Active Fabric Manager Overview

Dell’s Active Fabric Manager is a key software application to automate tasks associated with designing, building and monitoring data center fabrics, reducing fabric deployment time by up to 86% compared to manual configurations. Users can now design and deploy Layer 2 & Layer 3 fabrics within a matter of minutes. Unlike traditional Network Management tools that primarily focus on performance monitoring of various network elements, AFM has been built ground-up as an automation and orchestration tool for the entire fabric.


AFM includes many innovations that can save time and eliminate manual tasks associated with fabric design and deployment. For example, AFM includes a design wizard which simplifies the entire process of designing a network fabric, end-to-end. The wizard prompts the user to provide inputs required for the fabric design in an intuitive fashion. In the background, AFM carries out all necessary calculations to present the most appropriate fabric topology, eliminating guesswork and errors that are common in network design and implementation. The designs are derived from a set of predefined templates that have been validated for deployment as Layer 2 or Layer 3 fabrics, including spine-leaf Active Fabric topologies and underlying technologies such as Dell Virtual Link Trunking (VLT) and stacking.

 Video Presentation of AFM 1.0 by Brad Hedlund (note: this is not for the latest version of AFM)


  1. What is AFM?

    AFM is standalone software from Dell Networking that is aimed at automating the tasks associated with the deployment of datacenter fabrics. The tasks span the various stages of the fabric deployment lifecycle that includes Design, Build and Run (Monitor)

  2. Is AFM applicable only for Distributed Core deployments?

    AFM automates the design and deployment of Layer-3 Fabrics (e.g., Distributed Core) as well as resilient Layer-2 Fabrics leveraging VLT (Virtual Link Trunking)

  3. Does AFM support MXL?

    Yes. AFM supports MXL as a switching device in the supported Layer-2 topologies. AFM also automates the stacking of MXL switches across M1000e blade chassis 

  4. Does AFM support IOA?

    AFM is IOA ready.  It requires IOA with software version 9.3+. AFM includes templates supporting chassis and private VLAN settings. We will continue to add more templates in upcoming releases

  5. What are the various switches that are supported with AFM?

    The switches supported are Z9500, Z9000, S6000, S5000, S4048-ON, S3048-ON, S4810, S4820T, MXL, IOA, S60, S55, N4000, N3000, and N2000 

  6. What is the maximum number of switches supported in a particular fabric?

    This depends on the AFM design template and the oversubscription that is chosen by the user. For instance, the Layer-2 topology with 10GbE endpoints supports 2 * Z9000s (in a VLT pair) in the Spine Layer and up to 26 * S4810s (13 VLT pairs) in the leaf layer. Please refer to the AFM User’s guide for all supported topologies and the scalability limits

  7. Where can I download the AFM software from?

    AFM can be downloaded only by users who purchase the license from the Dell Digital Locker portal ( For internal usage, demo or training, you can contact the Dell Solutions Centers

  8. Does AFM require a license now?

    For now, AFM does not require a license to run. However, starting with v2.5, users have to purchase a subscription to access the Dell Digital Locker. The subscription grants users the right to download AFM binaries and updates for a finite period of time, e.g., one year. The subscription gives users access to all software upgrades and feature requests.
    Note that AFM does not expire and is not tied to the duration of the subscription. In other words, users can continue to use AFM, even if the subscription has expired

  9. How can customers buy the AFM Iicense?

    For now, AFM does not require the user to enter a physical license, such as a key. Licensing AFM to customers is enforced via the Dell Digital Locker, a new automated system for digital fulfillment. Contact your sales representative to request a quote for AFM for the established duration (currently one year)

  10. Does the AFM license have a limitation per number of users or devices?

    AFM does not currently have any limitation for the number of devices, users, time, and number of AFM instances that can be run simultaneously

  11. How does the new Dell Digital Locker portal work?

    When a sales representative places a PO to purchase AFM on behalf of a customer, s/he must enter the email of the customer who will be accessing the Dell Digital Locker portal. Upon processing and validation of the PO, an email will be automatically sent to the email address used in the order. The email will contain a link to the portal. Our system will display only the products that the customer is entitled to, and for the duration of the subscription. If the subscription is not renewed, the portal will no longer display the AFM binaries for that customer

  12. What is the license cost for AFM?

    Refer to the Quote tools for more information

  13. Is there an evaluation license?

    AFM does not currently support evaluation keys. If a customer wants to test AFM before making a decision, please contact Networking Product Management at

  14. Where can I download AFM for my own training and demos?

    Contact Networking Product Management at 

  15. How does Dell Technical Support help customers with AFM issues?

    Starting with v2.5, there is no longer ProSupport SKUs for AFM. AFM will be supported so long as the customer has ProSupport for any switch

  16. How can customers who purchased AFM ProSupport migrate to the new model?

    Contact Networking Product Management at

  17. What happens when the AFM server fails?

    AFM software operates out of the data path.  Failure of the AFM server does not impact the operations of the fabrics under management.  However, AFM server failure can be mitigated by opting for the high availability feature supported with off-the-shelf hypervisor functionality like VMware HA

  18. Is AFM embedded with Dell Network Operating System 9?

    AFM is standalone software that is packaged as a holistic virtual appliance and runs in its own virtual machine. It is not a component of Dell OS 9

  19. Does AFM support PowerConnect switches?

    Starting with AFM 2.7, N4000, N3000, and N2000 are supported in the Advanced mode. It supports the three most common topologies: stand-alone, stacked, and MLAG

  20. What operating systems are supported by AFM?

    AFM packaged and distributed as a holistic virtual appliance that includes the underlying Operating System (CentOS). The virtual appliance is OVF (Open Virtualization Format) compliant and can be deployed on any standard hypervisor. However, all of the testing has been done with VMware vSphere and VMware Workstation.   Please refer to the AFM Installation Guide for additional details

  21. Does AFM have support for Fibre Channel / FCoE / converged fabrics?

    AFM does support topologies with LAN/SAN convergence. This became available with support for the S5000

  22. What is the difference between AFM and ASM (Active System Manager)?

    AFM is targeted at the network admin and provides an automation solution to design, deploy and monitor datacenter fabrics. ASM is complementary software from Dell that automates the deployment, and management of physical and virtualized CI (converged infrastructure). ASM is primarily targeted at the CI admin

  23. Does AFM replace the commonly deployed NMS tools?

    No, AFM is complementary to NMS offerings like OpenManage Network Manager (OMNM). AFM is now able to link and launch NMS consoles, currently OMNM

  24. I heard that AFM now supports closer integration with 3rd party private cloud and virtualization environments.

    We did, through northbound API’s, AFM provided transparent fabric automation for the OpenStack Neutron plugin. However, given the complexity and variety of OpenStack deployments, this support was deprecated in AFM in favor of a new project: the Dell Networking OpenDayLight for OpenStack. This package connects the ODL controller to the Neutron component of OpenStack. Explore the more details in the Dell documentation.

    In addition, AFM has a special, stand-alone package called “CLI for the VMWare vSphere Distributed Switch (VDS)”, which allows Network administrators to retrieve vital information from VMware virtual networks

  25. How many design templates does AFM now support?

    AFM now supports over 100+ design templates. In addition, these templates are customizable to help better meet the unique requirements of our customers

  26. I understand AFM will now support existing fabric environments?

Yes, with very limited features. AFM has the ability to discover and “bolt on” to existing Dell Active Fabric deployments. The plan is to improve this feature to make it on par with green field designs

  • In the manual, there a section about installing in an existing Centos Machine via RPM. "Download the install script from iSupport. The name of the install file is AFM-INSTALLER-2.5.0.rpm."

    Well, I can't find this rpm file neither dell nor force10 support page. Where can I found this file?
