Cisco 2500 IP/FW Plus IPSEC 56 Feature Pack CD25-CHL-12.0= Manual De Usuario

Release Notes for Cisco IOS Release 12.0(6) Feature Packs for the Cisco 2500 Series  13

The Cisco 2500 series upgrade utility filename is cpa2500-upgrade-l.120-6. The

upgrade utility is a special file—not a Cisco IOS run-time image, and must be located in
the Images directory. If it is not, the upgrade utility informs you that the image is not
present.

At the prompt, confirm the upgrade message. RSL then downloads the selected image.

Alternatives to RSL

RSL is designed to work with a PC running Microsoft Windows 95 and is the recommended method
for downloading software to the router; however, two alternatives are available for installing router
software:

The sample prompts and output shown in the following sections may not be identical to the

prompts displayed on the router console.

Installing the Router Software by Using the Console or Auxiliary Port

This section explains how to use the copy xmodem flash command to install the router software
from the CD-ROM onto the router.

The transfer takes place only on the port where you enter the command. If you download the

software by using the console, all console output is discarded for the duration of the transfer. You
can only download files to the router; you cannot copy files from the router. We recommend using
the auxiliary port for this type of software download, because the auxiliary port has hardware flow
control and full modem control. In addition, the transfer does not occupy the system console, so it
is free for other uses.

The following example shows how to use the copy xmodem flash command on a Cisco 2500 series
router:

Router# copy xmodem flash

                               **** WARNING ****

       x/ymodem is a slow transfer protocol limited to the current speed

       settings of the auxiliary/console ports. The use of the auxilary

       port for this download is strongly recommended.

       During the course of the download no exec input/output will be

       available.
