Can you get the router to boot from the tftp server before fiddling with the flash? Then you can fiddle with the flash and if you blow it then you get another shot... I'm also a big fan of "reload in 60".
Here are my handy dandy remote router tips. #1. handy-dandiest tool in the universe. A 28.8k baud line powered pocket modem jumpered to only connect at 9600 baud with a 50 foot phone cord and a cable to connect it to the CONSOLE port.... (Instructions to non-tech user: Connect the big end to your router's console port. Unplug your fax machines phone line and plug the phone cord into it. What is your fax number?) #2. Reload in 60 #3. copy running-config flash:old-config #4. Copy runn-start --- Copy tftp flash:newconfig --- reload in 5 --- copy flash:newconfig running-config ... (If your newconfig doesn't work, then reboot back to the old config in 5 minutes.) Anybody got any others? -----Original Message----- From: Tony Medeiros [mailto:[EMAIL PROTECTED]] Sent: Friday, March 01, 2002 9:47 AM To: [EMAIL PROTECTED] Subject: Re: Problem of upgrading IOS for a router at remote site [7:36966] Never ??? Thats a hard call when unless your company has lots of free frequent flyer miles. There are ways to make sure you don't blow it. 1. Test your new image on a router with simular hardware configuration if possible. That way you don't boot it on an incompatable OS. 2. If you have the room in flash, keep the old image. 3." line vty 0 4" "no exec-timeout" This will keep you telnet session alive. Or, hit the space bar once in while to keep it from timing out I have upgraded remotely many times and never blown it. However, it isn't without risk. I always cross my fingers !!
