How to create DHCP server and a policy in the Fortigate

-
Here is an example script that demonstrates how to use the  fortigate-api  package to create a DHCP server and a policy in the Fortigate   from fortigate_api import FortigateAPI # Create a FortigateAPI object fgt = FortigateAPI(host="host", username="username", password="password") # Create a DHCP server data = {     "default-gateway": "192.168.255.1",     "netmask": "255.255.255.0",     "interface": "vlan.123",     "ip-range": [         {"start-ip": "192.168.255.2", "end-ip": "192.168.255.254",}     ], } fgt.dhcp_server.create(data) # Create a policy in the Fortigate data = dict(     name="POLICY",     status="enable",     action="accept",     srcintf=[{"name": "any"}],     dstintf=[{"name": "any"}],     srcaddr=[{"name": "all"}],     dstaddr=[{"name&quo

What is Network Automation

-

The process of automating the configuration, management, testing, deployment, and operation of physical and virtual devices within a network is known as network automation. The availability of network services increases as routine network operations and functions are automated and repetitive processes are regulated and handled automatically. Network automation can be used with any kind of network. Network automation can be implemented by data centers, service providers, and businesses to increase productivity, decrease human error, and cut operational costs. Advantages of Network Automation Why Automate Our Network? The rising cost of IT for network operations is one of the greatest problems facing network managers. Manual procedures are all but impossible when data and device growth begin to overtake IT capabilities. However, up to 95% of network changes are carried out manually, leading to operational expenses that are two to three times higher than the network's purchase price.

Implementing the OSI Model in Legacy Networks: Challenges and Solutions

OSI Model 7 Layer   The OSI (Open Systems Interconnection) model is a conceptual framework used to standardize communication between different computer systems. It was created by the International Organization for Standardization (ISO) in 1984 and has since become the de facto standard for networking. The OSI model is comprised of seven layers, each with its own set of protocols and functions that enable the exchange of data between systems. These layers are designed to work together to provide a complete and efficient communication system. Layer 1: Physical Layer The physical layer is the first layer of the OSI model and deals with the physical transmission of data. This includes the physical medium over which the data is transmitted, such as copper wires, optical fibers, or wireless signals. It also includes the electrical signals that are used to represent the data on the physical medium. Layer 2: Data Link Layer The data link layer is responsible for the reliable transmission of da
