2 AOS-CX Onboarding to Central with Template groups

Add AOS-CX switches to Central

device inventory with subscription and

application assignment

Create template groups with the golden

template for each device persona in

Central

Upload variables file for each of the

template groups created (contains

device serial and mac)

(Optional)

Set firmware compliance for the

intended AOS-CX version in Central

‘default’ group and all newly created

template groups

Connect the uplink from AOS-CX

switch to Central

Is the switch in

factory default

state or zeroized?

Yes

Is this a VSF

stack device?

Note: For VSF stack

formation in Central TG, all

stack members must be in

factory default state or

zeroized and only conductor

and standby member need

uplink connectivity

Yes

Switches

onboard to

‘default’ group

(must for VSF).

Firmware

compliance

kicks in

Move only the

conductor to

pre-configured

VSF config is

pushed to

conductor and

other members

join the group

Pre-provision

switch to TG.

Switch onboards

to ‘default’

group if not pre-

provisioned

Move switch to

group that is pre-

configured with

desired template

config for config

push and sync

Note: For VSX config, both primary and

secondary member should be managed with

a single template and no vsx sync config

Pre-provision

switch to TG.

Switch are listed in

Central as ‘un-

provisioned’ if they

are not pre-

provisioned

Move un-

provisioned

switches to the

desired TG for

firmware

compliance and

configuration push

Note: For VSF stacks

formed outside of Central,

move only the conductor

from unprovisioned to the

intended TG. Members

join automatically after

successful config push.

Note: If firmware compliance is set for the

TG, then template/s should be created for

the specific firmware version instead of ‘All’

Note:

• Users have the option to import configuration from the switch to the template in TG if the template has not been

setup already.

• If users wish to move devices to their intended group without triggering the configuration push from Central

immediately, they have the option to disable auto-commit for the TG and choose the ‘commit now’ option to

trigger configuration push and synchronization with Central when needed.

3 AOS-CX onboarding workflows with Template Groups

3.1 ZTP onboarding and firmware upgrade for factory default (standalone)

switches

1. Create template group in Central with the software version in template/s set to the desired version

2. Add the desired configuration (golden template) and variables for the TG

3. Set firmware compliance for the group to the desired switch version

4. In the CCS device inventory, add the serial number and mac address of the new switches. Also add assignment

and subscription for them

5. In Central  Organization, pre-provision the devices to the desired TG. Optionally, users can choose to have

the devices onboarded to the ‘default’ group and then move them to the desired TG

6. The desired configuration is pushed to switches and status shows ‘in sync’ in Central

3.2 VSF stack auto-join and onboarding in Central template groups

1. The VSF auto-join functionality with template groups is available for AOS-CX releases 10.07 and higher

only. For AOS-CX releases 10.06 and lower, the VSF stack will need to be formed outside of Central.

2. All members of the VSF stack should be in their factory default state and physical links for VSF should be

connected. Central uplink connectivity is required only for conductor and standby member

3. Create TG with desired configuration for the VSF stack

4. Add all members to CCS device inventory along with assignment and subscription

5. Set firmware compliance in the ‘default’ group to the desired version for the switches

6. All members onboard to the default group (must for VSF)

7. Move only the conductor to the pre-configured template group

8. All other members join the VSF stack join the group automatically and have their configuration synced

Note: For VSF stacks that have already been setup before onboarding to Central, the uplink connectivity to Central

should be setup only for the conductor initially. Once the stack is moved to the desired TG, the standby uplink can be

connected

3.3 Onboarding pre-provisioned switches to Central

1. In the CCS device inventory, add the serial number and mac address of the switches. Also add assignment and

subscription for them

2. Connect the Central uplink for the switches. They are onboarded to the ‘un-provisioned’ devices list if not pre-

provisioned to a group already

3. Move the devices to the desired template group

4. Create a new template and import existing configuration from the switch/s

5. Upload variables file to manage multiple switches in the same template group

6. Configuration is pushed from Central to all devices in the group

3.4 One Touch Provisioning (OTP)

This option is useful for someone who wants to initially determine the switch’s management IP address, VLAN,

trunk/native status and/or the management VLAN does not offer DHCP. It is also useful in cases where the VSF stack

is pre-configured outside of Central before onboarding.

With this scenario, you have several initial config options:

Using the console port – RJ45, USB-C

Using the CX mobile app via Bluetooth

The below procedure defines the workflow for setting up a VSF stack using the CX mobile app and pushing initial

configuration (non-default) to the AOS-CX switch before onboarding to Central –

Step 1 – Setup VSF stack using CX Mobile App

1. Power all devices out-of-box

2. Cable and connect all devices members of the VSF stack as per intended VSF topology.

3. Connect the Bluetooth Dongle to the first switch that is destined as VSF-Master member.

4. On the mobile device discover and connect to the switch destined as VSF-Master member via Bluetooth

5. Open CX Mobile App and navigate to Initial Config

6. On the Device Login screen set a password for “admin” user

7. On Initial Config start the stack configuration

(Note: Stacking Automation will result in the device that is currently connected via Bluetooth becoming the Master

of the stack.)

8. The VSF-Master switch will discover the other connected devices in VSF stack (step 2) based on Link Layer

Discovery Protocol (LLDP) neighbors. The app will also collect information from the BLE beacons sent out

by the neighboring switches. The app will check to ensure that the MAC address from LLDP and the BLE

beacons match.

(Note: Any beacons with a MAC address that do not match the LLDP table will be disregarded.)

9. Assign a member as the VSF-secondary and change member IDs from the Stack Topology view.

- With the stack member selected change the member ID number using the dropdown selector or designate

it as the stack secondary using the checkbox and you can see the connection of VSF links.

- Once done editing the member, tap the Back button at the bottom of the screen.

- After all members are assigned their settings, tap Configure Members to continue.

Single VSF link Multi VSF lik

10. The CX Mobile app will then apply member IDs and secondary configuration to all switches in the stack,

which will cause each member other than the primary to reboot.

11. Once all switches have rebooted and joined the stack, the message Stack Set Up Successful! will be displayed;

tap Configure Stack to continue.

Step 2 - Apply custom template from CX Mobile App

1. Upload the template file to the CX mobile App.

2. Input the required information prompted by the template (example: VLAN 802 IP address and netmask,

default gateway, DNS server)

(Note: the CX mobile app will use the DryRun API to validate configuration entered into the template before actually

incorporating it into the running configuration)

3. Once the configuration is verified the device will be configured with a template. Before deploying action, the

proposed candidate configuration is shown for review to the operator.

Step 3 - Apply full template from Central

Note: CX VSF stack be setup using CX Mobile app before onboarding to Central. Any modifications to stack

configuration also require the stack to be taken offline from Central and then onboarded back. Details for setting up

VSF stack are available in the following slides

1. Create template group for the VSF stack in Central.

2. Create the VSF template in Central (copy & paste form a fully configured VSF switch)

Note: Update password to plaintext in Central template

3. Add and subscribe the Master and Standby members of the VSF stack in Central (other members are optional)

4. Assign the stack members to the template group in Central.

5. VSF stack will show as a single entity under switches for the template group and details of members and links

will be available.

4 Managing AOS-CX switches in template groups

4.1 High-level definitions

Groups:

Aruba Central supports provisioning AOS-CX switches in UI and template groups. Template groups allow you to

configure devices using CLI-based configuration templates. UI groups allow you to configure devices using UI-based

configuration options. The scope of this document is restricted to template group workflows.

Templates:

Templates in Aruba Central refer to a set of configuration commands that can be used by administrators for

provisioning devices in a group. Configuration templates enable administrators to apply a set of configuration

parameters simultaneously to multiple switches in a group and thus automate switch deployments.

• Note: When importing the running configuration of an AOS-CX switch to Aruba Central using template

configuration, the original running configuration that was present on the device when it was onboarded will

be used. Any changes made to the running configuration after initial onboarding of the AOS-CX switch will

not be reflected in the import running configuration feature.

Variables:

Aruba Central allows you to configure multiple devices in bulk using templates. However, in some cases, the

configuration parameters may vary per device. To address this, Aruba Central identifies some customizable CLI

parameters as variables and allows you to modify the definitions for these variables as per your requirements.

You can download a sample file with variables for a template group or for the devices deployed in a template group,

update the variable definitions, upload the file with the customized definitions, and apply these configuration changes

in bulk.

• Note:

o Variables are associated to a device and not to a group. If you move a device between

groups, variables remain with the device.

o Variables are displayed as part of the group to which the device belongs. After you upload

the variables for a device, the association would stay in the system even if the device is moved to a UI

group or template group.

o If the device is part of a UI group, variables are unused and not displayed in the UI. Aruba Central

ignores the variables.

o If the device is moved to a template group, variables are displayed in the UI and used for

configuration purposes.

Default group:

A factory default (or zeroized) AOS-CX switch will be added to the default groups when onboarded to Central if it

was not pre-provisioned to a group already. The default group is a UI group.

• Note: For successful ZTP onboarding of AOS-CX VSF stacks, users should not set a group level password or

any configuration in the default group since that will undo the factory default state of the VSF stack members.

Unprovisioned devices:

Pre-configured (non-factory-default) switches are listed under unprovisioned devices in Central if they have not been

pre-provisioned to a group already. ‘Unprovisioned’ is not a group in Central but only a placeholder for the switches.

4.2 Managing device types in Central

4.2.1 VSF stack formation with Template groups

Pre-requisites –

 All switches in the VSF stack are added to the device inventory and assigned with a valid license.

 All switches in the VSF stack are set to the factory default configuration.

 All switches in the VSF stack are running AOS-AOS-CX 10.07 or later firmware versions.

 All switches in the VSF stack are of the same switch series.

 Members in the VSF stack other than the conductor should not have uplink connectivity. Otherwise, auto-

stacking will not work.

 The VSF member 1 line must be present in the configuration template for stackable AOS-AOS-CX switches

running 10.07 or later versions. This is required to apply configuration to the switches. Also, the vsf member

1 line cannot be removed from the template.

 All switches in the VSF stack must be physically connected in the chain or ring topology on the ports reserved for

auto-stacking. For auto-stacking to work, the members should be connected in the direction of the higher

denomination port to the lower denomination port.

The following ports are reserved for auto-stacking:

o 24-port switch models— Ports 25 and 26

o 48-port switch models— Ports 49 and 50

Connect the uplink to the switch that should act as the conductor. The switch will connect to Aruba Central as a

standalone device and will be added to the assigned template group.

Once the switch is added to the template group, Aruba Central pushes the template group configuration to the switch.

After the configuration is pushed, starting with the second switch, each switch in the stack reboots automatically and

joins the stack one after another. Each member may take up to 10 minutes to join the stack.

4.2.2 VSX configuration management with Template groups

Aruba Central provides support for VSX by displaying information about the configurations of the switches and the

status of the inter-switch link (ISL) between the switches.

It is recommended to have a single template (with variables file) manage configuration for both the primary

and secondary VSX members.

The following limitations apply when configuring VSX or viewing VSX data for AOS-AOS-CX switches in Aruba

Central:

 Enabling VSX synchronization using template configuration in Aruba Central is not recommended. By

enabling VSX synchronization, the peer switch might get into an unknown configuration state.

 Last synced data is not displayed on the VSX page in Aruba Central.

5 Moving devices from TG to UI group (brownfield)

Aruba Central supports managing AOS-CX switches configuration using UI groups. You can configure AOS-

CX switches that are added to a UI group, using the UI options and MultiEdit mode.

One of the recommended workflows for managing AOS-CX switches in UI groups is to first onboard them to

template groups and then move them to UI groups while preserving the full configuration of the switches.

This can be done at the Global  Groups management tab in Central where you have the option to retain

configuration when the AOS-CX switch is moved from TG to UI group –
