Configuring PVLANs
This example shows how to configure interface port channel 63 as a secondary trunk port, and to verify
the configuration:
Switch# configure terminal
Switch(config)# interface port-channel 63
Switch(config-if)# switchport mode private-vlan trunk secondary
Switch(config-if)# switchport private-vlan trunk native vlan 10
Switch(config-if)# switchport private-vlan trunk allowed vlan 10. 3-4
Switch(config-if)# switchport private-vlan association trunk 3 301
Switch(config-if)# end
Switch# show interfaces port-channel 63 switchport

Configuring a Layer 2 Etherchannel as a Promiscuous PVLAN Trunk Port
To configure a Layer 2 Etherchannel as a promiscuous PVLAN trunk port, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface port-channel
interface-number
Specifies the LAN interface to configure.
Step 3
Switch(config-if)# switchport mode private-vlan
{host | promiscuous | trunk promiscuous | trunk
[secondary]}
Configures a Layer 2 Etherchannel as a
PVLAN promiscuous trunk port.
Step 4
Switch(config-if)# [no] switchport private-vlan
mapping [trunk] primary_vlan_ID
{secondary_vlan_list | add secondary_vlan_list
| remove secondary_vlan_list}
Maps the promiscuous PVLAN port to a
primary VLAN and to the selected secondary
VLANs.
This command offers 3 levels of removal.
