Introduction to the Cisco IOS
Current configuration:
!
version 12.0
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname Router
ip subnet-zero
frame-relay switching
!
[output cut]
The sh start command--the shortcut for the show startup-config
command--shows us the configuration that will be used the next time the
router is reloaded. It also tells us how much NVRAM is being used to store
the startup-config file:
Router#sh start
Using 4850 out of 32762 bytes
!
version 12.0
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname Router
!
!
ip subnet-zero
frame-relay switching
!
[output cut]
You can delete the startup-config file by using the erase startup-
config
command, after which you'll receive an error if you ever try to view
the startup-config file.
Router#erase startup-config
Erasing the nvram filesystem will remove all files!
