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.
Yep, it and Feature Navigator are where you want to be.
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?
12.4 is only recomended in limited deployment. 12.3(x) mainline is for
general deployment.
Cisco is pretty conservative for their software recomendations.
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?
Yes, newer and newer images require huge amounts of more memory.
Its not necessarily Flash that is limited, but also DRAM in the box.
12.4 probably requires maxing out your 3640 in DRAM for most feature sets.
Looks like IP only gets away with *only* 64M of DRAM installed.. :)
Some early 3640's probably shipped with 16M of DRAM and 4M of Flash....
Thanks Doug,
but what about this warning about the flash? Do you think I have 32MB
flash and it's just not reporting correct in the "sh ver"?
