Feb 16, 2008 - hey guys anyone have or know where to get a layer 3 switch shape for microsoft Visio? Looking around on google for while now.
In this article, I will do a walk-through of a logical network diagram. As I also said in the article: I prefer to use the term “logical” instead of “L3” because it is more easily understood by somebody unfamiliar with the OSI model. It also removes the assumption (made by many non-technical people) that “L1” and “L3” diagrams are incomplete without a “L2” diagram. So I just call them “Physical” and “Logical” to avoid the confusion.You can download this article’s template file using the link to the right. Logical Diagram StencilsStencils in a logical diagram should be, obviously, logical representations of the network nodes.

Keeping that in mind, I propose that it doesn’t make sense to use a physical network device stencil, which is essentially a picture of the actual device (with ports, fans, rack ears), in a logical diagram. I prefer, instead, to use generic icons which represent different types on network devices in a network.My favorite resource for generic topology icons is Cisco. You can download a library or visit the. I am also including the most common icons in the template linked at the top of the page. SubnetsSubnets are the cornerstone of a logical network diagram.
They represent an IP network where nodes can hold L3 addresses and communicate via IP.There are three important pieces of information to hold in a subnet object: VLAN Name, VLAN ID, and assigned IP block in CIDR format. The VLAN name and ID information assume that the subnet is contained within a VLAN on a switch. When this is not the case (like with a point-to-point link between two routers), omit the VLAN ID and name and include only the subnet.
These different pieces of information are distinguished on the subnet with different font types. ConnectorsConnectors in a logical diagram connect a device to a subnet and represent a layer-3 (or sometimes layer-2) presence on the subnet. There is no need in this diagram for different colored connectors, so always use a solid black pattern. The exception to this rule is non-routable subnets (like heartbeat or vMotion), where the VLAN exists on a switch, but the switch has no layer-3 presence; in this case, use a dot or dash patterned connector.Each connector is labeled with its IP information specific to that VLAN.
Hey John, me again. I get it (as this is how it goes mostly) but I find your choice of icons frustrating. The Cisco icons are 3D (mostly) and have a 180 degree perspective, the Visio network ‘pipe’ one a 90 degree perspective. Then the Visio cloud one has a 0 degree perspective and the other Cisco ones have a 135 degree perspective. This does not make for an easy to consume diagram IFAIAK.I appreciate you are describing a high degree of detail and you’ve put much thought into this but visually, I find it pretty messy and ultimately, rather ugly to the eye. Your consideration and method are flawless but for this.
I agree buddy. The Cisco icons and the subnet stencils have a sort of “depth” to them.
Although it is difficult to show depth on a cylindrical pipe. And the clouds have none.There is a pretty limited selection on these types of icons. There have been some fancy ones made for VMWare, but I don’t believe they have all the networking related icons needed in a network diagram.If you come across a better set of stencils that have everything needed and are somewhat matching, please let me know. I’d love to improve on my current stencil set.
