Cisco APIC-EM Network Path Visualization v1

Transcription

1 Cisco APIC-EM Network Path Visualization v1 Last Updated: 04-DEC-2015 About This Solution Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) is a software-defined networking (SDN) controller designed to orchestrate and manage local-area networks (LANs) and wide-area networks (WANs) composed of Cisco infrastructure. The APIC-EM solution is made up of four applications: Network PnP, IWAN, Path Trace, and Network Inventory. All of these applications can be exposed either from the GUI or a RESTful API. The APIC-EM Controller s Path Visualization application greatly eases and accelerates the task of connection troubleshooting by allowing you to verify the path a flow would take through the network. Path trace allows you to also check if an ACL would block the traffic through the network. This demonstration does not explore the APIC-EM API capabilities. For information on APIs, see the Cisco APIC-EM Network Python Sandbox v1.1. About This Demonstration This demonstration includes scenarios showing you how to use Cisco APIC-EM Path Visualization, including: Scenario 1: Cisco APIC Enterprise Module Overview Scenario 2: Cisco APIC Enterprise Module Path Trace Requirements This demonstration does not require an endpoint router.

2 Topology This content includes preconfigured users and components to illustrate the scripted scenarios and features of the solution. Most components are fully configurable with predefined administrative user accounts. You can see the IP address and user account credentials to use to access a component by clicking the component icon in the Topology menu of your active session and in the scenario steps that require their use.
