Network Interface Management Tool

This Python script provides a command-line tool for managing network interfaces and VLAN subinterfaces on a Linux system. It allows you to display available network interfaces, create VLAN subinterfaces, change IPv6 addresses on VLAN interfaces, and delete VLAN subinterfaces.

Features

• Show Interfaces: List all available network interfaces along with their IPv6 addresses.
• Create VLAN Subinterface: Create a VLAN subinterface on a base network interface and assign an IPv6 address to it.
• Change VLAN IPv6 Address: Modify the IPv6 address of an existing VLAN subinterface, with an option to delete the old address.
• Delete VLAN Subinterface: Remove a VLAN subinterface from the system.

Prerequisites

• Python 3.x
• Linux-based system
• Required utilities installed (ip, subprocess)
