Upgrade Procedures for RPM-PR and RPM-XF Cards
Once you are sure that an upgrade is stable, you can use the commitrev command commit to that
software version. Committing to the current software version prevents other administrators from
inadvertently reverting to the previous version. You must also commit to the current software version
before you can upgrade to another software version.
To commit to the currently running runtime software version, use the following procedure.
Step 1 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 2 Determine if there is an unfinished upgrade by doing the following:
a. If necessary, use the cc command to select the active PXM card.
b. Enter the dspcd <slot> command.
c. Check the dspcd command report to see if the same software revision is listed for the Primary
Software Revision (Prim SW Rev), Secondary Software Revision (Sec SW Rev), and Current
Software Revision (Curr SW Rev).
If all version numbers are identical, the runtime software can be upgraded. There is no need to
commit to the current software revision.
Step 3 To commit to the software version, enter the following command:
mgx8850a.7.PXM.a > commitrev <slot> <revision>
Replace <slot> with the card slot number for the active card, and replace <revision> with the software
version number for the currently used software version. To display the software version number, use the
dspcd <slot> command to view the software version in use. You can also view the revision levels with
the dsprevs command.
Note Cisco Systems recommends that you avoid configuration changes until after you have run the
commitrev or abortrev commands.
Upgrade Procedures for RPM-PR and RPM-XF Cards
The following sections describe how to upgrade boot and runtime software on RPM-PR and RPM-XF
cards.
Note In this document, the general term “RPM” refers to RPM-PR and RPM-XF cards. If a step or procedure
is specific to only one of the RPM cards, it will be called out in the text.
Upgrading RPM Boot Software
At the factory, a boot file is installed in the bootflash on the RPM card and is used to boot the card. The
runtime software is updated more frequently than the boot software. However, the boot software is
updated occasionally. When you are updating runtime software, check the release notes that accompany
the runtime software to see if a boot software upgrade is required.
