Looks like at this current time 'show ntp config' doesn't have a key in the scheme configuration yet. This is why its not working. We might see this particular command in up and coming updates to pyATS/Genie.   I hope the above helps! ... View more

Hi Eva3si0n,   If your question is "how I fix/troubleshoot a memory leak issue" than I recommend raising a TAC case about this to avoid any production issues. ... View more

Hi Al_b,   I'm able to replicate your issue when I configure an IOSXE router with the "ntp server x.x.x.x prefer" statement. You'll see below that Genie didn't even parse the command as it said "bit it returned empty" indicating its not recognizing the prefer statement. | Parsed command 'show ntp config' but it returned empty |   I've reached out to the pyATS Team to see if there is anything that can be done in the meantime. ...

Would you have much luck by nesting the telnet session within the SSH connection that NetMiko is giving you?   For example:   net_connect = Netmiko(**cisco1) command = "telnet 192.168.1.1" telnetusername = "cisco" telnetpassword = "cisco"   print() print(net_connect.find_prompt()) output = net_connect.send_command(command) output1 = net_connect.send_command(telnetusername) output2 = net_connect.send_command(telnetpassword) ...

Interesting!   Two questions: -What version of pyats/Genie are you using? -What iOS version are you using? ... View more

Hi Aniisss,   It looks like for NetA you have picked the broadcast IP address which is an unusable IP address in the /28 subnet.   If you choose a /28 for 204.15.5.0 than the following applies: -Range: 204.15.15.1 through to 204.15.15.14 -Broadcast Address: 204.15.15.15   For NetB you have picked an IP address that doesn't belong in that /27 subnet. If you used an IP address between the range of 204.15.5.33 through to 204.15.5.62 than this will work as they are usable hosts.   If you get stuck with Subnet calculations than Subnet Calculators are a quick and easy way to fix up these errors when they come up.   I hope this helps!       ...

Not a bad idea at all! The Sandboxes on the Devnet website won't actually show you VIRL because its a backend system used to emulate the various Cisco iOS platforms.   There are rack rental companies out there that you can pay to reserve an amount of time with some devices. They are typically used for Labbing. Depending on how many devices you want ect the costs can vary.   I hope this helps! ... View more

Hi Temmokan,   The NX-OS Programmability Sandbox is open and working currently. This particular sandbox is always on hence why the "Reserve" icon has been disabled. I've attached a screenshot highlighting how to connect to this particular device (note: you don't need to be on any VPN).   Below a quick output of me logging in now without any issues   =============OUTPUT====================== jonathan@X1-Carbon:~/Documents$ ssh -p 8181 admin@sbx-nxos-mgmt.cisco.com The authenticity of host '[sbx-nxos-mgmt.cisco.com]:8181 ([64.103.37.14]:8181)' can't be established.
