It provides functions like PoE, port security, VLAN assignment, and LLDP. This encompasses the ports that the users actually connect to. Starting from the bottom of the diagram, the Access layer is the most high density layer in terms of ports and units. The flow chart representing this network design concept is shown below: These three represent units that all have similar functions and work together to achieve the same goals while providing the necessary separation and hierarchy that help troubleshoot the network anytime issues arise. By properly grouping units that perform the same functions and creating a simple network hierarchy no matter the amount of units within it, a network can be set up to remain healthy, efficient, and will be much more easily to troubleshoot when problems occur.ĪDTRAN recommends that a network be set up with three major layers: The core layer, the distribution layer, and the access layer. In the same manner that a network administrator should view and troubleshoot a network using a top-down method like the OSI model, a successful network design should follow the same concept.

Layer 3 Switch: Switches that have full routing capabilities including routing protocols and VRRP. This includes and NetVanta 1200 series unit on R10.8.0 or higher NetVanta 1530 series units. Layer 3 Lite Switch: Switches that have limited Layer 3 capabilities not including routing protocols and VRRP. This also includes switches that are layer 3 capable, but have been deployed as a layer 2 switch (This means that no end-units are using the switch as a gateway and routing is disabled). Layer 2 Switch: Switches that do not have any Layer 3 capabilities aside from Management. To discern which type of switch you are deploying based on its NetVanta Series and features available, use the : Redundancy and Spanning-tree Configurationīefore using this document, it is important to understand the different switches that are being referenced and the different configurations that are being referenced.Physical Setup Recommendations and Documentation.Types of Switches Referenced in this Document Following these guidelines will help ensure that your network functions to the best of its abilities. While this document applies to any switch network and can be implemented after a switch network is deployed, it is recommended to use these best practices in the planning of a network design and configuration. This document explains consideration you should make for your network before you deploy layer 2 and layer 3 switches, basic principles you should follow when planning a network, as well as important features to enable on your switches and general best practices. When installing multiple switches in a network, switched-network design practices and switch configuration can make a major difference to a Network's security, efficiency, and general health.
