As previously said, each vendor has implemented its own solution to collect, change, distribute configurations and system updates. Big vendors such as Cisco Systems, Juniper Networks, Huawei, etc. provide different suites that range from solutions for simple local area networks (LANs), to internet provider scale solutions. The so called Network Management Systems [34] simplify the management of the administered network offering centralized solutions that allow one to perform device discovery, monitoring and management, network performance analysis, intelligent notifications, and customizable alerts. To interact with devices, they build on standard protocols such as SNMP or syslog, but often use also custom solutions based on Command Line Interfaces (CLI) that can be reached via SSH or telnet (deprecated for security reasons). For instance, the Cisco Configuration Professional is a Graphical User Interface (GUI)‐based device management tool for Cisco access routers. This tool simplifies routing, firewall, Intrusion Prevention System (IPS), VPN, unified communications, wide area network (WAN) and LAN configurations through GUI‐based easy‐to‐use wizards.
