LAN is the abbreviation for local area network and in this context virtual refers to a physical object recreated and altered by additional logic. How to Draw Clear L3 Logical Network Diagrams Packet Pushers The biggest single problem I’m seeing when working on enterprise networks is the lack of L3 logical network diagrams. Most of the time I’m facing situations where a customer doesn’t have any logical network diagrams to give. L3 diagrams are vital for troubleshooting or for planning changes. Also, logical diagrams are in many cases more valuable than […] VLAN Tagging Understanding VLANs Ethernet Frames Vlan tagging. Understand IEEE 802.1q, ISL, trunk links, untagged & tagged frames, default & management vlan plus much more. Vlan Security are also covered along with implementation diagrams. networking Private VLAN configuration (With Diagram ... VLAN 1 is a standard VLAN. Basically the top switches contain hosts on VLAN 1 and a trunk to the router on a stick. The bottom switches contain hosts in VLAN 1 and VLAN 10 (the private VLAN, which VLAN 11 is the isolated VLAN). Since the trunks for all switches must pass VLAN 1 and 10 (or 11?) traffic I did not make them members of a private VLAN. What is a Network Diagram | Lucidchart A network diagram can be either physical or logical. Logical network diagrams. A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols.
