2960 - Factory Defaults
Procedure to reset a Cisco 2960 (or 2950) to factory defaults by deleting the configuration files.
Connect the blue console cable, and open a TTY session: 9600,8,n,1.
- Hitting return should give a prompt, confirming the connection.
Press and hold the front panel MODE button, and power-up the switch.
- After a few seconds, the following should display. Release the MODE button.
The system has been interrupted prior to initializing the flash filesystem. The following commands will initialize the flash filesystem, and finish loading the operating system software: flash_init load_helper boot
At the prompt, enter the following command:
switch: flash_init Initializing Flash...
List the files in the flash directory:
switch: dir flash: Directory of flash:/ 2 -rwx 5 <date> private-config.text 4 -rwx 5048591 <date> c2960-lanbasek9-mz.122-25.SED.bin 5 drwx 192 <date> c2960-lanbase-mz.122-25.SEE2 620 -rwx 2061 <date> config.text 19752960 bytes available (12761088 bytes used)
Delete the flash file(s) config.text, and vlan.dat (if exists), and re-boot:
switch: del flash:config.text Are you sure you want to delete "flash:config.text" (y/n)?y File "flash:config.text" deleted switch: boot Loading "flash:c2960-lanbasek9-mz.122-25.SED.bin"...@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
When the switch reboots, it will launch the 'System Configuration Dialog', which you can optionally exit!
To enable the default VLAN 1 (all ports are in this VLAN by default):
Switch>en Switch#config t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#int vlan 1 Switch(config-if)#no shut 00:15:09: %LINK-3-UPDOWN: Interface Vlan1, changed state to up 00:15:10: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up Switch(config-if)#end Switch#wr mem
To change the switch hostname to something descriptive:
Switch>en Switch#config t Switch(config)#hostname PBXBOOK PBXBOOK(config)#end PBXBOOK#wr mem
