The switchport protected interface configuration command overrides the FDB decision and sends
all Unicast, Multicast and Broadcast traffic to an uplink port. To disable overriding the FDB
decision, use the
no form of this command.
Syntax
switchport protected {ethernet port | port-channel port-channel-number }
no switchport protected

Default Configuration

Command Mode

User Guidelines
Private VLAN Edge (PVE) supports private communication by isolating PVE-defined ports
and ensuring that all Unicast, Broadcast and Multicast traffic from those ports is only
forwarded to uplink port(s).
PVE requires only one VLAN on each device but not on every port; this reduces the number
of VLANs required by the device. Private VLANs and the default VLAN can function
simultaneously in the same device.
Example
The following example configures ethernet port g8 as a protected port, so that all traffic is sent to
its uplink (ethernet port g9).
Console (config)# interface ethernet g8
Console (config-if)# switchport forbidden vlan add 234-256
Console (config) # interface ethernet g9
Console (config-if) # switchport protected ethernet g8
