Resetting Switch Configuration Including VLAN Configuration Files
Resetting Switch Configuration Including VLAN Configuration Files
To reset a switch to factory default settings use the erase statup-config or write erase command. These commands will not clear config-register or boot system settings. Boot system parameters are modified by using the boot command.
Note: If you don't have access to priveleged EXEC mode you must use the Recover Cisco Catalyst 2960 Switch Password process first.
1. Enter the write erase command from priveleged EXEC mode.
Cat2950# write erase Erasing the nvram filesystem will remove all files! Continue? [confirm]y[OK] Erase of nvram: complete
2. Reload the switch by entering the reload command.
Cat2950# reload System configuration has been modified. Save? [yes/no]: n !--- Do not save the configuration at this prompt. Otherwise, the switch !--- reloads with the current running configuration and does not reset to default. Proceed with reload? [confirm]y
When the reload is complete the switch has been reset to factory defaults except for the VLAN configuration.
Reset VLAN Configuration
1. Use the show VLAN command to verify the VLAN Information.
Cat2950# show vlan
