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
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface port-channel
interface-number
Step 3
Switch(config-if)# switchport mode private-vlan
{host | promiscuous | trunk promiscuous | trunk
[secondary]}
Step 4
Switch(config-if)# [no] switchport private-vlan
association trunk primary_vlanb_ID
secondary_vlan_ID
Step 5
Switch(config-if)# [no] switchport private-vlan
trunk allowed vlan vlan_list [all | none | [add
| remove | except] vlan_atom [,vlan_atom...]
Step 6
Switch(config-if)# switchport private-vlan
trunk native vlan vlan_id
Step 7
Switch(config-if)# end
Step 8
Switch# show interfaces Port-channel
interface-number switchport

Purpose
Enters global configuration mode.
Specifies the LAN interface to configure.
Configures a Layer 2 Etherchannel as a
PVLAN trunk port.
(Configures association between primary
VLANs and secondary VLANs the PVLAN
trunk port with a PVLAN.
Note
You can use the no keyword to delete all
associations from the primary VLAN.
(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.
(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.)
Exits configuration mode.
Verifies the configuration.

Configuring PVLANs
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.
