VLANs: segment the network by grouping users based on their data or traffic exchange requirements; help ensure improved use of available bandwidth as traffic flow is directed according to the needs of the business
  • Advanced QoS and traffic shaping: traffic prioritization, using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS) with Differentiated Services Code Point (DSCP), helps ensure that critical time-sensitive traffic like voice is given the priority needed for quality communications
  • Rapid Spanning Tree Protocol support: improves network compatibility, scalability, and availability
  • Flexible Gigabit uplink: multiple units can be daisy-chained together via the built-in copper Gigabit uplink port or be connected to a network backbone via SFP-based fiber modules.
  • IGMP snooping: multicast filtering improves network performance, instead of flooding traffic to all ports

Resiliency and high availability

  • IEEE 802.1D Spanning Tree Protocol (STP): provides redundant links while preventing network loops
  • Link aggregation (trunking): allows any number of ports to be grouped together automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks

Security

  • IEEE 802.1X and RADIUS network login: control port-based access for authentication and accountability
