Hi folks,

I am about to go through a major upgrade program in my company as per
other posts. I've been crawling the cisco website to find tools that
may help me doing this. I've cam accross a tool called the "Software
Advisor", it's pretty cool but I have some questions about it that I
hope some of you may help me with.

I use the "find software compatible with my hardware", I then select
"Enter your hardware configuration using show command output from your
device", I copy and paste my "sh ver" and "sh diag", it then tells me
a version of software for my device. Now is this the "recommended"
software I should use as it's "Compatible" with my hardware, as long
as it doesn't contain any bugs (that I care about) or lacks features
that I need? So can I use this for setting baseline software versions
for my hardware?

Why does a 3640 only get recommended a 12.3(17c) version of software
and not 12.4?

After I ran the advisor on one of my devices it gave me a couple of
differnet versions of software, I then get the message "This image
requires more memory than currently (as per show version) installed on
your device. If you select this image, please upgrade your memory
before upgrading to it" The "show version" shows "31360K bytes of ATA
System CompactFlash (Read/Write)" which is equivilant of 30.625MB. The
minimum flash is 32MB, for the selected image, do I not have 32MB?

thanks folks
Dave


Be careful with these recommendations.

Cisco will try to always recommend the latest release which of course
requires the most memory, etc, etc

You may have no need for any of the features in the recommended
release.

BTW all of these new features have TONS of bugs which may also impact
base functionality.


In the "old" days one could usual pick a GD realease (General
Deployment) and be done with it; those days are long gone...

I have witnessed many a network engineer impaling themselves by going
with the latest and greatest IOS release.

Just consider how painful it will be to back out a faulty release once
you have implemented it one 50 or 100 routers
