A small data center (non-Clos) fabric is
used in small data centers.
About this task
Tip
If 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.
Procedure
-
Create the fabric.
-
Add a device to the
fabric.
A device must be registered with 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. If you choose to add multiple devices in bulk, ensure you perform
the following operations first:
- Run the efa inventory
device register --ip <list-of-device-ips>
command.
- Run the efa inventory
device interface list --ip <device-ip> command.
In the output of the command, verify that the states of the port
links are as you expected (in the Admin Status and Oper Status
fields). If not, manually check the physical cabling and fix any
issues. Then continue with the efa fabric device
add-bulk operation.
-
Configure the fabric.
Tip
The 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.
Example
This example creates the fabric.
$ efa fabric create --name extr-fabric --type non-clos
Example
This example adds a device to the fabric.
efa fabric device add --name extr-fabric --ip 10.x.x.x --rack room1-rack1
--username admin --password password
Example
This example adds multiple devices to the
fabric.
$ efa fabric device add-bulk --name extr-fabric --rack room1-rack1
--ip 10.24.80.134,10.24.80.135 --rack room1-rack2 --ip 10.25.225.163,10.25.225.167
Example
This example configures the fabric.
efa fabric configure --name extr-fabric
