I have a 4006, with two ports that have no color lit on the LED (no green, no orange). I perform a 'shut', no change. 'no shut', no change. So, I'm trying to figure out 1. what's wrong, and 2. if there's a way I can basically reset that port. I've found the clear interface command, which says it "resets the hardware logic". Given that that's not exactly a detailed description, I'm hesitant to do it. Any ideas? Thanks, Kevin
