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  fabric-advertisement-network

------  ---------------- ---- -------------- ---------------  --- ----------------------------

Fabric1 b000707:59b6a9ef  0     mgmt           mgmt            48          inband-mgmt

Fabric2 90004eb:59b7da05  0     mgmt           mgmt            8          inband-mgmt

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.
