Cisco Cisco IPS 4255 Sensor

We recommend copying the current configuration file to a remote server before upgrading.

Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a 
remote server. You can then restore the current configuration from the remote server. You are prompted 
to back up the current configuration first.

The following options apply:

/erase—Erases the destination file before copying. 

This keyword only applies to the current-config; the backup-config is always overwritten. If this 
keyword is specified for destination current-config, the source configuration is applied to the system 
default configuration. If it is not specified for the destination current-config, the source 
configuration is merged with the current-config.

source_url—The location of the source file to be copied. It can be a URL or keyword.

destination_url—The location of the destination file to be copied. It can be a URL or a keyword.

current-config—The current running configuration. The configuration becomes persistent as the 
commands are entered.

backup-config—The storage location for the configuration backup. 

The exact format of the source and destination URLs varies according to the file. Here are the valid 
types:

ftp:—Source URL for an FTP network server. The syntax for this prefix is:

ftp://[[username@]location][/relativeDirectory]/filename

ftp://[[username@]location][//absoluteDirectory]/filename

You are prompted for a password. 

scp:—Source URL for the SCP network server. The syntax for this prefix is:

scp://[[username@]location][/relativeDirectory]/filename

scp://[[username@]location][//absoluteDirectory]/filename

You are prompted for a password. You must add the remote host to the SSH known hosts list.

http:—Source URL for the web server. The syntax for this prefix is:

http://[[username@]location][/directory]/filename

The directory specification should be an absolute path to the desired file.

https:—Source URL for the web server. The syntax for this prefix is:

https://[[username@]location][/directory]/filename
