Hi, Hopefully simple question. I'm doing the "Cisco DNA Center Platform - Network Devices" lab. It uses the always on DNAC instance at https://sandboxdnac.cisco.com. The lab shows some API calls that look like a holdover from APIC-EM, to list network devices and a subset of those devices by IP/MAC address. IE, not intent-based API calls. Anyway, I wanted to find the API doc for the API calls in the lab, and it took some looking around. I found them in the API doc of the always-on DNAC instance only in the API version 1.0 and 1.1. All the API doc details for API version 1.2.x (several listed) do not list the API alls in the lab, but instead list only the intent APIs. However, the two always-on instances (running 1.2.6 and 1.2.10) do accept the API calls that aren't listed in the 1.2.x API docs. So my question is one of documentation and convention. Should we be looking at every version of the DNAC API doc for find all supported API calls for DNAC? Is there a better source for DNAC API documentation that is comprehensive? I'd like to get a thorough idea of what's possible with the DNAC API, so any pointers in how to navigate the API doc would be appreciated. Thanks!

Hi Adam, Thanks - yes, those are the slides that I couldn't recall. I find the drawings of the API branch relationships useful. I listen to the Cisco Live on Demand recording of the session when I catch a spare moment! APIC-EM API Deep Dive (2017 Berlin) Also, I'm good with a use case approach as well. I was thinking more in terms of a flow like "do a, b, c with an app in the GUI, then where do I look in the API for the equivalent" kind of approach. The deep dive session will help. Maybe I'll add the CLUS 2017 session to my schedule! :-) Thanks again, Wendell

Hi, I'm attempting to connect the dots a bit on three primary ways to think about what you can do with APIC-EM. I seem to recall some slides that spell out some of these ideas, but I can't find them - if that rings a bell with anyone, would love to hear of a link. Anyway, my question/request is for any help in completing and making the following breakdown complete and accurate. The idea is pretty basic: - The API has several branches or services (see APIC doc here http://devnetapic.cisco.com/). - The APIC-EM doc of course lists the APIC-EM apps by name - The APIC-EM GUI lists the main functions as clickable icons on the left side of the page. Big picture: What's the correlation between those three? Which main branch(es) of the API tree go with which apps and go with which main function on the far left of the GUI (the application pane, I believe it's called)? Here's what I've come up with so far, ignoring the parts of the API that seem like overhead topics (aka not related to a specific app): API - Flow Analysis; App - Path Trace; GUI – Path Trace API – Inventory; App - Network Visibility; GUI – (1) Discovery, (2) Device Inventory, (3) Host Inventory API - Network Discovery; App - Network Visibility; GUI – not sure API - Network Plug and Play; App – Network Plug and Play; GUI – Network Plug and Play API - Policy Administration; App – EasyQoS; GUI – EasyQoS API – Topology; App - Network Visibility; GUI – Topology API – Visibility; App – IWAN; GUI - IWAN I know there are probably more than a few exceptions and possibly some overlap. Any input is welcome.

Hey Adam, Thanks! So, sounds like I shouldn't waste my time trying to boot it on a server w/ 16G? (Just a curiosity). But in all seriousness, the goal is so much what's needed for full support (I agree, the current install docs say 12 cores recommended). It's more what's needed to get it working in a home lab that's likely not more than dozens of network devices. Maybe spend to get 32G (at least) and an SSD, but possibly save money on the number of cores? That's consistent with my experience so far. Thanks, Wendell

Hi Yawchen! Yep, I see that 200 MBs requirement in the install docs, and it makes me wonder what led to that particular line item. Maybe we'll learn more. Looks like SATA I, II, III, only SATA I is too slow by spec at least. I'm pretty sure the disks on the server I'm using are SATA I (150MBs). Wendell

Hi all, I am hoping to find out what some of you have used for your APIC-EM server in your home lab. My goal is to figure out how much hardware someone might need to purchase to run APIC-EM bare-metal. (I would likely run it under ESXi, but the bare-metal comparison can be a little more straightforward.) But I'll take input on bare-metal or on ESXi, either way. Anyone out there that is willing to share, I’d love to hear! In particular, what specific CPU and RAM. Also, if you were doing anything that you thought might stress APIC-EM (volumes of API calls? Discovering large networks with large IP address ranges?) would be good to know. I’ve run it on a 4-core CPU in lab with no problem (install docs say minimum of 6 cores), but I’ve not stressed APIC-EM to any large degree. Hoping to generate an ongoing conversation here. In case it helps: APIC-EM doc page (with current install requirements): http://www.cisco.com/c/en/us/support/cloud-systems-management/one-enterprise-network-controller/tsd-products-support-series-home.html Intel processor page: https://ark.intel.com Just to get it rolling, so far I’ve used the following: Generic Rack mount server with: Intel E3-1220V2 processor 32G RAM 500G HDD 6 x 1Gbps Ethernet bare-metal install Mostly doing API calls, QoS, discovery of small (10 device) networks, nothing high-volume Thanks, Wendell

Hey Vince, Looks like some great introductory learning material. Can you give a little more context, like: are they available to use now? If so, can you add some links? (Couldn't find them on DevNet.) (or are these coming soon to an event...) Also, you mention another post " Additional Background for DevNet1040, 1041 and 1042 seminars " - couldn't find that with a search. Add a link there as well? Thanks. At your convenience.

Any chance you might post the schedule for the DevNet Springboard Event by May 16th? That's the 100% refund date on the Sunday techtorials, so it'd be nice to see the details of your event to then choose whether to cancel a tectorial to attend. Thanks.

Hi Brett, Thanks for the help. I believe the mistake is mine - I translated "DevNet Sandbox" in cmreed's original post into "developer.cisco.com", which is incorrect; I do have access problems for the APIC EM content there. However, I didn't look at the correct URL - looks like https://developer.cisco.com/site/devnet/sandbox/ gets you to at least one page on the DevNet sandbox. From there, I can get to the APIC EM lab. Sorry for the mistake, and thanks for the help. Wendell

After clicking to get APIC EM from the developer.cisco.com page, the next page shows "We could not find the requested page on DevNet". I've seen this error myself, and seen other posts here in the community, when trying to download newer versions of the all--in-one VM. Any idea as to whether it's too early to get APIC-EM, or if there's a web feed problem, or something else? Thanks.

Hey Jerry, Thanks for the scoop. The link worked. (The web page still doesn't - but short-term problem is solved.) Thanks much! Wendell

Hi folks, Simple support question. I tried from developer.cisco.com two links: one to download the AIO VM, one to see the ONE tutorial (on the line above). Both result in a new page with a "Page not found". I have downloaded the AIO VM successfully in the past, same login and computer, maybe 2 weeks ago. (FYI, I was thinking there was a new AIO VM for the new SDK version...) I tried two browsers, three different computers, even tried from the coffee shop so as to use a different DNS server, same results. It's been happening since Monday the 8th. I have clicked around other links on the developer.cisco.com page, and get to other content. Any ideas? Thanks, Wendell
