Chapter 25 Working with System Software Images
Downloading System Software Images Using rcp
•
If you are accessing the switch through the console or a Telnet session without a valid username,
make sure that the current rcp username is the one you want to use for the rcp download. You can
enter the
show users
command to view the current valid username. If you do not want to use the
current username, create a new rcp username using the
set rcp username
command. The new
username will be stored in NVRAM. If you are accessing the switch through a Telnet session with
a valid username, this username will be used and there is no need to set the rcp username.
•
A power interruption (or other problem) during the download procedure can corrupt the Flash code.
If the Flash code is corrupted, you can connect to the switch through the console port and boot from
an uncorrupted system image on a Flash PC card.
Downloading Supervisor Engine Images Using rcp
To download a supervisor engine software image to the switch from an rcp server, perform these steps:
Step 1
Copy the software image file to the appropriate rcp directory on the workstation.
Step 2
Log into the switch through the console port or through a Telnet session. If you log in using Telnet, your
Telnet session disconnects when you reset the switch to run the new software.
Step 3
Download the software image from the rcp server by entering the
copy rcp flash
command. When
prompted, enter the IP address or host name of the rcp server and the name of the file to download. On
those platforms that support the Flash file system, you are also prompted for the Flash device to which
to copy the file and the destination filename.
The switch downloads the image file from the rcp server.
Note
The switch remains operational while the image downloads.
Step 4
Modify the BOOT environment variable by entering the
set boot system flash
device
:
filename
prepend
command, so that the new image boots when you reset the switch. Specify the Flash device (
device
:
) and
the filename of the downloaded image (
filename
).
Step 5
Reset the switch by entering the
reset
system
command. If you are connected to the switch through
Telnet, your Telnet session disconnects.
During startup, the Flash memory on the supervisor engine is reprogrammed with the new Flash code.
Step 6
When the switch reboots, enter the
show version
command to check the version of the code on the
switch.
Downloading Switching Module Images Using rcp
To download a software image to an intelligent module on a Catalyst 6000 family switch, perform these
steps:
Step 1
Copy the software image file to the appropriate rcp directory on the workstation.
Step 2
Log into the switch through the console port or a Telnet session. If you log in using Telnet, your Telnet
session might disconnect when you reset modules to run the new software.
