Router and Switch Configuration
When you are getting ready to add a switch to your network there are a few steps you
need to do to insure that it is running the way you want it to. The first one is easy, find a spot
where you want to place it and have easy access to it. After plugging it in you will want to use
the command line interface to get the switch configured. This can be connected to either a
management station like a PC or a Modem. To do this you connect from the console port on the

bring you to the all the menus you can use and K will take you to the CLI so you can make
changes to the network. To work with the password you type P.
VLANs can be connecting with each other when connected to the switch. In the sitting of
the switch you can limit what they can do. Don’t forget that you can also use the tree method
with VLANs. According to "Cisco" (2014), “Per-VLAN Spanning Tree (PVST) maintains a
spanning tree instance for each VLAN configured in the network. It uses ISL Trunking and
allows a VLAN trunk to be forwarding for some VLANs while blocking for other VLANs. Since
PVST treats each VLAN as a separate network, it has the ability to load balance traffic (at layer-
