Cisco IOS File System Commands
This chapter describes the commands used to configure the Cisco IOS File System (IFS) in Cisco IOS
Release 12.1.
Commands in this chapter use URLs as part of the command syntax. URLs used in the Cisco IFS contain
two parts: a file system or network prefix, and a file identification suffix. The following tables list URL
keywords that can be used in thesource-url and destination-url arguments for all commands in this
chapter. The prefixes listed below can also be used in the filesystem arguments in this chapter.
In general, commands used to specify file locations use the following URL format:
prefix://username:password@location/directory-path/filename
All elements aside from the prefix and filename are optional. For example, you could specify only:prefix:filename
Table 13 lists common URL network prefixes used to indicate a device on the network.
