IOS upgrade problem

Has anybody faced problems of link performance after upgrading flash,

dram memory and IOS? Does it make sense? Considering that I have the

minimum requirements to run the new IOS version?


Re: IOS upgrade problem

It depends. There could be some incompatibility or caveat with the IOS you upgraded to, that might be causing this. What IOS are you running and what hardware do you got. Can you paste a sh version ?

Thisisshanky, it is an enterprise version. I have compared with the old version using feature navigator and it seems to be compatible.

Re: IOS upgrade problem

How can I check if there is some caveat with this particular version?

I don´t have access to bug tool kit.

Hi muca,

You can check out this link if the IOS version you are using has deferral notices associated with it.
