Setup

Netmiko version

(Paste verbatim output from pip freeze | grep netmiko between quotes below)

n/.venv/bin/python -m pip freeze | grep netmik
netmiko==4.3.0

Netmiko device_type (if relevant to the issue)

(Paste device_type between quotes below)

device_type = 'cisco_ftd'

Steps to Reproduce the Issue

Error Traceback

(Paste the complete traceback of the exception between quotes below)

13:12:13 - ERROR - netmiko_ftd.py:37 - getPolicy -

Pattern not detected: 'packet\\-tracer\\ input\\ ACI_Prod\\ TCP\\ 10\\.184\\.32\\.247\\ 1025\\ 10\\.185\\.233\\.36\\ 5432' 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.

Relevant Python code

(Please try to essentialize your Python code to the minimum code needed to reproduce the issue) (Paste the code between the quotes below)

        self.__FW = {
            'device_type': 'cisco_ftd',
            'host': self.__HOST,
            'username': self.__USERNAME,
            'password': self.__PASSWORD,
            'port': '22',
            "session_log": "netmiko_session.log",
            'fast_cli': False
        }
        self.rule_name = ''

    def getPolicy(self,srcintf: str, protocol: str, sourceip: str, dest: str, destport: int):
        log.debug("-- Init Netmiko Connection --")
        try:
            net_connect = ConnectHandler(**self.__FW)
            srcport = 1025
            output = net_connect.send_command(f"packet-tracer input {srcintf} {protocol} {sourceip} {srcport} {dest} {destport}", read_timeout=30, expect_string=r">")
            print(f"packet-tracer input {srcintf} {protocol} {sourceip} {srcport} {dest} {destport}")
        except Exception as error:
            log.error(error)

According to the netmiko session log, it appears that the command is incomplete due to something in the terminal Can you help me?

@ktbyers have an idea for this?

Try disabling cmd_verify here:

output = net_connect.send_command(
    f"packet-tracer input {srcintf} {protocol} {sourceip} {srcport} {dest} {destport}", 
    read_timeout=30, 
    expect_string=r">",
    cmd_verify=False,
)
