Aruba CX VSF 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 Aruba CX switches that support stacking:
Switch Platform |

Aruba CX Switch Stacking Functions Supported in Aruba Central
Aruba Central supports only a few functions related to Aruba CX switch stack, such as onboarding a stack to Aruba Central and replacing member switches having the same model and part number. All other stacking related activities, such as creating a stack, deleting or adding a new member to the stack, must be performed offline, that is, outside Aruba Central.
Following stack related functions are supported on Aruba Central:
|
The Aruba CX switch stack must be setup using the CLI or the Aruba CX mobile application before onboarding on to Aruba Central. |
Onboarding a VSF stack to Aruba Central
Replacing a VSF member with same model and part number
Rebooting a member—Commander, standby, and other members
Splitting or merging a stack
VSF switchover
Aruba CX Switch Stacking Functions Not Supported in Aruba Central
Following stack related functions are not supported on Aruba Central and must be performed outside Aruba Central, after taking the stack offline from Aruba Central:
Setting up an Aruba CX switch stack
Adding a new member to an existing stack
Adding a new VSF link
Deleting a member from the VSF stack
Reassigning standby or other members to the stack
For information on these configurations, see the ArubaOS-CX Virtual Switching Framework (VSF) Guide for the respective switch series and the ArubaOS-CX VSF Best Practices document.
General Recommendations
Following are the general recommendations to note when configuring an Aruba CX switch stack:
To maximize available VSF link bandwidth, use Aruba 50G DAC cables for VSF links.
All VSF link ports in a stack must operate at the same speed (10G, 25G, or 50G).
For maximum stack resiliency, the primary and secondary members should be the same switch models with redundant power supplies connected to different circuits. This is required to minimize the probability that a single-source power failure will disable both the stack commander and standby.
A secondary member must always be defined to assume the VSF standby role.
The out-of-bandBand refers to a specified range of frequencies of electromagnetic radiation. management (OOBM) ports on the primary and secondary members must be connected to each other, either directly or through a dedicated management network. This is required to utilize the VSF split detection, which must always be enabled.
