       DESCRIPTION

              "This MIB module provides information on Dual Brain Virtual Link
              Trunk(VLT) feature which is a control plane mechanism to provide
              Layer2 multipathing between access network devices (switches or 
              servers) and the core network.
       
              VLT represents a single logical layer 2 domain from the view of 
              downstream devices that have LAG bundles terminating on separate
              chassis in the virtual link trunk domain.

              However, the two VLT chassis are independent L2/L3 switches for 
              devices in the upstream network.

              A sample of VLT scenario:

              Benefits of VLT are as follows: 
               > Allows a single device to use LAG across two upstream devices
               > Eliminates Spanning Tree Protocol (STP) blocked ports
               > Provides a loop-free topology
               > Uses all available uplink bandwidth
               > Provides fast convergence if either the link or a device fails
               > Provides link-level resiliency
               > Assures high availability

              VLT - Virtual Link Trunk 
                     The combined port channel between the VLT peer devices and
                     the downstream device.
       
              VLT Peer device 
                     One of a pair of devices that are connected with the 
                     special port channel known as the chassis interconnect 
                     trunk.
              
              VLT Chassis Interconnect Trunk
                     The link used to synchronize states between the VLT peer 
                     devices. 
              
              VLT domain 
                     This domain includes both VLT peer devices, the VLT chassis
                     interconnect trunk, and all of the port channels in the VLT
                     connected to the downstream devices. 
       
              VLT Backup link 
                     The backup link monitors the vitality of a VLT peer device.
                     The backup trunk sends configurable, periodic heart beat 
                     messages between VLT peer devices.
