Config snippets : Cisco: Reload command might be handy


Few times in the past when I was doing some changes on Cisco devices remotely I was a victim of myself, when wrong order of commands just disconnected me from device without ability to connect back. After few experiences of this kind I discovered magic command “reload” which can help and save the day.

So, when doing changes which can impact remote terminal connection to device it’s a good idea to initiate reload before making changes. In case something goes wrong device will reboot itself and will come back with previous configuration.

lab-r01#reload in 15
Reload scheduled in 15 minutes by admin on console
Reload reason: Reload Command
Proceed with reload? [confirm]
*Mar  1 03:11:11.659: %SYS-5-SCHEDULED_RELOAD: Reload requested for 03:26:09 UTC Fri Mar 1 2002 at 03:11:09 UTC Fri Mar 1 2002 by admin on console. Reload Reason: Reload Command.

Once everything is configured and connectivity to device was not lost we can cancel reload process.

lab-r01#reload cancel


*Mar  1 03:11:19.415: %SYS-5-SCHEDULED_RELOAD_CANCELLED: Scheduled reload cancelled at 03:11:19 UTC Fri Mar 1 2002

It is very helpful and can save time and rescue from trouble.

Code snippets : Windows : Clear Event Logs


From script repository I did use in the past, VBscript which allows to clear EvenLog on Windows machine. I did use that on computers with Windows XP and Windows Server 2003. however, this script will work also on Windows 7 and Windows server 2008.

By default script clears EventLog on computer where script is executed. To clear logs on remote machine just modify variable strComputer and replace dot with name of the target machine.

Script will read all EvenLog files from machine and will go through them removing all events.

And here is script itself :

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate, (Backup, Security)}!\\" _
& strComputer & "\root\cimv2")
Set colLogFiles = objWMIService.ExecQuery _
("Select * from Win32_NTEventLogFile")
For each objLogfile in colLogFiles
