DevNet Sandbox Ideas

I think it would be a good idea to be able to save your CML labs in DevNet Sandbox for a small monthly fee. I think multiple people would benefit from this and it would be a good business idea. I would love to be able to do this. Thanks ... View more

  I managed to book the DNA Lab 2, but i've issue authenticating with the DNA:   i've tried with Admin\Cisco1234! and admin\Cisco1234! without any success, those were the crendtial provided on the lab preview and the lab topology, any idea? keep telling me " Unable to log in at this moment. Please try again at a later time. ", but i'm already 1h into the lab i highly doubt that the lab didn't start fully yet!   Thanks!   ... View more

Maybe I'm missing it in the Always On sandbox, but I'd like to see some comprehensive labs related to NSO and WAE so we can practice with them. Thanks! Chris ... View more

Hi, It's really nice to have access to the APIC Sandbox (version 2.2.2) available on sandbox aicdc.cisco.com. Did you have already plan an upgrade to the latest release 3.0.x ? It would be great :-). Regards, Ju ... View more

Before creating a reservation a timezone hint would be great. Or a reminder in the tour to set the timezone in your profile. Yes, I made a reservation in the wrong timezone. User error. ... View more

Hello, I am trying to SSH to always on IOS XE devices in the DevNet sandbox with Ubuntu Linux as I try to learn Python. I receive the following error when I try and connect to any of them: tiate with 131.226.217.149 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1 I have editing the ssh_config file in /etc/ssh/ssh_config to add: KexAlgorithms diffie-hellman-group1-sha1,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1 Ciphers 3des-cbc,blowfish-cbc,aes128-cbc,aes128-ctr,aes256-ctr but I can't no matter what I do ssh_config is not editable.

It would be great to have the functionality for moderators in a space to toggle on a feature that allows non-moderators to comment to a posts thread when a space is set to announcement mode. We have a space that we only want the moderators to post in, but do want non-moderators to be able to reply to the posts with feedback or questions. Thanks! ... View more

I observed a couple of things about this lab which I think might be improved.  1) After provisioning of the sandbox leaf switches were not reachable. I assumed this is done by purpose for people to play with LAN automation part. If that's correct then having a small tutorial which mentions this would really help. 2) ISE is not integrated into DNAC. Moreover SSH credentials which are required for ISE onboarding into DNAC are not provided. So basically from 5 devices we can only work with 2. Would be good to either have ISE already integrated or keep to possibility to do it on our own.  3) There is a button to redeploy a vm from image (developer box). It is also possible to restart ISE server. Would be great if we can have some sort of reset or redeploy option for the HW switches or lab overall. The use case for this is when someone messed up the lab (like I just did unintentionally) they could have an option to reset it.   Thanks a lot for giving us opportunity to play with the new technologies.    ...

A very useful Sandbox for all developers working with Webex Cloud collaboration, is to have a sandbox with the resources required for cloud collaboration.   A simple topology that can be booked within 15 minutes but completely reliable as to practice API in a complete topology and also troubleshoot various issues.   This is a sandbox that has been missing  and as cloud collaboration is gaining its recognition, this could be useful to all. We will need (CUCM, IMP, CUC, EXPC-E, AD, 3 PCs) This would need access to Control Hub for service creation. An automation script to create a few users upon booking this lab, or a script to get the users after the lab is created. This would need access to Internet for testing but not to PSTN services.  ...

We have discovered at least two issues so far with the DevNet Beginner learning track at: https://developer.cisco.com/learning/tracks/devnet-beginner In the Network Programmability module the lab titled "Cisco DNA Center APIs with Python: Part 1 - The Basics" doesn't actually exist. This link really takes you to a lab titled "Cisco DNA Center API Overview". I'm not sure which is supposed to be the correct lab but either the link is titled incorrectly or is pointing to the wrong lab. On page 2 of the "Cisco DNA Center Platform - Authentication" lab (and continuing on through the next several labs you are asked to do some work in Python requests making calls on DNAC with thinks like requests.post(url, auth=HTTPBasicAuth(DNAC_USER, DNAC_PASSWORD)) however, these will all fail because the SSL certificate on the DNAC server is self-signed. All of these calls need to be changed to something more like requests.post(url, auth=HTTPBasicAuth(DNAC_USER, DNAC_PASSWORD), verify=False) which will ignore certificate errors. Ideally the need for this would also be explained to the learner so they understand that ignoring certificate errors in production is a bad idea. Thanks! -Ben ... View more

I was able to wait for the DNA Center Lab 1. It sims the ISE server listed in the lab is not reachable. ISE is fundamental part of the DNA architecture so it would be good if you guys can take a look on that. Thanks. ... View more

Hi Team,   I see that when I connect to vpn to access viral sandbox , I get dns server as 10.10.20.100 but that server is not able to access internet on laptop. I know due to change in internet policy you are not allowing any lab device to not access internet but this should not apply to my laptop as I will be referring internet documents when building VIRL network in lab.   May be when I connect internet , you should give me public dns and have your internal dns for lab devices?   FYI ..   I did manually change my adapter settings to point dns to 8.8.8.8 but still internet was not working. I can resolve google.com with nslookup google.com 8.8.8.8 but I cant do ping -a google.com.I am fine when I disconnect vpn. May be you have to review dns server configured for vpn clients ?   I have reservation for next 4 days. Below is URL - devnetsandbox-us-sjc.cisco.com:20108 ... View more

Hi Thank you for some great labs. After the maintenance window last weekend the DNA Center Hardware Lab 1 is no longer available. In some of the old documentation I can see there once was 3 Hardware labs. It would be great if you guys created a DNA Center Lab with some hardware again. ... View more

This is my first time connecting to the lab with CiscoAnyConnect. I was fine to establish the VPN in first time and then connected to the devices. However, due to my laptop was hang, I did the hard reboot. After the reboot, I failed to connect to VPN. The error messages were as attached.   I managed to connect back to the lab by end the lab and then did a new reserve. It seems the problem was due to my previous VPN connection was still active and the vpn system did not allow me to establish another new connection. May I have solution on this instead of re-do the reservation for same lab? Thanks. ... View more

It should be nice to have DNA Center Lab with ISE to fully build and see SD-Access from scratch. Include AD, DNS service. There is no possibility to build a demo SDA fabric with DNA-C for learning purpose in a lab environment. ... View more
