Chapter 47      Configuring Private VLANs
Configuring PVLANs
Configuring a Layer 2 EtherChannel as an Isolated PVLAN Trunk Port
To configure a Layer 2 EtherChannel as an isolated 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 trunk port.
Step 4
Switch(config-if)# [no] switchport private-vlan 
association trunk primary_vlanb_ID 
secondary_vlan_ID
(Configures association between primary 
VLANs and secondary VLANs the PVLAN 
trunk port with a PVLAN.
Note Multiple PVLAN pairs can be 
specified using this command so that 
a PVLAN trunk port can carry 
multiple secondary VLANs. If an 
association is specified for the 
existing primary VLAN, the existing 
association is replaced. If there is no 
trunk association, any packets 
received on secondary VLANs are 
dropped.
You can use the no keyword to delete all 
associations from the primary VLAN.
Step 5
Switch(config-if)# [no] switchport private-vlan 
trunk allowed vlan vlan_list [all | none | [add 
| remove | except] vlan_atom [,vlan_atom...]
(Configures a list of allowed normal VLANs 
on a PVLAN trunk port
You can use the no keyword to remove all 
allowed normal VLANs on a PVLAN trunk 
port.
Step 6
Switch(config-if)# switchport private-vlan 
trunk native vlan vlan_id
(Configures a VLAN to which untagged 
packets (as in IEEE 802.1Q tagging) are 
assigned on a PVLAN trunk port.
If there no native VLAN is configured, all 
untagged packets are dropped.
If the native VLAN is a secondary VLAN and 
the port does not have the association for the 
secondary VLAN, the untagged packets are 
dropped.
You can use the no keyword to remove all 
native VLANs on a PVLAN trunk port.)
Step 7
Switch(config-if)# end
Exits configuration mode.
Step 8
Switch# show interfaces Port-channel 
interface-number switchport 
Verifies the configuration.
