I know Jack since I came to work for Cisco in year 2000 to support WCOM DNE lab. At that time I don’t know Jack too well.
But after I came back to work for Cisco again in year 2013, I had the honor to work and interface with Jack a whole lot more.
Jack has been a great mentor to me. Over the years, he has always treated me as a part of his team and put me under his wings. We can chat almost about everything and anything beside business. We shared family stories, vacation pictures, religion and personal values.
He is a great friend I will miss dearly.
