We have a 2811 router. Using nearly all functions (VPN, CME, Firewall etc).
The flash is almost full, now using 12.4v3 IOS. I have to upgrade it to be able to use AnyConnect VPN and is thinking about ereasing all of the flash. However, what files will I need to add again?
I understand I will have to add the IOS bin file of course. Then I will need to add the SDM software (I assume I can let the setup.exe file solve what files to transfer). Then what about the "cme-basic-126.96.36.199.tar" file? This is one I can extract on the router, but do I need to? And if I need to - I assume I should erease the tar-file afterwards to save space.
I think I would have to load bin-files for our Cisco IP Phones too... or is that included in the cme-basic.tar file?
So far I have just upgaded the IOS bin file some times. On my last upgrade attemt I was out of space. The bin-files just get bigger for each new version. What can I do about that? Is there a way to get a bigger flash?
Many questions here, but if someone can help me out on parts if this it would be great!
