The 3-stage topology has 2 layers of devices: leaf and spine. All links between leaf and spine must be connected. Spine nodes are not interconnected.
TipIf any devices in a fabric are in "admin-down" state, use of the following commands in that same fabric will not add or delete devices in the fabric: efa fabric device add-bulk and efa fabric device remove.
efa fabric create
efa fabric device add
A device must be registered with the Inventory Service before you can add it to a fabric. However, if you provide a user name and password when you run the command, then the devices are automatically registered with the Inventory Service. See the examples at the end of this procedure.
You can add multiple devices by using the efa fabric device add-bulk command.
TipTo validate fabric port-link status, complete the following operations before running the efa fabric device add-bulk command:
efa fabric device add-bulkoperation.
efa fabric configure
TipThe validation process reports any errors as a response to the efa fabric device add or efa fabric configure operations. You can use the efa fabric error show command to export these errors to a CSV file.
NoteYou cannot change fabric settings after you add devices to the fabric, with the following exceptions:
efa fabric create --name stage3
efa fabric device add-bulk --leaf 10.20.50.205,10.20.50.206,10.20.50.207 --spine 10.20.50.203,10.20.50.204 --name stage3 --username admin --password password
efa fabric configure --name stage3
