Join Denise Allen-Hoyt for an in-depth discussion in this video Exploring the switch and the network topology, part of Up and Running with Cisco CLI Switch Configuration.
- The switch I have selected for this demonstration is a Cisco 2950 catalyst swich, running iOS 2950 software. It includes flash memory. The iOS image is stored there as well as the VLAN database. That VLAN database file is called vlan.dat. Additionally, there's NVRAM, and the NVRAM is a special type of flash memory that is used to store the configuration file.
The commands on the switch depend not only on the type of switch that you are using, but also on active iOS version that is running on the switch. Additionally, the commands in Packet Tracer may differ from those commands that are available on an actual switch. I'm now gonna show you the Packet Tracer topology I'm going to use for this course. The Packet Tracer topology includes three routers, west, north, and east. It includes three switches, the west switch, the east switch, and the north switch.
There are six host PCs which are attached to each of the switches with Ethernet cables. Additionally, there is a connection out to the ISP. Finally, the routers west to north, and north to east are connected with red serial cables. And that's the Packet Tracer topology.
