Chapter 1. Verified Scalability for Cisco Dynamic Fabric Automation

This chapter contains the following sections:

- Overview of Verified Scalability

- Verified Scalability for a Cisco DFA Fabric

- Verified Scalability for Cisco DFA Leaf Switch

- Verified Scalability for Cisco DFA Border Leaf Switch

Overview of Verified Scalability

This document lists the Cisco verified scalability limits for a Cisco Dynamic Fabric Automation (DFA) deployment.

In the following tables, the Verified Topology column lists the verified scaling capabilities with all listed features enabled at the same time. The numbers listed here exceed those used by most customers in their topologies. The scale numbers listed here are not the maximum verified values if each feature is viewed in isolation.

The Verified Maximum column lists the maximum scale capability tested for the corresponding feature individually. This number is the absolute maximum currently supported by the Cisco NX-OS release software for the corresponding feature. If the hardware is capable of a higher scale, future software releases might increase this verified maximum limit.

Italic

Italic text indicates arguments for which the user supplies the values.

[x]

Square brackets enclose an optional element (keyword or argument).

[x | y]

Square brackets enclosing keywords or arguments separated by a vertical bar indicate an optional choice.

{x | y}

Braces enclosing keywords or arguments separated by a vertical bar indicate a required choice.

[x {y | z}]

Nested set of square brackets or braces indicate optional or required choices within optional or required elements. Braces and a vertical bar within square brackets indicate a required choice within an optional element.

variable

Indicates a variable for which you supply values, in context where italics cannot be used.

string

A nonquoted set of characters. Do not use quotation marks around the string or the string will include the quotation marks.
