Troubleshooting Software Mismatch with ESP Board ASR1000-ESP10-N
The Cisco ASR 1000 ESP board ASR1000-ESP10-N enables you to install a Cisco ASR 1000 Series
Aggregation Services Router without encryption features. This unrestricted product format, in which all
encryption chips have been removed, can be provided in the Cisco ASR 1002, 1004, and 1006 Series
Routers. This ESP must be used with the appropriate Cisco IOS XE 2.2 image that does not contain
encryption software.
You cannot load Cisco IOS XE software images or subpackages which contain encryption software, onto
a Cisco ASR 1000 Series Router that contains the non crypto enabled ESP board (ASR1000-ESP10-N).
As soon as the combination of an encryption-enabled Cisco IOS XE image and encryption-disabled ESP
is detected—on bootup, online removal or insertion, or during an install—a message is emitted:
ESP[0|1] does not support strong cryptography. Chassis will reload.
The Route Processor (RP) then reloads the chassis and reboots continuously.
To troubleshoot this problem, follow these steps:
Step 1 Enable ROM Monitor (ROMmon) mode by entering the reload command.
Step 2 Press the Break key during the first 60 seconds while the system is booting.
Step 3 Force the system to remain in ROMmon mode, waiting for manual bootup, by entering the command:
confreg 0x0.
Step 4 Load the latest Cisco IOS XE package or subpackages that are compatible with the ASR1000-ESP10-N
ESP board.
Compatible subpackages include:
–
Cisco ASR1000 Series RP1 IP BASE W/O CRYPTO
–
Cisco ASR1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO
–
Cisco ASR1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO
Step 5 Remove the forced manual boot mode by entering the command: confreg config register setting, where
config register setting is the default for the user system, often 0x2102.
Step 6 Reboot the system.
Upgrading Individual SubPackages
One consolidated package contains seven individual subpackages. Each individual subpackage can be
upgraded independently.
When using this method to upgrade subpackages, however, remember that all subpackages that are part
of the same consolidated package should be used together on the Cisco ASR 1000 Series Routers.
Individual subpackage upgrades are atypical on the Cisco ASR 1000 Series Routers, because it is very
rare to experience a case where a single subpackage is upgraded without upgrading all the subpackages
from the consolidated package. Individual subpackage upgrades are most useful when only a single
subpackage of an otherwise functioning set of subpackages requires an upgrade.
This section uses the SPA subpackage installation to illustrate an individual subpackage upgrade.
Although it does not comprehensively cover every possible individual subpackage upgrade scenario, the
CLI for each type of upgrade is similar.
