11/14/2022 0 Comments Cisco ios reboot![]() ![]() The Cisco IOS collection supports network_cli connections. PEP440 is the schema used to describe the versions of Ansible. Plugins and modules within a collection may be tested with only specific Ansible versions.Ī collection may contain metadata that identifies these versions. This collection has been tested against following Ansible versions: >=2.9.10. ![]() This collection has been tested against Cisco IOSv version 15.2 on VIRL. Command: emergency-install usbflash0:filename.The Ansible Cisco IOS collection includes a variety of Ansible content to help automate the management of Cisco IOS network appliances.Image above shows failed “emergency-install” because the firmware is in the flash. Emergency-Install process can only be effectively achieved by using a USB thumb drive.The “emergency-install” command can only be used in ROMMON.Emergency-Install is to be used when the switch boots into ROMMON.(Make sure the config is stored somewhere else.) WARNING: Emergency-Install command will erase the flash/bootflash of the appliance. Make sure the boot-variable string is pointing to the “nf” file.Inspect the contents of each “nf” file of every member of the stack.Check the contents of the new “nf” file.Next, rename the nf to “nf” (see below).Look in the flash/bootflash directory for two (2) files with an extension of “conf”.Check the contents of the flash/bootflash and compare the date stamp of the extracted packages against the date stamp of the “nf” file (see image below).If the message (image below) appears at the end of the package extraction process THIS IS NOT A FALSE POSITIVE.Fast Method: sh version | begin Active SMU.Verify the SMU has been successfully installed.WARNING: Immediately after entering “y” may/will cause the router &/or switch to reboot. Install add file flash:SMU_filename.bin activate commit SMU firmware have a filename extension of “bin”.Image (above): Attempting to install an SMU meant for a different version. 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.Cisco 3850: IOS-XE/Firmware Upgrade (Install Mode) ![]()
