3.6 CONFIGURING PROTECTED PORTS
The Protected Port feature is used to prevent ports from forwarding traffic to each other, even when
they are on the same VLAN. Ports may be designated as either protected or unprotected. Ports are
unprotected by default. Multiple groups of protected ports are supported.
3.6.1 Protected Port Operation
Ports that are configured to be protected cannot forward traffic to other protected ports in the same
group, regardless of having the same VLAN membership. However, protected ports can forward
traffic to ports which are unprotected (not listed in any group). Protected ports can also forward
traffic to protected ports in a different group, if they are in the same VLAN. Unprotected ports can
forward traffic to both protected and unprotected ports. A port may belong to only one group of
protected ports.
This feature only applies to ports within a switch. It does not apply across multiple switches in a
network.
