ios-xe-mgmt.cisco.com lab erorr

yangcharlie — Fri, 27 Dec 2019 19:02:57 GMT

Hello, All,

I have been working on a couple of Devnet Lab, and found not request responses from ios-xe-mgmt.cisco.com

in all the labs neither Postman nor Python requests.

Below is an example when I am working on "Exploring IOS XE YANG Data Models with RESTCONF"

1, I was able to open Sandbox, but no any elements showed in SanDbox ENVIRONMENT

the IOS XE on CSR Recommended Code Always-On Sandbox.

2, updated environment on Postman with new parameters and no response from sandbox,

please see attached pics.

thanks

Hello,

Thanks for your message. By following module "Exploring IOS XE YANG Data Models with NETCONF“step 1
I am still seeing a similar issue as what I reported, log as below

(venv) devnet@devnet-virtual-machine:~/dnav3-code/intro-mdp/netconf$ python -i get_interface_list.py
Opening NETCONF Connection to ios-xe-mgmt.cisco.com
Exception: Error reading SSH protocol banner
Traceback (most recent call last):
File "/home/devnet/dnav3-code/venv/lib/python3.6/site-packages/paramiko/transport.py", line 2211, in _check_banner

File "/home/devnet/dnav3-code/venv/lib/python3.6/site-packages/paramiko/packet.py", line 622, in _read_timeout

socket.timeout

for both SSH took very long time to wait for output ( 5 + minutes), I cancelled.
(venv) devnet@devnet-virtual-machine:~/dnav3-code/intro-mdp/netconf$ ssh -oHostKeyAlgorithms=+ssh-dss developer@ios-xe-mgmt.cisco.com -p 10000 -s netconf

(venv) devnet@devnet-virtual-machine:~/dnav3-code/intro-mdp/netconf$ ssh developer@ios-xe-mgmt.cisco.com -p 10000 -s netconf
^C

Please advise.

Thanks

Thank for your reply. Here is a screenshot to access IOS-XE from my laptop.

Hello,

I searched online and found 2 sandboxes for IOS XE, which are

https://devnetsandbox.cisco.com/RM/Diagram/Index/27d9747a-db48-4565-8d44-df318fce37ad?diagramType=Topology

https://devnetsandbox.cisco.com/RM/Diagram/Index/38ded1f0-16ce-43f2-8df5-43a40ebf752e?diagramType=Topology

even both of them are 'always on' and VPNless, however, I was not able to query through my laptop. For device perspective, I do not see any device in sandboxes.

Only seeing the device in a reservable Sandbox

https://devnetsandbox.cisco.com/RM/Diagram/Index/cae403c2-27af-4c7d-b1e1-99b7d42f1504?diagramType=Topology

Really confused.

Thanks

The 2 "AlwaysOn" sandbox hosts CSR1000v with different firmware version, and you can find access details in the left "Instruction" panel.

Hello,

That's something confused me, I do not see any device on IOS XE "alway on" sandboxes according to the url provided.

I can access sandboxes without a problem, however, no SSH via netconf at all.

Thanks

You can use the folllowing links

https://devnetsandbox.cisco.com/RM/Diagram/Index/38ded1f0-16ce-43f2-8df5-43a40ebf752e?diagramType=Topology

https://devnetsandbox.cisco.com/RM/Diagram/Index/27d9747a-db48-4565-8d44-df318fce37ad?diagramType=Topology

Access to one of these would be as follows

If you cannot access these devices, please check your outbound firewall for the ports listed per sandbox (such as 8181 for ssh).

Hope this helps

Hello, All,

I am so sorry to waste your time on this bug.

What I found that my network policy blocked the ssh access to the sandbox, after moved to another laptop with a different connection, all work now.

Thanks

I had the exact same error, all i had to do is disable SSL certificate verification under Postman settings.

just an FYI if anybody else run into this.

Re: ios-xe-mgmt.cisco.com lab erorr

mocrodri — Sun, 21 Jun 2020 07:09:10 GMT

In Postman I got 'Error: self signed certificate' when I click on 'send' button.

Disabling the SSL certificate in Posman helped.
To disable it:
File > Setting > General
Look for 'SSL certificate validation' and then turn it off.

Thanks,

I can't access any SSH or any device. Note that I'm still new to sandbox.

Can I ask you to share a screenshot.
For me I checked your link and I'm getting the same as I shared in the previous screenshot I attached earlier.

Re: ios-xe-mgmt.cisco.com lab erorr

bigevilbeard — Thu, 30 Jul 2020 14:09:26 GMT

Clicking on the tile in the sandbox will yield no results. To access the sandbox an ssh client is required to connect to the device. Using Mac/Linux directly use the OS native SSH client, or Window using an SSH client such as PuTTY.

Hope this helps.

The link below is part of DevNet training section 2 on APIs. [REST APIs Part 1: HTTP is for more than Web Browsing ]
When I click the link below to go to the Sandbox, I also get an error [ Sandbox Lab not found ] .
Is this a temporary error, or is there a new link and the one below needs updating, or something else ?
