Configuring Fabric Guard
Currently, Netvisor ONE detects a Layer 2 loop using by STP, LLDP, or loop detect code. However if a third party device connected to a Pluribus Networks switch consumes LLDP such as a hypervisor vSwitch, and you configure the port as an edge port, Netvisor ONE cannot detect loops on the network.
If you configure a port as fabric-guard port, Netvisor ONE triggers sending global discovery multicast packets on this port after the port is physically up and in an adjacency wait state. If a port with fabric-guard configuration receives a global discovery packet, Netvisor ONE disables the port in the same way LLDP disables the port when receiving messages from the same switch.
In order to re-enable the port once you fix the loop, you must manually enable the port using the command, port-config-modify port port-number enable.
To enable fabric guard, use the following syntax:
CLI (network-admin@Leaf1) > port-config-modify port port-number fabric-guard
To disable fabric guard, use the following syntax:
CLI (network-admin@Leaf1) > port-config-modify port port-number no-fabric-guard
