Chapter 5 Preparing RPM-PR Cards for Operation
Verifying the Software Version in Use
Verifying the Software Version in Use
To verify which version of software an RPM-PR card is using, you need to use Cisco IOS commands at
the router prompt for the RPM-PR card. The following example shows how to do this with the show
version command:
Router#show version
Cisco Internetwork Operating System Software
IOS (tm) RPM Software (RPM-JS-M), Experimental Version 12.1(20001205:224609)

The following line in the example above is most important:
System image file is "c:rpm-js-mz.122-4.T"
The system image file line indicates which file was used to load the software currently in use. In this
example, the software was loaded from the c: drive, which corresponds to E:/RPM on the switch. The
filename shown identifies the source file for the running image. This filename is configured in IOS
global configuration mode with the boot system command.
Establishing Redundancy Between Two RPM-PR Cards
RPM-PR cards support one-to-n (1:n) card redundancy. With 1:n redundancy, one RPM-PR card can
serve as a secondary or backup card for multiple RPM-PR cards.
Note Primary and secondary cards can run on incompatible software images. However, the software image on
the secondary card must be at the same level or higher than the software image on the primary card.
