switchport protected (Interface Config)
Use this command to add the selected interface to a protected port group. You can only configure an
interface as protected in one group.
Note:
Port protection occurs within a single switch. Protected port configuration does not
affect traffic between ports on two different switches. No traffic forwarding is possible
between two protected ports.
[no] switchport protected
Use the no switchport protected command to configure the selected port as unprotected. The
groupid parameter identifies the set of protected ports to which this interface is assigned.

Note: The VLAN-Stacking feature was not tested in SFTOS 2.5.1 or 2.5.2, so the
commands in this section are not supported, as noted in the Command History of each
command.
