Upgrade the ROM monitor image in RP1 using the upgrade rom-monitor slot sec-rp-slot command. If
Step 8
the routine finds that an upgrade is necessary, the new code will begin to be loaded. Once complete,
reload the standby RP using the hw-module standby reload command.
Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S
If your RPs are running a software image prior to Cisco IOS Release 12.0(24)S, you must use the
following procedure to upgrade the RP ROM monitor, which requires a reboot of the router.
In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.
After you enter the configuration to load the new Cisco IOS software image, reload the standby PRP
Step 1
(RP2) using the hw-module standby reload command.
Step 2 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the redundancy
force-switchover command. Once RP2 becomes active, the line cards will be reloaded.
Step 3 As soon as the "Press RETURN to get started!" message appears on the console, enter enable mode and
use the upgrade rom-monitor slot rp-slot command. If the routine finds that an upgrade is necessary,
the new code will begin to be loaded. The router will reload once the ROM monitor upgrade has
completed.
RP1 will now be active. As soon as the "Press RETURN to get started!" message appears on the console,
Step 4
enter enable mode and use the upgrade rom-monitor slot rp-slot command. If the routine finds that an
upgrade is necessary, the new code will begin to be loaded. The router will reload once the ROM monitor
upgrade has completed.
Step 5 RP2 will be primary now. Let the router return to full operation with IGP and EGP peers established (this
may take a considerable amount of time, depending on the size and complexity of the router
configuration).
Check the line card CPU utilization using the execute-on all show proc cpu | inc CPU command. If the
Step 6
CPU utilization has stabilized at the normal running level, proceed with the next step; otherwise, wait
another five minutes and check again.
Upgrade the Mbus-agent-rom using the upgrade mbus-agent-rom all command. Normal forwarding
Step 7
operation of the line cards will not be affected during the upgrade. The line cards do not need to be
reloaded. If any error messages are displayed (see following example), repeat this step before contacting
Cisco TAC.
MBus agent ROM upgrade failed on slot 7 (rc=5)
MBus agent ROM upgrade failed on slot 8 (rc=6)
Use the show version command. If there is an error message at the bottom of the output indicating that
Step 8
a Fabric-downloader code upgrade is required, use the upgrade fabric-downloader all command.
Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do
not need to be reloaded. If any error messages are displayed (see following example), repeat this step
before contacting Cisco TAC.
Fabric-downloader upgrade failed on slot 7 (rc=5)
Fabric-downloader upgrade failed on slot 8 (rc=6)
