Writing Configuration [OK]
Note: To backup the latest startup configuration file, you should save current
settings to flash first. You can refer to
how to save settings to the flash.
In the example above, 192.168.250.33 is the TFTP server's IP and
default.conf is name of the configuration file. Your environment may use
different IP addresses or different file name. Type target TFTP server IP
or file name in this command.
Switch# copy tftp: 192.168.250.33/default.conf startup-
config
Switch# show startup-config
Switch# show running-config
