Protected Ports Commands
This section describes commands you use to configure and view protected ports on a switch.
Protected ports do not forward traffic to each other, even if they are on the same VLAN.
However, protected ports can forward traffic to all unprotected ports in their group.
Unprotected ports can forward traffic to both protected and unprotected ports. Ports are
unprotected by default.

Unprotected ports can forward traffic to both protected and unprotected ports. Ports are
unprotected by default.
If an interface is configured as a protected port, and you add that interface to a Port Channel
or Link Aggregation Group (LAG), the protected port status becomes operationally disabled
on the interface, and the interface follows the configuration of the LAG port. However, the
protected port configuration for the interface remains unchanged. Once the interface is no
longer a member of a LAG, the current configuration for that interface automatically becomes
effective.
