How to Use Virtual Network Manager: A Comprehensive Guide227

Virtual Network Manager (VNM) is a networking management tool that allows you to create, manage, and monitor virtual networks. It provides a centralized interface for managing all aspects of your network, including subnets, IP addresses, firewall rules, and routing tables. VNM can be used to manage both private and public clouds, and it supports a variety of virtualization platforms, including VMware, Hyper-V, and OpenStack.

Getting Started with VNM

To get started with VNM, you will need to install the VNM software on a server that meets the system requirements. Once the software is installed, you can open the VNM console and begin creating your first virtual network.

Creating a Virtual Network

To create a virtual network, click on the "Create Virtual Network" button in the VNM console. You will then need to specify the following information:* Name: The name of the virtual network.
* CIDR Block: The CIDR block for the virtual network.
* Subnet Mask: The subnet mask for the virtual network.
* Gateway Address: The gateway address for the virtual network.
* DNS Servers: The DNS servers for the virtual network.

Once you have entered all of the required information, click on the "Create" button to create the virtual network.

Managing Subnets

Subnets are used to divide a virtual network into smaller segments. This can be useful for organizing your network and for managing security. To create a subnet, click on the "Create Subnet" button in the VNM console. You will then need to specify the following information:* Name: The name of the subnet.
* CIDR Block: The CIDR block for the subnet.
* Virtual Network: The virtual network that the subnet belongs to.

Once you have entered all of the required information, click on the "Create" button to create the subnet.

Managing IP Addresses

IP addresses are used to identify devices on a network. VNM allows you to manage IP addresses for both private and public clouds. To create an IP address, click on the "Create IP Address" button in the VNM console. You will then need to specify the following information:* Name: The name of the IP address.
* IP Address: The IP address.
* Subnet: The subnet that the IP address belongs to.

Once you have entered all of the required information, click on the "Create" button to create the IP address.

Managing Firewall Rules

Firewall rules are used to control traffic on a network. VNM allows you to create firewall rules for both inbound and outbound traffic. To create a firewall rule, click on the "Create Firewall Rule" button in the VNM console. You will then need to specify the following information:* Name: The name of the firewall rule.
* Action: The action to take when the rule is matched.
* Source: The source IP address or range.
* Destination: The destination IP address or range.
* Port: The port or range of ports to match.

Once you have entered all of the required information, click on the "Create" button to create the firewall rule.

Managing Routing Tables

Routing tables are used to control how traffic is routed on a network. VNM allows you to create routing tables for both private and public clouds. To create a routing table, click on the "Create Routing Table" button in the VNM console. You will then need to specify the following information:* Name: The name of the routing table.
* Virtual Network: The virtual network that the routing table belongs to.

Once you have entered all of the required information, click on the "Create" button to create the routing table.

Conclusion

VNM is a powerful network management tool that can help you to create, manage, and monitor your virtual networks. It provides a centralized interface for managing all aspects of your network, including subnets, IP addresses, firewall rules, and routing tables. VNM can be used to manage both private and public clouds, and it supports a variety of virtualization platforms.
