Aruba Switch Stack

A switch stack is a set of switches that are interconnected through stacking ports. The switches in a stack elect a primary switch called Commander and a backup switch as Standby. The remaining switches become Members of the stack. The following table lists the switches support stacking:

For more information on topology and configuration of switch stacks, see the HPE ArubaOS-Switch Management and Configuration Guide for the respective switch series.

Provisioning Switch Stacks in Central

The switch elected as the commander establishes a WebSocket connection to Central. The following criteria apply to provisioning and management of switch stacks in Central:

Switch stacks can be added only to a template group and cannot be moved to a UIUser Interface. group.

If the standalone switches in a group join to form a switch stack, the switch is moved to the Unprovisioned state.

If a switch stack is moved from a pre-provisioned group to an existing group in the UIUser Interface., it will be moved to Unprovisioned state.

After forming a switch stack, you can remove a member and erase its stacking configuration. However, the member can join Central as a standalone switch only after it is deleted from the switch stack.

Configuring Switch Stacks

The switch stacks are provisioned under template groups in Central. The template groups allow you to configure and modify the settings of a switch stack using configuration templates.

When uploading a configuring template, ensure that the variables are uploaded for all the members of the stack. The template is applied with the variables of the member that is elected as the commander.

To create a configuration template for switch stack, complete the following steps:

1. From the appShort form for application. It generally refers to the application that is downloaded and used on mobile devices. selector, click Wired Management.

2. From the group selector, select template group to which the switch stack is assigned. The menu options for configuring devices in the template groups are displayed.

3. Click Templates. The Templates page opens.

4. Click + to create a template for the Aruba switch stack.

5. Specify a name for the template.

6. Select Aruba Switch from the Device drop-down list.

7. Select the Aruba Switch model in the Model drop-down list.

8. Select the Aruba Switch software version in the Version drop-down list.

9. Enter the template text in the Template box.

10. Click Save.

 

Central does not support the use of part number (J-number) in place of Switch model number in configuration templates for the Aruba switch stack.

The following pre-defined variables are refreshed and re-imported from a switch stack when a new stack member is added or removed, or when a failover occurs.

_sys_template_header

_sys_module_command

_sys_stack_command

_sys_oobm_command

_sys_vlanVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN._1_untag_command
