Upgrading to Cisco IOS XE Release
· Upgrading from Cisco IOS XE Release 16.6 to Cisco IOS XE Release 17.x.x , on page 9 · Upgrading from Cisco IOS XE Release 3.x to Release 16.x, on page 10
Upgrading from Cisco IOS XE Release 16.6 to Cisco IOS XE Release 17.x.x
If the ROMMON version is 15.6(24r)S and the Cisco IOS XE release is 16.6.x, the router fails in the auto upgrade process during the migration to Cisco IOS XE release 17.x.x resulting in a continous boot loop. As a workaround, ensure that you upgrade the ROMMON version to 15.6(46r)S before migrating to Cisco IOS XE release 17.x.x. This issue on the router failure is specific to the following PIDs: ASR-920-12SZ-IM, ASR-920U-12SZ-IM, ASR-920-12SZ-IM-CC, ASR-920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M, and A900-RSP2A-128. Follow these steps to upgrade from 15.6(24r)S to 15.6(46r)S: 1. Copy the ROMMON pkg file asr920_15_6_46r_s_rommon.pkg to the bootflash on the Cisco ASR 920
router. 2. Use the upgrade rom-monitor filename asr920_15_6_46r_s_rommon.pkg all command to upgrade
the version. Example:
Router#upgrade rom-monitor filename bootflash: asr920_15_6_46r_s_rommon.pkg all
Upgrade rom-monitor on Route-Processor 0 Target copying rom-monitor image file ... ROMMON upgrade complete. To make the new ROMMON permanent, you must restart the RP. Router#reload <-- Reloads the active router processor and boot the IOS 17.x.x image
...
3. Reload the router, boot the router with any IOS version of 16.x.x. Example:

Release Information

Description

Cisco IOS XE Bengaluru 17.5.1

· The ROMMON image upgrade from Cisco IOS XE Release 3.x to Cisco IOS XE Everest Release 16.5.1 is not mandatory. We recommend a ROMMON upgrade for effective utilization of the new features delivered in Cisco IOS XE Everest 16.5.1 and later releases.
· We recommend you to reload the router two times for successful ROMMON and software image upgrade.
· You cannot expand the Cisco IOS XE Release 16.x image into the Cisco IOS XE Release 3.x images. The bin. file may be used to reload the image.
· Before installing the Cisco IOS XE Amsterdam Release 17.3.1, you must upgrade the ROMMON to version 15_6_43r_s or higher to avoid bootup failure. This is applicable to Cisco ASR-920-12SZ-IM, Cisco ASR-920U-12SZ-IM, and Cisco ASR-920U-12SZ-IM-CC. For Cisco ASR-920-12SZ-A and Cisco ASR-920-12SZ-D, Cisco IOS XE Amsterdam Release 17.3.1 has to be installed in sub packages mode. Booting in sub package mode takes care of auto upgrade to ROMMON version 15_6_43r_s on bootup. This workaround is not applicable to devices installed with ROMMON version 15.6(9r)S.
· For Cisco IOS XE Amsterdam Release 17.3.x, a minimum diskspace of 2 MB is required in the boot flash memory file system for a successful ROMMON auto upgrade process. For a diskspace lesser than 2 MB, ROMMON auto upgrade fails and the router reboots.
· For Cisco IOS XE Amsterdam Release 17.3.x, Cisco IOS XE Bengaluru Release 17.4.x, and earlier, the secondary ROMMON partition is not auto upgraded. You must manually upgrade it using the upgrade rom-mon filename command.
· Secure ROMMON is supported from Cisco IOS XE Amsterdam Release 17.3.1 onwards. However, it is compatible with all the releases.
· Any future secure ROMMON upgrade or downgrade is only possible from Cisco IOS XE Amsterdam Release 17.3.1 onwards.
· Starting with Cisco IOS XE Bengaluru Release 17.4.1, Cisco ASR-920-24SZ-IM, Cisco ASR-920-24SZ-M, Cisco ASR-920-24TZ-M, Cisco ASR 920-10SZ-PD, Cisco ASR-920-12CZ-A/ASR-920-12CZ-D, Cisco ASR-920-4SZ-A/ASR-920-4SZ-D, and Cisco ASR-920-20SZ-M routers are auto upgraded to ROMMON version 15_6_44r_s.
· Starting with ROMMON release version 15.6(43r)S, ROMMON version is secure. Once the ROMMON version is upgraded, it cannot be downgraded to a non-secure ROMMON version.

Upgrading the Software on the Cisco ASR 920 Series Routers 18

Upgrading the ROMMON

Auto Upgrade

· Starting with Cisco IOS XE Bengaluru Release 17.5.1, secondary ROMMON partition is also auto upgraded after a successful primary ROMMON partition upgrade is complete. You can reload the router at the next planned reload to complete the secondary ROMMON upgrade.
Note If the secondary ROMMON version is lesser than that of the primary ROMMON version, the secondary ROMMON gets auto upgraded.
· Any non-secure FPGA bundled releases moving to Cisco IOS XE Bengaluru Release 17.3.x or future releases can result in an FPGA upgrade and a ROMMON upgrade. If FPGA upgrade happens parallely with the ROMMON upgrade, you can only expect a single reload. If FPGA upgrade gets delayed and happens post ROMMON upgrade, two reloads are expected to complete both the upgrade processes. This is followed by a successful bootup of the target release image. However, starting with Cisco IOS XE Bengaluru Release 17.5.1, Cisco ASR-920-12SZ-IM, Cisco ASR-920U-12SZ-IM, Cisco ASR-920U-12SZ-IM-CC, Cisco ASR-920-12SZ-A and Cisco ASR-920-12SZ-D, ROMMON and FPGA upgrade are synchronized to happen in a single reload.
