Chapter 3 Configuring the Catalyst 4840G Processor
Using Flash PC Cards
The following is an example of the delete and squeeze commands used together. Note that the delete
command requires you to specify the filename, while the squeeze command requires that you specify
the Flash memory media (for example, slot0:).
SLB-Switch# delete cat4840G-in-mz.X.bin
SLB-Switch# dir
Directory of slot0:/
4 -rw-2386May 11 1999 17:25:36 startup-config
16384000 bytes total (9360836 bytes free)
SLB-Switch#
The image file is marked for deletion. Enter the squeeze command to complete the operation:
SLB-Switch# squeeze slot0:
All deleted files will be removed, proceed? [confirm] y
Squeeze operation may take a while, proceed? [confirm] Y

SLB-Switch# dir

12869836 bytes available (1825540 bytes used)
Table 3-1 describes the output that is generated from a squeeze command.
