Understanding the Supported Layer 2 Protocols in Netvisor ONE


Layer 2 (the Data Link layer) enables the transfer of data between adjacent nodes in a network segment, such as local or wide area networks. Layer 2 frames do not cross the boundaries of the local network. Services provided by Layer 2 include, but are not limited to: frame encapsulation, device  addressing,  error  detection, packet forwarding, loop prevention, flow  control, frame queuing, Quality of Service (QoS), and  traffic segmentation through Virtual LANs (VLANs).


Netvisor ONE supports the following Layer 2 protocols and functionalities:


  • Spanning Tree Protocol (STP)
  • Rapid Spanning Tree Protocol (RSTP)
  • Multiple Spanning Tree Protocol (MSTP)
  • Link Aggregation (LAG)
  • virtual Link Aggregation (vLAG)
  • Link Aggregation Control Protocol (LACP)
  • Link Layer Discovery Protocol (LLDP)
  • Root Guard
  • Fabric Guard
