Software install file flash: filename.bin new force verb on-reboot NOTE: If upgrading from 3.X.X, the command is different: Request platform software package install switch all file flash: filename.bin on-reboot new auto-copy verbose

Initiate Install Mode ( Non-Disruptive/Do NOT Reboot.

Make sure the boot-variable string is pointing to “nf” file.

NOTE: Switch/stack on IOS-XE version 3.X.X, uses a different command:

Clean the flash: install remove inactive.IOS-XE firmware and SMU files have a filename extension of “bin”.Because of this, I have broken up the process into different sections: 9300, 9500 & routers. 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.9300, 9500 (vanilla & high-performance), ISR 1k, ISR 4k and ASR is not covered.This procedure is aimed at Cisco 3850 switch ONLY.
