# IOSvL2
Previously, we installed an image, now we will test it.
1. I drag a second instance of the switch into the workspace.
2. I select connections from the toolbar and link the two switches using gi0/0 on each.
3. Click the label button to see the connection labels and then click the start button to power up the devices.
4. Click the Console button to access the devices. It is a bit slow to boot up and CPU and Memory go to 100% on the VM while it is doing so.
5. Time to do a quick test. I configure the two switches as shown. Do not worry for now if you don’t understand the significance of the commands.
```
# Switch 1
en
conf t
host Switch1
int vlan 1
ip address 192.168.1.1 255.255.255.0
no shut
exit
exit
wr mem
```
```
# Switch 2
en
conf t
host Switch2
int vlan 1
ip address 192.168.1.2 255.255.255.0
no shut
exit
exit
wr mem
```
6. I can now do a ping test between switches.
The first ping always fails, we will cover why in lectures! And we will not be using VLAN1, but this was fine for a test.
## Finally
You must save the configuration of each device as you would in the real world. At the console of each device, type **write memory**, most of us shorten that to **wr mem**
Save your work and exit, you can then shut down GNS3.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://johnoraw.gitbook.io/lnp/2.gns3/appliances/iosvl2.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
