Upgrading a 6500 is pretty straight forward, provided the necessary is done in the right order. I’ve listed the steps I would typically take to fully upgrade a single Cisco-6509-E (single Route-Processor) with a IPSEC VPN SPA blade.
Please lab this if possible BEFORE trying it in a production network. I have illustrated the steps to be taken if some of the known funnies occur during an upgrade. Feel free to use this as a guideline.
Firstly download the IOS and image versions, you need. Obviously do a little homework and check the specific IOS for known bugs using the Bug Toolkit. Don’t just pick any IOS. Make sure all the required features are relatively bug free.
Copy the downloaded files to the following locations:
- ROMMON firmware to sup-bootflash
- BOOTLDR to bootflash
- IOS to flash disk
I always use FTP if possible, due to the higher transfer rates. 10.3.29.239 is connected to the switch and is running a FTP server, expecting a username:password of cisco:pass.
