- Step 1
| Alert: In production, networks issue these commands with extreme caution. Never issue such commands if you have not adequately backed up your configurations.
NYACCESS1# erase startup-config Press Enter. Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] Press Enter. You will see the following output: NYACCESS1#erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [OK] Erase of nvram: complete NYACCESS1# *Mar 1 00:12:50.694: %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram Once you have erased the startup configuration, use the show startup-config command once more, you will notice that there is no startup configuration once again. Leave the switch in its current state and move on to the next section. Task 4 - Viewing System InformationThe final command in this task enables you to view which operating system version the switch is running and a number of other technical details such as modules or interfaces that are installed in the device, memory information, processor type, and seed as well as license features. You can have multiple operating system files stored in the device’s flash memory. In a later module, you will learn how to manage these files. However, for now, you will just view which operating system the device is currently running. Step 1Connect to NYACCESS1 switch. Issue the following command and examine the output: NYACCESS1# show version Press Enter. You will see the following output: NYACCESS1#show version Cisco IOS Software, C2960 Software (C2960-LANLITEK9-M), Version 15.0(2)SE9, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2015 by Cisco Systems, Inc.
