Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Prerequisites for Configuring Layer 2 Networks

Layer 2 Prerequisites

Before you begin to perform the tasks in this guide, complete the following:

  • Install the ACI fabric and ensure that the APIC controllers are online, and the APIC cluster is formed and healthy—For more information, see Cisco APIC Getting Started Guide, Release 2.x.

  • Create fabric administrator accounts for the administrators that will configure Layer 2 networks—For instructions, see the User Access, Authentication, and Accounting and Management chapters in Cisco APIC Basic Configuration Guide.

  • Install and register the target leaf switches in the ACI fabric—For more information, see Cisco APIC Getting Started Guide, Release 2.x.

    For information about installing and registering virtual switches, see Cisco ACI Virtualization Guide.

  • Configure the tenants, VRFs, and EPGs (with application profiles and contracts) that will consume the Layer 2 networks—For instructions, see the Basic User Tenant Configuration chapter in Cisco APIC Basic Configuration Guide.


Caution

If you install 1 Gigabit Ethernet (GE) or 10GE links between the leaf and spine switches in the fabric, there is risk of packets being dropped instead of forwarded, because of inadequate bandwidth. To avoid the risk, use 40GE or 100GE links between the leaf and spine switches.
