Protect Ports at SWitches

- Example

   WwW protected-port ---- DMZ ---- unprotect-port [Router] --- ProtectPort Mail

Q: How I Enable it?
A: SW(config)# int fx/y
   SW(config-if)# switchport protected

protected-port <--> protected-port == not-allowed
protected-port <--> unprotected-port == allowed
unprotected-port <--> unprotected-port == allowed (default)

The protected port is pretty neat and as you have
seen very easy to configure however it is very limited.
