About the Default Configuration

By default, Netvisor ONE creates a new fabric instance on VLAN 1.

However, VLAN 1 is often the default VLAN in most networks and therefore security best practices recommend using a non-default VLAN, whenever possible, for maximum robustness and error prevention.

To assign a non-default VLAN, for example, a VLAN ID between 2 and 4093, use the command:

CLI (network-admin@switch) > fabric-create name name-string vlan vlan-id

To change the VLAN ID of an existing fabric, use the command, fabric-local-modify. 

Use the same command to change the fabric administration network, control plane network, and the network to send fabric advertisements.

CLI (network-admin@switch) > fabric-local-modify vlan vlan-id

Note: In order to change the VLAN number of an existing instance you must recreate it. Also, a switch can belong to only one fabric instance.
