Q1. What is the Cisco APIC Enterprise Module (APIC-EM)?
A. With the advent of SDN driven network programmability and abstraction, IT operations management is poised for a transformation to higher levels of agility and automation. The Cisco Application Infrastructure Policy Controller (APIC) Enterprise Module platform extends Application Centric Infrastructure (ACI) to the WAN and access edge. The APIC-EM shifts conventional configuration based network management to a new policy based management paradigm, enabling new end to end IT solutions for services such as Network Security, Unified Communications, WAN Automation and Smart Troubleshooting. The controller offers customers a low-risk, evolutionary approach to adopting software-defined networking (SDN) technologies in their branch and campus environments.
Q2. Is the Cisco APIC Enterprise Module a hardware device or software application?
A. The Cisco APIC-EM GA release will be available as an ISO image download and as an APIC-EM Physical Appliance.
Q3. What equipment is required to install the Cisco APIC Enterprise Module – are there any special specs?
A. Cisco UCS is the only supported hardware in GA.
Q4. What applications will be supported in the first release of APIC-EM?
A. The Cisco APIC-EM GA Release will support the Inventory, Discovery, Topology, Path Visualization, NG-PnP and IWAN Applications.
Q5. What types of North bound APIs does the Cisco APIC Enterprise Module support to interact with the application layer, such as customer applications, services and policy engines?
A. APIC-EM supports the Representational State Transfer (REST) format to make API calls.
Q6. What all network devices does APIC-EM support?
Q13. How many nodes can the APIC-EM controller manage? A. The Cisco APIC-EM GA Release will support the following scale limits:
Network Devices (Switches, Routers, WLC): 2000
Wireless Access Points: 2000
Hosts/End points: 20000
Q14. What languages can I use to develop an application that calls the APIC-EM REST API?
A. You can use any language that provides a HTTP(S) aware library; such libraries are available for most common high-level programming languages. These libraries provide wrappers that enable you to issue REST API calls from your native programming environment, parse the result that the server returns, and make that result available in the native programming environment.
Q15. Does APIC-EM support High-Availability installations?
A. Right now, all APIC-EM controllers are resilient, which means that if a feature of the controller becomes unavailable, a new instance of that feature is instantiated automatically. Resilience is not instantaneous, so REST callers need to handle error codes and message timeouts appropriately to retry as necessary.
GA release will have support for hardware redundancy.
Q16. What’s RBAC?
A. Role-Based Access Controls
The RBAC mechanism utilizes security tokens that the controller issues upon successful authentication of a user of the APIC-EM controller. All subsequent requests from the authenticated user must provide a valid token.
Q17. Do I need a service ticket?
A. All REST requests must include service ticket as the value of the X-Auth-Token header except the request that generates a service ticket.
Hello teamI have been two days trying to implement a job and I hope someone can help me or at last tell me there is no way no do it.I have a capture configured on two Cisco (9500 ans a 9300) devices.I have made a job on Cisco Prime to launch the capture e...
Hello!I have ISR 4331, Cisco IOS XE Software, Version 16.06.07 and ASA 22.214.171.124 with RESTful API.Can I operate ASA via REST API directly from the router, for instance run a python script to change an ACL ?
I have a set of successful discoveries in DNAC. I know that the devices discovered initially will continue to be updated every 25 minutes. What I'd like though, is to have DNAC regularly run the discoveries. I set up my discovery scopes to scan subnets wh...
