Initiate the ROMMON upgrade: upgrade rom filename bootflash:filename.pkg all.Copy the ROMMON file into the bootflash.Check current ROMMON firmware: sh platform.IMPORTANT: When in doubt, upgrade the ROMMON. Is this the intended version or not? If NO, go to the GOTCHA section. Go to the GOTCHA section if the following WARNING message (image below) appears:.If the file extraction is successful (or not), the last two lines will display the result.Request platform software package expand file bootflash: filename.bin force verbose ![]() Initiate Install Mode ( Non-Disruptive/Does NOT Reboot ).Make sure the boot-variable string is pointing to “nf” file.If “bootflash:” is not used, the router will boot into ROMMON - CSCvg37458. WARNING: Cisco IOS-XE routers strictly enforce the file location of “bootflash:”. Clean the bootflash: request platform software package clean.IOS-XE firmware have a filename extension of “bin”.Section 3: Cellular Modem Firmware Upgrade.Because of this, I have broken up the process into different sections: Switch and/or router firmware had (past tense) a simple procedure, however, for IOS-XE each platform has different commands, process & procedures, and “gotchas”. I have done all I can to make this document as “digestible” as possible without losing much of the important content but still maintaining some forward momentum. There is a very fine line between writing something short-and-sweet and writing something comprehensive while losing the target “market” in the process. Router(s) & switch(es) running “classic” IOS is not covered.3850, 93 (vanilla & high-performance) is not covered.This procedure is aimed at Cisco ISR 1k, ISR 4k and ASR 1k router ONLY. ![]()
