Backing Up Labs

Before and after each lab, you will have to back up the configuration of your VMs as well as your switch and router. Make sure to do this or else the next group might overwrite your changes!

means that you’ll be typing in the terminal or what you’ll be seeing in the terminal.

Backing Up and Resetting the Switch and Router

To backup the configuration, log into the switch or router and do a “show run” to see the current configuration. Press the spacebar to go through the whole thing. Copy down the entire configuration and paste it into a text file on your computer. Save that someplace you won’t lose it.

Now we can reset the router and switch:

trainswitch# write erase
trainswitch# reload

This will factory reset and reboot the router.

Backing Up and Resetting KVM Hosts

root@richweb-host 10:31:23
 > ~ # cd /opt/rwtrainer/kvm_scripts_pristine/

root@richweb-host 10:31:31
 > /opt/rwtrainer/kvm_scripts_pristine # ./reset_env.py

All the hosts are now archived.

Restoring All Settings

To restore the switch and router, just console in, go into configure mode, and paste the saved configuration in. It is now just as you had it before.

To restore the virtual machines you had before, execute these commands:

root@richweb-host 10:31:23
 > ~ # cd /opt/rwtrainer/kvm_scripts_pristine/

root@richweb-host 10:31:31
 > /opt/rwtrainer/kvm_scripts_pristine # ./restore_env.py
