Bio

Almost twenty years of experience with Cisco products. The first IOS I learned was version 9, the first routers were mostly 2500 series. IPX was more in use than IP and 10MB ethernet over coax was not uncommon. But networking technology has come a long way since those days.
In 1999 I started my own company in the networking business and we are a cisco partner since then.
Like to read and solve problems on the forum simply because it's fun. Besides, reading about other people's approach and insights raises your personal level of skill.
