You can try to report it to HR or the Ethics Committee as @zkb+1nUn7N7T said, but don't expect anything to happen except for your life/work environment to get worse. I won't say that Cisco management and/or HR will retaliate against you, but they will make your life he-l.
I had a great manager who finally got fed up and quit. Everyone under this manager rolled up to his boss until a replacement manager could be found. The higher level manger, I don't remember their title at the time, but it was a year before they were promoted to Director, said that he was "too busy to have 1:1's with all of us now that there were so many reporting to him and that only if we had issues, should we schedule time with him."
Suddenly, at my end of year performance review, I went from a history of above average reviews and a mid-year review of above average to bottom 5% under the skip level manager. When I commented to him that I had expected him to give me the same courtesy of contacting me if he had issues and that no news was good news, I didn't understand how I could have slipped from above average to the worst rating possible with zero feedback and I didn't know how to communicate with him.
The next thing I know, he's reported me to HR and they scheduled a mediated session between him and I with HR to discuss how I would email him in great detail so that he could prioritize when to read my emails based on the guidance provided in that session. Shortly thereafter, a new manager was hired, I was on the sh-t list and the new manager put me on a performance improvement plan and basically worked to manage my butt out of Cisco until the 2011 WFR was announced and then all was great and the PIP was done and I was LR'd a couple of months later. Because I was on the PIP, I was blocked from doing an internal transfer to get out from under that manager and the skip level manager who started the cr-p.
I was able to return not long after the LR blackout period to a much better team and it's been pretty good. Above average IPF's every year and great feedback since they no longer do official performance reviews.
My recommendation to you, look for an internal transfer or just leave Cisco altogether. Trying to outlast a cr-ppy manager will only make you unhappy.
