This section describes the commands you use to configure provisioning (IEEE 802.1p,) which allows you to prioritize ports.
vlan port priority all
This command configures the port priority assigned for untagged packets for all ports presently plugged into the device. The
range for the priority is 0-7. Any subsequent per port configuration will override this configuration setting.
vlan priority
This command configures the default 802.1p port priority assigned for untagged packets for a specific interface. The range
for the priority is 0–7.

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.

Default 0
Format

Mode Interface Config
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.
