...PowerConnect Dell Switch 3348. I need to be able to block ports between ceratin number and i have not been able to find any documentation on how to perform this. if more info needed please let me know.
Huh? Block (disable) certain switch ports? Block TCP or UDP port numbers? Prevent the device plugged into switch port 7 from talking to the device on port 8, although allow it to talk to port 9?
I'm having a bit of trouble parsing your question....
