Saving a Configuration
Use the copy running-config startup-config command to save the new configuration into nonvolatile
storage. Once this command is issued, the running and the startup copies of the configuration are
identical.
See the
page
Clearing a Configuration
Use the write erase command to clear a startup configuration. Once this command is issued, the switch's
startup configuration reverts to factory defaults. The running configuration is not affected.
Caution
The write erase command erases the entire startup configuration with the exception of any configuration
that affects the loader functionality.
The write erase boot command only erases the configuration that affects the loader functionality. The
loader functionality configuration includes the boot variables and the mgmt0 IP configuration
information (IP address, netmask, and default gateway).
switch# write erase boot
This command will erase the boot variables and the ip configuration of interface mgmt 0
Displaying Users
Use the show users command to display all users currently accessing the switch.
switch# show users
admin

Sending Messages to Users
Use the send command to send a message to all active CLI users currently using the switch. This
message is restricted to 80 alphanumeric characters with spaces.
This example sends a warning message to all active users about the switch being shut down.
switch# send Shutting down the system in 2 minutes. Please log off.
Broadcast Message from admin@excal-112
Shutting down the system in 2 minutes. Please log off.
