Configuring a Layer 2 Interface as a PVLAN Host Port
To configure a Layer 2 interface as a PVLAN host port, perform this task:
Command
Purpose
Step 1
Switch# configure terminal
Enters configuration mode.
Step 2
Switch(config)# interface {fastethernet |
gigabitethernet
| tengigabitethernet}
slot/port
Specifies the LAN port to configure.
Step 3
Switch(config-if)# switchport mode private-vlan
{host | promiscuous} | trunk
Configures a Layer 2 interface as a PVLAN host port.
Step 4
Switch(config-if)# [no] switchport private-vlan
host-association
primary_vlan_ID
secondary_vlan_ID
Associates the Layer 2 interface with a PVLAN.
You can use the no keyword to delete all associations
from the primary VLAN.
