The examples below use the 12.2(8r)T2 ROMMON image. Two procedures are provided for copying ROMMON images to the Cisco 2691, Cisco 3631, Cisco 3725, and Cisco 3745 routers: copy tftp to the internal or external flash memory using the upgrade command, and another, using the upgrade command with the tftp path in the file url argument. These ROMMON images are backward compatible with all Cisco IOS images released for the Cisco 2691, Cisco 3631, Cisco 3725, or Cisco 3745 routers. To prevent this from occurring, and to ensure a smooth transition to Cisco IOS Release 12.2(13)T and later IOS releases on the Cisco 2691,Ĭisco 3631, Cisco 3725, and Cisco 3745 routers, you must ensure that a 12.2(8r)T2 or later ROMMON image is downloaded from the website onto a TFTP server, and then loaded onto the router before running the new Cisco IOS images. Attempting to run Cisco IOS Release 12.2(13)T or laterĬisco IOS releases without first ensuring that a newer ROMMON image is installed causes the router to operate improperly and enter into an unrecoverable state. The Cisco IOS images available on Cisco IOS Release 12.2(13)T and later releases require the use of the ROMMON image version 12.2(8r)T2. ROMMON image upgrades are supported on the following routers: Obtaining Technical Assistance Supported Platforms.This document contains the following sections: If you have received a Cisco 2691, Cisco 3631, Cisco 3725, orĬisco 3745 router with a Cisco IOS Release 12.2(13)T or later image already installed, you do not need to upgrade the ROMMON image. This ROMMON image upgrade is required only if you are upgrading Cisco IOS images to Cisco IOS Release 12.2(13)T or later releases. When you attempt to upgrade Cisco IOS images to Cisco IOS Release 12.2(13)T or later releases on Cisco 2691, Cisco 3631, Cisco 3725, and Cisco 3745 routers, you must first ensure that ROMMON image version 12.2(8r)T2 or a later image is installed on the router.Ĭaution Failure to upgrade the ROMMON image to version 12.2(8r)T2 or a later image before upgrading the Cisco IOS image causes the router to operate improperly and enter into an unrecoverable state.
