Hybrid tools

These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams. Typical capabilities include but not limited to: * Displaying port / interface information on connections between devices on the maps * Visualizing
VLAN A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2).IEEE 802.1Q-2011, ''1.4 VLAN aims and benefits'' In this context, virtual, refers to a physi ...

subnet A subnetwork or subnet is a logical subdivision of an IP network. Updated by RFC 6918. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to the same subnet are addressed with an identical ...

Drawing tools

These tools help users to create network topology diagrams by adding icons to a canvas and using lines and connectors to draw linkages between nodes. This category of tools is similar to general drawing and paint tools. Typical capabilities include but not limited to: * Libraries of icons for devices * Ability to add shapes and annotations to maps * Ability to create free-form diagrams
