@ktbyers kindly help

@larby22 Try this:

# code above here is the same...
net_connect = ConnectHandler(**CiscoASR)
net_connect.ansi_escape_codes = True
output = net_connect.send_command('show version')
print output
print '-' * 80
print repr(output)

@ktbyers thanks for checking see output below. It's still not displaying any output.

from netmiko import ConnectHandler import netmiko CiscoASR = { ... 'device_type': 'cisco_xr', ... 'ip': '192.168.x.x', ... 'username': 'verify', ... 'password': 'verify', ... 'port': 22, ...

What does the actual show version look like when you do it manually?

@larby22 Can you turn on logging and find what you see.

I suspect the prompt is getting messed up because of ANSI escape codes which is causing Netmiko to not properly find the command output.

[larby22]

Thanks @ktbyers I am quit new to netmiko . Kindly help point me to how i can enable logging. Thanks in advance

[ktbyers]

@larby22 My bad...I forgot to include the link of how to enable logging earlier...

Hello @ktbyers , Kindly find attached debug output. The debug output displays the expected output in the log but not on the terminal. Debug_log_netmiko.txt

larby@ubuntu:~$ sudo python pecheck3.py

I am going to delete all of the PanOS comments from this issue (as two separate possible issues are getting conflated together and it is confusing).

[ktbyers]

@larby22 The commands there weren't show version? I thought you weere executing show version.

[larby22]

Hi @ktbyers sorry for the mix up. I have attached the log output for "show version" .

Also kindly find below output on the terminal

from netmiko import ConnectHandler import netmiko import logging

logging.basicConfig(filename='test.log',level=logging.DEBUG) logger = logging.getLogger("netmiko")

CiscoASR = { ... 'device_type': 'cisco_xr', ... 'ip': '192.168.2.1', ... 'username': 'verify', ... 'password': 'verify', ... 'port': 22, ... 'verbose': False, ... } net_connect = ConnectHandler(**CiscoASR) net_connect.ansi_escape_codes = True output = net_connect.send_command('show version') print output 0/CPU0:MY_PE_ASR9K_01#show version

Do you have timestamps turned on (for this device)? If so I would probably turn those off.

@larby22

Hi guys. @larby22 @ktbyers

Did you figure this out? I've got the same issue. No output in netmiko send_command.

Here is my script:

from netmiko import ConnectHandler
cli = ConnectHandler(   device_type='cisco_ios_telnet',
                        ip='10.0.20.1',
                        username ='cisco',
                        password= 'cisco',
                        secret= 'cisco')

cli.enable()
cli.ansi_escape_codes = True
result = cli.send_command('show ip int br')
print(result)

output is empty.

@artyomovs Are you using Netmiko 3.0.0? It just recently came out. If not, can you re-test with Netmiko 3.0.0.

Thanks, Kirk
