Protected Port
5.2.4.3
There are two protected port groups. Ports in different groups can't communicate each other.
In the same group, protected ports can't communicate each other, but can communicate with unprotected ports. Unprotected
ports can communicate with any ports, including protected ports. In default, all ports are in Group1 and not protected.
For example, in the above configuration page for protected port, Port4 in Group2, other ports in Group1, and both Port1& Port2
are protected. These settings provide Port4 can't communicate with other ports in Group1. Port1 & Port2 can't communicate
each other but can communicate with other ports in Group1.
