If you want to clear the configuration of a specific module on the switch, issue the clear config command, as shown below. The configuration takes effect immediately and the switch returns to the factory default configuration. Console> (enable) Console> (enable) When the configuration is erased, you do not need to reload the switch. Use 'session' command to clear ATM or Router specific configurations. Do you want to continue (y/n) ? y Aug 03 15:16:19 %MLS 5 MCAST_STATUS:IP Multicast Multilayer Switching is disabled System configuration cleared. This command will cause ifindex to be reassigned on the next system startup.
RESET CISCO 2950 SWITCH TO DEFAULT HOW TO
The following example shows how to reset the configuration on the switch to factory defaults: Cat5k> (enable) clear config all This command will clear all configuration in NVRAM.
To clear the configuration on 元 modules, access the 元 module by issuing the session command and resetting the switch to factory defaults using procedure in the Resetting Catalyst Switches Running Cisco IOS section of this document. If your switch has any Layer 3 (元) modules, such as Route Switch Modules (RSMs)/Route Switch Feature Cards (RSFCs) on Catalyst 5000s or the Mutilayer Switch Feature Cards (MSFCs) on Catalyst 6000s, the clear config all command will not clear the Cisco IOS configuration on this 元 module. TheĤ boot variable settings can be altered by issuing the set boot command. This command will not, however, clear the boot variables, such as config register and boot system settings. The command syntax is as follows: clear config The clear config all command clears the user configured system, as well as module configuration. The system or module configuration on these switches can be reset to factory defaults by issuing the clear config command. On Cisco IOS, the configuration must be saved by issuing the write memory command. The configuration is saved in the NVRAM automatically wherever users enter the commands in enable mode. These switches store the configuration in NVRAM. To upload a configuration file on a TFTP server, refer to the following document: Working with Configuration Files Resetting Catalyst Switches Running CatOS This procedure applies to Catalyst 4000/5000/6000 switches running CatOS. Once you clear the user configuration, there is no way to recover that configuration without restoring the backed up configuration.
RESET CISCO 2950 SWITCH TO DEFAULT PASSWORD
Refer to the following document for steps to recover the passwords on your Catalyst switches: Password Recovery Procedures Before You Begin Before resetting the switch to factory defaults, make sure to backup your configuration on a Trivial File Transfer Protocol (TFTP) server, or locally on the bootflash or slot0: device. You will need to follow the password recovery procedures for your switch. If you forget the console and enable password of your switch, you can not reset the switch configuration to factory default to reset the password. You will also need the console/enable passwords. To reset the Catalyst switches to factory defaults, you need access to the switch console using either a physical console or a Telnet connection.
This document provides information and sample command logs for resetting your switches.
If you have configured a switch and the configuration has become very complex or if you want to move a switch from one network to other, you can reset the switch to factory defaults and configure it as a new switch. This is useful when you want to remove an undesirable configuration that is present in the switch. 2 Table of Contents Resetting Catalyst Switches to Factory Defaults.1 Introduction.1 Before You Begin.1 Resetting Catalyst Switches Running CatOS.1 Resetting Catalyst Switches Running Cisco IOS.2 Resetting Switch Configuration.3 Resetting VLAN Information.4 Resetting Catalyst Switches in Redundant Mode.5 Related Information.6 iģ Resetting Catalyst Switches to Factory Defaults Introduction Before You Begin Resetting Catalyst Switches Running CatOS Resetting Catalyst Switches Running Cisco IOS Resetting Switch Configuration Resetting VLAN Information Resetting Catalyst Switches in Redundant Mode Related Information Introduction In certain situations, it is desirable to restore the Catalyst switch configuration to the original default factory settings.
