I looked a bit everywhere and tried to get some info about what is teh difference between SDSL firmware 3.05 vs 3.0.1. Unfortunately I found nothing. Only http://www.ciscopros.info/en/US/prod/collateral/routers/ps221/prod_bulletin0900aecd801d5c4c.html is showing whici IOS is going with which firmware. But nothing is explaining what is the difference between both, what they contain etc etc.. Do i need to contact Cisco for that or do I need to open a TAC?
Your help is very much appreciated
