System Configuration Guide
Resetting the switch to default configuration
The restore factory-default command resets the switch or stack to its
default configuration.
The syntax for the
restore factory-default command is:
restore factory-default [ -y ]
where the [ -y ] parameter instructs the switch not to prompt for confirmation.
If the
[ -y ] parameter is not included in the command, the following message
appears:
Warning the switch/stack will be reset to factory default
configuration
Do you wish to continue (y/n) ?
Enter y to restore the switch to default.
The
restore factory-default command is in the privExec command mode.
Using DNS to ping and telnet
Using the Domain Name Server (DNS) client, you can ping or telnet to a host
server or to a host by name. To use this feature, you must configure at least one
DNS; you may also configure a default domain name. If you configure a default
domain name, that name is appended to hostnames that do not contain a dot. The
default domain name and addresses are saved in NVRAM.
The hostnames for ping and telnet cannot be longer than 63 alphanumeric
characters, and the default DNS domain name cannot be longer than 255
characters. This section covers these commands:
• “show ip dns command” on page 262
• “ping command” on page 262
• “ip name-server command” on page 263
• “no ip name-server command” on page 264
