Things you might try to fix this:
1. Explicitly set your pattern using the expect_string argument.
2. Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information

That is not "ios_xr" i.e. your device_type is wrong.

Also disabling of output paging is not working and there are ANSI escape codes are in the output?

It is a bit unclear what the actual operating system of the catalyst 1300 is? You can try "cisco_ios", but you will need to figure out why terminal length 0 is not working.

Also you probably need to disable the output paging, from looking at the CLI manual for Cat 1300, it looks like `Example The following example dumps all output immediately after entering a show command.

terminal datadump

Also need to set:

net_connect.ansi_escape_codes = True

So your code should become:

from netmiko import ConnectHandler
import logging
logging.basicConfig(filename="test.log", level=logging.DEBUG)
logger = logging.getLogger("netmiko")
net_connect = ConnectHandler(
    host="192.168.10.1", 
    username="username", 
    password="password", 
    device_type="cisco_ios",   # Note change
    secret="", port=22,
)

net_connect.send_command("terminal datadump", expect_string=r"#")
net_connect.ansi_escape_codes = True

# Then try your "show" command using the "send_command" method.

Let me know if this works and we can build a driver for this platform.

Of course I would like you to create a driver for this platform, just tell me what I can help with.

Code: 

from netmiko import ConnectHandler
import logging
logging.basicConfig(filename="test.log", level=logging.DEBUG)
logger = logging.getLogger("netmiko")
net_connect = ConnectHandler(host="192.168.10.1", username="username", password="password", device_type="cisco_ios", secret="", port=22, )
net_connect.send_command("terminal datadump", expect_string=r"#")
net_connect.ansi_escape_codes = True
net_connect.send_command("show ver")
net_connect.send_command("show interface status")
net_connect.disconnect()

Result

>>> net_connect.disconnect()
>>> net_connect = ConnectHandler(host="192.168.10.1", username="networkmanager", password="N@Man390erp", device_type="cisco_ios", secret="", port=22, )

That doesn't work either

from netmiko import ConnectHandler
import logging
logging.basicConfig(filename="test.log", level=logging.DEBUG)
logger = logging.getLogger("netmiko")
net_connect = ConnectHandler(host="192.168.10.1", username="networkmanager", password="N@Man390erp", device_type="cisco_ios", secret="", port=22, )
net_connect.send_command("terminal datadump", expect_string=r"#")
net_connect.ansi_escape_codes = True

net_connect.send_config_set('int gi1/0/3,no shutdown')

net_connect.disconnect()

Result

netmiko.exceptions.ReadTimeout: 

Pattern not detected: '\x1b\\[KciscoS1.*' in output.

Things you might try to fix this:
1. Adjust the regex pattern to better identify the terminating string. Note, in
many situations the pattern is automatically based on the network device's prompt.
2. Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information.

TextFSM likely won't wors as Catalyst 1300 is not really IOS so parsing will fail.

ktbyers commented 1 month ago

This is not valid syntactically:

 net_connect.send_config_set('int gi1/0/3,no shutdown')

You need to provide a list of commands i.e.

cmds = ['int gi1/0/3', 'no shutdown']
net_connect.send_config_set(cmds)
