I am upgrading the image for the 4500 and last time that I did it, it didn't go well, actually it was a mess. So this time I want it to be smooth, hopefully. I went to cisco.com and got a hand-out on upgrading the switch for 4500 switch. But I am not sure if it would work or not. I need you advice.
#boot system flash:image
#copy run start
#redundancy reload peer
My question, do I have to do all of these steps to upgrade the software?
IME, you don't need all those steps to upgrade the IOS... here's how I generally go about it.
First, load new IOS into memory or onto flash card (my preferred method) from tftp server. Once the software is on one of the flash cards, I then copy it over to the redundant sup flash card. After that copy, I change the boot statement in the config to point to the new software. When you save the config, it will automatically update the config for the redundant sup. If you forget to copy the software to the redundant sup, you will get an error message when the auto-copy tries to sync the two sups. Then, once the new boot statement is in, simply force a switch-over to the redundant sup so it reboots the first sup, then force it back once the first one is done rebooting and the second one will reboot. Now both will be on new IOS. Done.
It's pretty simple, but you must remember to copy the new IOS to the redundant sup!
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
