You can provide the
directory argument in the following two ways in this chapter.
l
In the form of [drive] [path]. In this case, the
argument can be a string containing 1 to 64 characters.
l
By specifying the name of a storage device, such
as flash:/ and cf:/.
You can provide the
file-url argument in the following two ways in this chapter.
l
In the form of [drive] [path] [file name]. In
this case, the argument can be a string containing 1 to 64 characters.
l
By specifying the name of a storage device, such
as flash:/ and cf:/.
To facilitate management on storage devices
such as the Flash of a switch, An Ethernet switch has the file system module
built in. The file system allows you to access and manage files and
directories, such as the operations of creating/deleting/modifying/renaming a
file or a directory and displaying the contents of a file.
By default, a switch prompts for confirmation
before executing the commands which have potential risks (for example, deleting
and overwriting files).
l
S7506R switch support SRPU switchover. Both the
primary and the secondary SRPU have file system built in for you to manipulate
the files on the both SRPUs. Note that the URL of a file on the secondary SRPU
must begin with slot[No.]#flash:/, where No. is the number of the slot where
the secondary SRPU is seated. Assume that the secondary SRPU is seated in slot
1, then you need to use slot1#flash:/text.txt to identify the file named
text.txt and residing in the root directory of the secondary SRPU.
You can use CF (compact flash) card on a
S7500 series switch to extend the memory space. A CF card can be seated in the
compact flash slot of a SRPU.
l
With a CF card seated in the compact flash slot,
you can access the root directory of the CF card by executing the cd cf:
command.
l
The commands used to manipulate files, such as dir,
copy, delete, and move, apply to the files on a CF card.
l
You can disable a CF card by using the umount
cf: command. To use a disabled CF card again, you need to remove it and
install it again.

1.1.4 Directory-Related Operations
The file system provides directory-related
operations, such as:
l
Creating/deleting a directory
l
Displaying the information about the files or
the directories in the current directory or a specified directory
Table 1-3
lists the directory-related operations.
Table 1-3 Directory-related operations
|

Command
|
Description
|
|
Create a directory
|
mkdir directory

] [ file-url ]
|
Optional
|
|
Enter a specified directory or switch to
a specified storage device
|
cd directory
|
Optional
|
In the output
information of the dir /all command, deleted files (that is,
those in the recycle bin) are embraced in brackets.
The file system also provides file-related
operations, such as:
l
Deleting a file
l
Restoring a deleted file
l
Deleting a file completely
l
Managing a configuration file
l
Renaming a file
l
Copying a file
l
Moving a file

Table 1-4
lists the file-related operations.
Table 1-4 File-related
operations
|
Operation
|
Command
|
Description
|
|
Delete a file
|
delete [ /unreserved
] file-url
|
Optional
A deleted file can be restored if you
delete it by executing the delete command with the /unreserved
keyword not specified. You can use the undelete command to restore a
deleted file of this kind.
|
|
Restore a deleted file
|
undelete file-url
|
Optional
This operation can only restore the files
deleted with the /unreserved keyword not specified.
|
|
Delete a file in the recycle bin
|
reset recycle-bin [ file-url ] [ /force ]
|
Optional
|
|
Rename a file
|
rename
fileurl-source fileurl-dest
|
Optional
|
|
Copy a file

Execute a batch file
|
execute file-url
|
Optional
|
Caution:
l
For deleted files whose names are the same, only
the latest deleted file can be restored.
l
The files which are deleted using the delete
command with the /unreserved keyword not specified are actually moved to
the recycle bin and thus still take storage space. You can clear the recycle
bin to make room for other files by using the reset recycle-bin command.
l
In the output information of the dir /all
command, deleted files (that is, those in the recycle bin) are embraced in
brackets.
l
If the configuration files are deleted, the
switch adopts the default configuration parameters when it starts the next
time.
l
The execute command cannot be executed
recursively.
1.1.6
Storage Device-Related
Operations
With the file system, you can format a
storage device, such as the Flash or a CF card. Note that the format operation
leads to the loss of all files on the storage device and is irretrievable. For
memory spaces that are unavailable due to unexpected errors, you can use the fixdisk
command to restore them.

You can set the file system prompt mode to
be alert or quiet. When in the alert mode, the file system
prompts for confirmation when you perform irreversible operations (such as
deleting a file completely or overwriting a file). If you are in the quiet
mode, you are not prompted when you execute the operations.
Table 1-6
lists the operations to configure the file system prompt mode.
