Step 5
dspcd
commitrev <slot> <revision>
Verify that all previous upgrades are committed.
If a previous upgrade is not committed, commit to the new
upgrade.
See the “
Committing to a Runtime Software Upgrade
” section,
which appears later in this appendix.
Step 6
loadrev <slot> <revision>
dspcd
Define the new software version to be used.
Step 7
runrev <slot> <revision>
dspcd
Reset the card and run the new software version.
Step 8
commitrev <slot> <revision>
This command prevents an accidental switch back to a previous
software revision if someone enters the abortrev command.
Enter the commitrev command after the upgraded card reaches
the active state. Cisco Systems recommends that you avoid
configuration changes until after you have run the commitrev or
abortrev commands.
See the “
Aborting a Runtime Software Upgrade
” section and the
“
Committing to a Runtime Software Upgrade
” section, both of
which appear later in this appendix.
