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.
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.
switchport protected (Global Config)
Use this command to create a protected port group. The
<groupid>
parameter identifies the set
of protected ports. Use the
name <name>
pair to assign a name to the protected port group. The
name can be up to 32 alphanumeric characters long, including blanks. The default is blank.
NOTE:
Port protection occurs within a single switch. Protected port configuration
does not affect traffic between ports on two different switches. No traffic for-
warding is possible between two protected ports.
Default unprotected
