ackgrou d / Scena io Before st rting a CCN hands-on l b that make use of either a Cisco router or switch, ensure that the devices i use have b en erased a d have no startup configurations pres nt. Otherwis , the results of your lab may be unpredictable. This lab rovides a d tail procedur e for initializi g and reloading a Cisco r outer and a Cisco s itch. Note: Note: Th routers use with CCNA hands-on la s are Cisco 941 Integrated Services outers (ISR ) with Cisco IO Release 15.2(4)M3 (universalk9 image). The switches used are Cisco Catal st 2960s wit Cisco IOS Rele se 15.0(2) (lanbasek9 image). Other r uters, switc es, and Cisco IOS versio s can be us d. Depending on the mo el and Cisco IOS version, the commands available and output pr oduced might vary from wha is shown in the labs.

Initializing and Reloading a Router and Switch
Step 2:
Power on all the devices in the topo logy .
Wait for all devices to finish the software load process before moving to Part 2.
Part 2:
Step 1:
Initialize the Router and Reload Connect to the rout er.
Console into the router and enter privileged EXEC mode using the enable command.
Rout er > enable Rout er #
Step 2:
Erase the startu p conf igur ation file from NVRAM.
Type the erase startup-config command to remove the startup configuration from nonvolatile randomaccess memory (NVRAM).

Step 3:
Reload the rout er.
Issue the reload command to remove an old configuration from memory. When prompted to Proceed with reload, press Enter to confirm the reload. Pressing any other key will abort the reload.

Part 3:
Initialize the Switch and Reload
Step 1: Connect to the switch . Console into the switch and enter privileged EXEC mode.
Determin e if there have been any virtual local-area networ ks (VLANs) created.
Use the show flash command to determine if any VLANs have been created on the switch.

Reflection 1.
Why is it necessary to erase the startup configuration before reloading the router? _______________________________________________________________________________________ The startup configuration file is l oaded into memory and becomes the running-config after the router reloads. Erasing this file allows the router to return to its basic configuration after a reload.
2.
You find a couple configurations issues after saving the running configuration to the startup configuration, so you make the necessary changes to fix those issues. If you were to reload the device now, what configuration would be restored to the device a fter the reload? _______________________________________________________________________________________ The configuration at the time of the last save is restored to the d evice after a reload. Any changes made to the running configuration after the last save would be lost.
