10 CISCO command that you should know

Just like a Windows or Linux operating system, the Cisco IOS has its own list of commands to manipulate files, very similar to DOS/Windows commands. These files could be your IOS router operating system, configuration file, or other type of IOS file. Knowing these file commands is a critical requirement for any Cisco admin.

Let’s look at 10 Cisco IOS file management commands you must know.

#1 dir

This shows a directory list of files on a filesystem. To see the options, type dir ?

Router#dir ?

/all             List all files

/recursive       List files recursively

all-filesystems  List files on all filesystems

archive:         Directory or file name

cns:             Directory or file name

flash:           Directory or file name

null:            Directory or file name

nvram:           Directory or file name

system:          Directory or file name

tar:             Directory or file name

tmpsys:          Directory or file name

xmodem:          Directory or file name

ymodem:          Directory or file name

<cr>

Router#

You can think of each of these filesystems almost like disk drives in DOS, where you have to put a colon after the name. So, the nvram is called nvram:. The default is to show a directory of the router’s flash as your default current directory is flash:

Router# dir

Directory of flash:/

2  -rwx    18929780  Aug 29 2006 15:49:57 +00:00  c870-advipservicesk9-mz.124-15.T5.bin

3  -rwx        2143  Aug 29 2006 16:42:14 +00:00  running-config

23482368 bytes total (4544512 bytes free)

Router#

Every router will have at least flash memory and nvram (non-volatile random access memory).

#2 cd

Change directory: Use cd to change your current directory to a different device or subdirectory on that device. In the following, when I change my directory to the nvram: filesystem and do a dir, I get a list of nvram. I could also cd to a subdirectory after I have created a directory with mkdir.

Router#cd nvram:

Router#dir

Directory of nvram:/

126  -rw-        2143                    <no date>  startup-config

127  ----           5                    <no date>  private-config

128  -rw-        2143                    <no date>  underlying-config

1  ----          49                    <no date>  persistent-data

2  -rw-           0                    <no date>  ifIndex-table

131072 bytes total (116584 bytes free)

Router#

#3 copy

This is used to copy the IOS or a config file from and to somewhere. You would use this to copy the router’s configuration off the router to a TFTP server or just make a local backup of it on the router. You would also use the copy command to upgrade the router with a new IOS from a TFTP server.
