Switch Configuration Retrieval Script

Description

This Python script retrieves and saves the running configurations from a list of network switches/routers. It supports multiple vendors and can handle both SSH and Telnet connections. The script uses Netmiko for network device connections and logging for verbose output.

Features

• Automatically detects device types for SSH connections using Netmiko's autodetect feature.
• Supports multiple network device vendors (Cisco, Juniper, Arista, Dell, HP, Huawei, Brocade, Extreme Networks).
• Attempts SSH connection first and falls back to Telnet if SSH fails.
• Logs detailed output to both the console and a log file (log.txt).
• Saves configurations to individual files named <ip>_config.txt in the configs directory.

Requirements

• Python 3.x
• Netmiko library

Installation

1. Clone the repository:

   git clone <repository_url>
   cd <repository_directory>

2. Install the required Python packages:

   pip install -r requirements.txt

Usage

Command Line Arguments

• -i, --ip: Single IP address or multiple IP addresses separated by commas.
• -f, --file: File containing a list of IP addresses (one per line).

Examples

1. Retrieve configuration from a single IP address:

   python script.py --ip 192.168.1.1

2. Retrieve configurations from multiple IP addresses:

   python script.py --ip 192.168.1.1,192.168.1.2

3. Retrieve configurations from a file containing IP addresses:

   python script.py --file ip_list.txt

Script Execution

1. Run the script with the appropriate arguments:

   python script.py --ip 192.168.1.1

2. Input the required credentials when prompted:

   • Username
   • Password
   • Enable Password (if required)

Example Usage

python script.py --ip 192.168.1.1,192.168.1.2

python script.py --file ip_list.txt

Logging

The script logs detailed output to both the console and a log.txt file. The log file includes timestamps, log levels, and messages.

Supported Vendors and Commands

The script supports multiple network device vendors and their respective commands for retrieving running configurations. The COMMANDS dictionary maps device types to their commands.

COMMANDS = {
    'cisco_ios': 'show running-config',
    'cisco_nxos': 'show running-config',
    'arista_eos': 'show running-config',
    'juniper_junos': 'show configuration',
    'dell_os10': 'show running-configuration',
    'hp_procurve': 'show running-config',
    'huawei': 'display current-configuration',
    'brocade_fos': 'configshow',
    'extreme_exos': 'show config',
}
