I recently wired my house with CAT6, which allowed me to move all of the connections of my U-Verse Set Top Boxes over to my 3550 switch. Well the other day I was calling my daughter, who was in her room watching TV. She was acting like she didn't hear me. At this point, I used my iPhone to log into the switch, and issued a "shut" on the port going to her room, which killed all network traffic to her room. Lo and behold she magically appeared from her room. I didn't even have to get up out of my seat... LIKE A BOSS!!!
