Overview
The DOS file system on the router reads and writes to the diskette. The diskette
gives the system access to the software image and configuration file during a cold
start. (A cold start occurs after you cycle power on the router.)
The DOS file system accepts the DOS commands that you use to manage the files
and directories on the diskette. (For a list of these commands, see Table 5-1.
)
To alert the system that the diskette is available for access, issue the
mount a:
command. DOS performs an implied mount if you issue any of the DOS file
management commands listed in Table 5-1
(except, of course, the
unmount
command).
The Wildcard column of Table 5-1
indicates whether you can use wildcards (
*
and
?
) when entering the commands. You use wildcards to display multiple file
names, and to copy or delete multiple files. The wildcards mean the same in DOS
as in UNIX:
•The
*
wildcard matches any number of characters, including zero characters.
•The
?
wildcard matches any single character. A match occurs only when a
character is present in the position indicated by the wildcard.
Caution:
Be sure to issue the
unmount
command as described in this chapter
before you remove a diskette, reboot the router, or reset slot 2. File corruption
errors can occur when you perform these tasks without first issuing the
unmount
command.
Note:
The DOS file system in the router does not format diskettes; however,
you can format them on a PC and use them in the router.
