A Word from our Sponsors:
There is a very fine line between writing something short-and-sweet and writing something comprehensive while losing the target “market” in the process. 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.
Introduction
Switch and/or router firmware had (past tense) a simple procedure, however,
for IOS-XE each platform has different commands, process & procedures, and
“gotchas”. Because of this, I have broken up the process into different
sections: 3850, 9300 and routers.
Section 1: General Procedure
-
Read the Release Notes very carefully.
-
Usually, IOS-XE firmware & SMU have a filename extension of “bin”.
-
Clean the flash: install remove inactive
-
Copy the file into the switch/stack master. Make sure the boot-variable string is pointing to “packages.conf” file.
-
Initiate Install Mode (DISRUPTIVE):
WARNING : The following below command will cause the switch/stack/VSS pair to reboot. Fk!
install add file bootflash:filename.bin activate commit
NOTE: Same command for VSS – The firmware will be copied to the secondary switch automatically.
WARNING: The
following above command will cause the switch/stack/VSS pair to reboot. Fk! -
[RECOMMENDED][OPTIONAL] Clean the flash: install remove inactive
-
DONE.
Install SMU
Section 2: Install SMU
Software Maintenance Update (aka “patch”)
WARNING:
- Only routers and switches running IOS-XE support SMU.
- Router(s) & switch(es) running “classic” IOS do not support SMU.
- IMPORTANT: Always treat SMU update as disruptive (reboots the switch/stack).
- IMPORTANT: SMU file is platform-specific.
- IMPORTANT: SMU file is version-specific.
Proceedure
-
Read the Release Notes very carefully.
-
Usually, SMU firmware have a filename extension of “bin”.
-
Copy the SMU file into the switch.
-
Install the SMU: install add file flash:SMU_filename.bin activate commit
WARNING: Immediately after entering “y” may/will cause the router &/or switch to reboot. -
Verify the SMU has been successfully installed.
Fast Method: sh version | begin Active SMU
-
DONE.
