Commonly used viewing commands
View flash files, system
Router#show flash
View version
Router#show version
View CPU utilization
Router#show process
You can view the code at a fixed point
High-end commands can only be executed on EV
Router#show running-config | section dchp
View brief information about the interface
Router#show ip interface brief
Interface: interface number: enternet0/0
IP-Address: ip address
Method: Obtaining method: manual (manual) and DHCP (automatic)

simple file transfer protocol
Turn on the TFTP function on the server
FTP
file transfer protocol
Direct copy and paste will cause errors, so you need to transfer the file
Configuration file backup
branch
Copy the current configuration information to the TFTP server
Router#copy running-config tftp:
The address of the device where TFTP is located
Address or name of remote host [ ]? 192.168.10.2
The file name after copying to the target
Destination filename [Router-confg]?
branch
Copy files on TFTP to RAM
Router#copy tftp: running-config
The address of the device where TFTP is located
Address or name of remote host []? 192.168.10.2
To copy the file on TFTP (note the case)
Source filename []? Router-confg
The file name after reaching the target
Destination filename [running-config]?
System backup and upgrade
That is, the copy system
First check the system files
Router#show flash
Copy system files to TFTP server
Router#copy flash: tftp:

Router#copy tftp: flash
Address or name of remote host []? 192.168.10.2
Source filename []? c1841-advipservicesk9-mz.124-15.T1.bin
Destination filename [c1841-advipservicesk9-mz.124-15.T1.bin]?
%Warning:There is a file already existing with this name
Do you want to over write? [confirm]
Disaster recovery
It was found that system files were not transferred to tftp, which did not affect recovery.
Simulate equipment system failure scenarios
Router#delete flash
Delete system files
Delete filename []?c1841-advipservicesk9-mz.124-15.T1.bin
Delete flash:/c1841-advipservicesk9-mz.124-15.T1.bin? [confirm]
The device is a process system. The process has not ended yet. We can still configure it, so we terminate it manually.
