Troubleshoot Cisco Switch IOS Upgrade

Hi everybody,

 

I am trying to run the script below to download a Cisco IOS image from our server that we have setup.

 

I selected "scp" and "Download Only" when starting this and the problem I am getting is that the code isn't downloading the image to the switch and when checking the commands the switch ran, it isn't there.

 

I was wondering if anybody can help me with this.

 

Thanks!

 

Script-Filter:
#	PLEASE REVIEW BEFORE USING!!!
#
#	This script content is provided to the user as is and is not 
#	warranted or guaranteed against specific vendor devices or user 
#	scenarios. It is provided by Infoblox to the user of this platform
#	as an example, and should not be executed against production network
#	devices unless the user has reviewed and/or made the proper 
#	modification to assure safe execution in specific network 
#	configurations. Please contact your Infoblox representative or 
#	Infoblox support if you have questions or concerns about how to 
#	safely use the following scripted content in your network.
#
#	You MUST check the "enable_changes" option for any commands to
#	be executed. When NOT selected, the script will log the commands it
#	would execute, but not download files or make changes to the device.
#
#	You may specify addtional path information in the server field when
#	using the ftp and http protocols.
#	
#	If multiple protocols are selected, only one will be used. Order of
#	preference is http, scp, ftp, then tftp.
#
#	The clean_flash option will attempt to free space in flash by 
#	deleting common files such as crash dumps and misc html files. 
#	If you use this option, you may want to adjust the file pattern 
#	matches in the "Delete Files" action.
#   
#	Use of scp requires that the device currently be running an image
#	with crypto support (a.k.a., a "k9" image). 
#
#	If you use scp, the password will appear in the process log of
#	the Job details viewer. Use a dedicated, restricted account for this.
#	In addition, the image file must exist in the user's home directory.
#
#	To use ftp transfer, you must first define ftp user, password, and
#	mode settings (i.e., ip ftp username, ip ftp password, ip ftp passive)
#
#	The current running image AND the new image MUST end in ".bin". 
#	This means if you are currently using a running image that was not
#	copied with its original filename intact, you must manually correct
#	this before using this script.
#
#	The script will not do a force delete of the current running image
#	from flash, if it exists. This is to help prevent leaving a device
#	without an image if there is a problem during the file copy.
#
#	The download only option will copy the new file to flash if needed,
#	but will not change the configuration or attempt to reload the device.
#
#	It is not necessary to specify either of the "reload_now" or 
#	"reload_cmd" options. Devices can be manually restarted later or
#	perhaps reloaded by another script.

	$Vendor eq "Cisco"   and
	$sysDescr like /IOS/
#	( $model like /^C29(?:6|8)\d{1}(?:SXM)?/  or
#	  $model like /^3(?:6|7|8)\d{2}(?:XM)?$/ )

Action:
	Delete Files

Action-Description:
	Delete various files if selected.  This frees up space for the new file.
	This script can only handle up to a total of nine image files in flash.

	This action requires that a download protocol was selected.  If
	one of these are not set, the new file can not be downloaded.
	
	Set the terminal length to 0 so that results are not paginated.
	You may want to adjust some of the delete statements below to suit
	your site.

########################################################################
Trigger:
	Find Running Image

Trigger-Description:
	This trigger determines the running IOS filename and calls a
	second trigger that looks for the new IOS image in flash. The
	command specifically looks only for .bin files.

Trigger-Variables:
	$currentbootimage	/\w\d{4}[\w\-\.]+\.bin/

Trigger-Template:
	flash:[[$currentbootimage]]

Trigger-Filter:
	$runscript ne "no"

Trigger-Commands:
	dir /all
	SET: $have_current_image = "yes"

Output-Triggers:
	Check Files and Delete

########################################################################
Trigger:
	Check Files and Delete

Trigger-Description:
	This trigger looks for the user-supplied new image name in the
	output of the "dir" command in the previous trigger.

	$imagename must be a string of characters ending in ".bin".

	The $file variable is used to determine each file's position in flash.
	This allows the script to keep track of the number of image files in flash.
	
	If the .bin file is not the running image or the new image delete it
	to make room.

	$dir needs to match date strings as well as <no date> in case
	a file was uploaded to the device when the date/time was not available.
	For example, it must properly pull the file sequence and .bin file
	name from both of these:

    1  -rw-     8699556  Mar 13 2007 22:27:30 +00:00  c3660-i-mz.123-9e.bin

Action-Description:
	Determine if deleted files are in flash, if so, try to squeeze the

	failed or we need to squeeze deleted files from the first action.

	This is an action so that it is not called after each file delete.

Action-Commands:
	dir /all

Output-Triggers:

########################################################################
Trigger:
	Check Space

Trigger-Description:
	This trigger determines if there is enough space in flash to load
	the new image. The dir command output from the previous trigger is
	parsed to determine free space remaining.

	If we don't already have the new image in flash, and there is not
	enough space to download it, fire an issue.

Trigger-Variables:

This is the IOS upgrade script that we provide out of the box, with the script just as is an no indications or logs as to what went wrong on your end it is hard to guess where it ran into a snag.

 

Have a look at the different job logs and share them if you want another set of eyes on them.

Hi Ingmar,

 

Here is Session Log that shows what the switch is doing when running the script.

 

From the looks of it, it doesn't even run the copy scp command to download the image from the scp server I have setup.

Based on that output and the script it fails to enter the Download IOS section. Without the full logs it is impossible to say why some things to check:

  • Did you check the use scp and enable changes flag? 
  • Is the image name you are using different from the image currently running on the box
  • Check what variables are set during runtime for the Action-Filter:
Action:
	Download IOS

Action-Description:
	Copy the new image file to flash via SCP, TFTP, FTP or HTTP.

Action-Timeout:
	5400

Action-Filter:
	$runscript ne "no" and
	$havenewimage ne "yes" and 
	$spaceavailable eq "yes" and
	$have_current_image eq "yes"

...

Action-Commands: { $usescp eq "yes" and $enable_changes eq "on" }
	copy scp://$server/$new_image_name flash:$new_image_name\r$scp_username\r\rn$scp_password\r
	verify /md5 flash:$new_image_name
	SET: $havenewimage = "yes"

Action-Commands: { $usescp eq "yes" and $enable_changes eq "off"}
	DEBUG:copy scp://$server/$new_image_name flash:$new_image_name\r$scp_username\r\rn$scp_password\r
	DEBUG:verify /md5 flash:$new_image_name
	SET: $havenewimage = "yes"

  • I have scp turned on but I did not have the enable changes flag on
  • The image on the switch is different from the one I am trying to download
    • Image on switch: c3560cx-universalk9-mz.152-4.E6.bin
    • Image trying to download: c3560cx-universalk9-mz.152-4.E8.bin
