I had a quick question. When you configure "switchport protected" does this not forward traffic from other switches to this port as well as ports on the local switch?
The issue is this, we have students that like to play LAN games during school hours. Protected port seems ideal in the sense that it does not allow other protected ports from talking to each other. This seems straight forward on one switch but if you have multiple switches, will a protected port on one switch be denied from talking to a protected port on another switch?
>> will a protected port on one switch be denied from talking to a protected port on another switch?
Unfortunately this is not true : the switch uplinks are primary/promiscuous ports so the risk is to allow traffic between ports in different access layer switches
Hope to help
