Upgrading an 881

[gavin]

Forgive me if this is a stupid question but I am a Cisco newbie!

I am managing a Cisco 881 with Adv Ip Services ( CISCO881-SEC-K9)

It has IOS 15.0(1) M8 on it. I see that there is a new IOS version 15.2M&T that (I think is applicable), and I have read the upgrade procedures for upgrade via USB and TFT.

If I install it will my licence for Adv Ip Services be preserved or overwritten. And if the latter, do I need to export it and reapply it? If so, what is the process?

Thanks very much

Gavin

Hi,

why update the IOS if you are happy with current version ?

Hi Alain

Thanks for your reply. My understanding is that it contains some fixes for security vulnerabilities which is my reason for looking at upgrade.

Check that 'secuirty vulnerabilities' often are corner cases not applicable to every situation.
