SMU firmware have a filename extension of “bin”.

IMPORTANT: SMU file is version-specific.

IMPORTANT: SMU file is platform-specific.

IMPORTANT: Always treat SMU update as disruptive (reboots the switch/stack).

Router(s) & switch(es) running “classic” IOS do not support SMU.

Only routers and switches running IOS-XE support SMU.

Software Maintenance Update (aka “patch”)

Clean the flash: install remove inactive.

If the switch is standalone, the command is:.

If the switches are in a stack, inspect the “nf” of each switch stack member.

Is this the intended version or not? If NO, go to the GOTCHA section.

Go to the GOTCHA section if the following (image below) appears:.

If the file extraction is successful (or not), the last two lines will display the result.

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: 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.
