Displaying Fabric Instances
To show all the fabric instances and their specific details, use the fabric-show command:
CLI network-admin@switch > fabric-show
name id vlan fabric-network control-network tid
----------- ---------------- ---- -------------- --------------- ---
Fabric1 b000707:59b6a9ef 0 mgmt mgmt 48
Fabric2 90004eb:59b7da05 0 mgmt mgmt 8

Netvisor ONE discovers all available fabric instances by sending out special multicast messages, called global discoveries, whenever a physical port becomes forwarding or on demand. For example, when you execute a fabric-show command, Netvisor ONE sends discovery messages over in-band as well as over the management interface.
After receiving a global discovery message the receiving device responds with a global keep-alive message containing the required fabric and node information.
This local multicast-based discovery mechanism implies that direct Layer 2 connectivity exist between the discoverer and the polled switches.
