I have one stack with two 3750-E and only one switch with IP advanced services license to run OSPF. The second switch still has its original license (IP base). I got from Cisco a license file for the second switch (ip advanced). I have tried the normal procedure to install the license but it is stil not working. I am getting "xml parsing file" error. We ruled out the possibility of a corrupted file.
Is there any specific procedure to apply this license to the second switch while it is on a stack and running? Do I need to separate the stack to apply the license to the second one?
Why do I want that? - in case one fail the other one can handle the OSPF process (high avalability reasons).
