Sama seperti biasa, berikut terlampir turotial untuk mereset catalyst, saya udah nyoba di catalyst 2960, dan berhasil , enjoy it….
Reset Switch Configuration
To reset the switch to factory default, issue the erase startup-config or write erase command. This command does not clear the boot variables, such as config-register and boot system settings. You can alter the boot system parameters with the boot command. In Catalyst 4500/4000 and 6500/6000 series switches running Cisco IOS Software, you can change the configuration register value with the config-register command.
This example shows how to reset a switch running Cisco IOS Software to factory defaults with the write erase command:

At this stage, the switch configuration has reset to the factory defaults, with the exclusion of the VLAN information.
Reset VLAN Information
To reset the VLAN information to the factory defaults, delete the vlan.dat file from the Flash or NVRAM and reload the switch. On the 6500/6000 series switches running Cisco IOS Software, the vlan.dat file is stored in const_nvram. On the 4500/4000 series switches running Cisco IOS Software, the vlan.dat file is stored in cat4000_flash:. On the 2940, 2950/2955, 2970, 3550, 3550, 3560, 3570, and 2900XL/3500XL fixed configuration switches, the vlan.dat file is stored in flash:.
To erase the vlan.dat file on the 6500/6000 switches, issue the erase const_nvram: command. On the 4500/4000 switches, issue the erase cat4000_flash: command. On the fixed configuration switches, issue the delete flash:vlan.dat command.
The example steps show how to delete the VLAN information on Catalyst fixed configuration switches. You can use the same steps, with their respective commands, for the 6500/6000 and 4500/4000 running Cisco IOS Software:
- To verify the VLAN information, issue the show vlan command, and to verify the vlan.dat file, issue the dir command.

- Delete the VLAN information from Flash or NVRAM, and reload the switch.Note: On the 6500/6000 and 4500/4000 running early versions of Cisco IOS Software, the delete command may not work. Instead, you must issue the command erase const_nvram: or the command erase cat4000_flash:. Do not specify the vlan.dat file in the command syntax. However, on later versions of Cisco IOS Software, the delete const_nvram:vlan.dat command works for the 6500/6000, and the delete cat4000_flash:vlan.dat command works on the 4500/4000.

- After reload, check the VLAN information with the show vlan command.The user-configured VLANs no longer appear in the command output. Only factory-default VLAN information is on the switch.
