Network Switch Selection – How to Select a Network Switch

Overview

The network switch is the most common network device implemented with company infrastructure and as such the selection of any new switches or upgrading is a key part of most network design projects. The Cisco network switch components include Switch Chassis, Supervisor Engine, Switching Modules, IOS/CatOS software and Power Supplies. The decision to buy new switches or upgrade equipment will be decided after considering the network assessment and design features specified. Wireless designs, as an example, will have network switches interfacing with access points. That will have an affect on the switch such as increased utilization, assigned switch ports, access control lists, Trunking, Spanning Tree Protocol and increased wattage draw from Power over Ethernet (PoE).

Inter-VLAN Routing With Cisco Routers and Switches

Inter-VLAN routing is a process of forwarding network traffic from one VLAN to another using a router.
To allow devices connected to the various VLANs to communicate with each other, you need to connect an intermediary network device. For the record, each VLAN is a unique broadcast domain, so, computers on separate VLANs are, by default, not able to communicate. There is a way to permit these computers to communicate; it is called inter-VLAN routing.

One of the ways to carry out inter-VLAN routing is by connecting a router to the switch infrastructure. VLANs are connected with unique IP subnets on the network. This subnet configuration enables the routing process in a multi-VLAN network. When using a router to facilitate inter-VLAN routing, the router interfaces can be connected to separate VLANs. Devices on those VLANs communicates with each other via the router.

There are different methods for accomplishing inter-VLAN routing:

i. Traditional Inter-VLANrouting. This type of packet routing process requires multiple physical interfaces on both the router and the switch.

ii. Router-on-a-stick. This is a type of Inter-VLAN router configuration in which a single physical interface routes traffic between multiple VLANs on a network.

A router interface is configured to operate as a trunk link and is connected to a switch port configured in trunk mode. The router performs this type of routing process by accepting VLAN tagged traffic on the trunk interface coming from the adjacent switch and internal routing between the VLANs using sub interfaces. The router then forwards the routed traffic-VLAN tagged for the destination VLAN out the same physical interface.
