Chapter 47 Configuring Private VLANs
Command
Step 3
Switch(config-if)# switchport mode private-vlan
{host | promiscuous | trunk promiscuous | trunk
[secondary]}
Step 4
Switch(config-if)# [no] switchport private-vlan
mapping [trunk] primary_vlan_ID
{secondary_vlan_list | add secondary_vlan_list}
Step 5
Switch(config-if)# end
Step 6
Switch# show interface port-channel
interface-number switchport
The maximum number of unique PVLAN pairs supported by the switchport private-vlan mapping
Note
command is 1000.
When you configure a Layer 2 Etherchannel as a PVLAN promiscuous port, note the following:
The secondary_vlan_list parameter cannot contain spaces. It can contain multiple comma-separated
•
items. Each item can be a single PVLAN ID or a hyphenated range of PVLAN IDs.
Enter a secondary_vlan_list or use the add keyword with a secondary_vlan_list to map the secondary
•
VLANs to the PVLAN promiscuous port.
• Use the remove keyword with a secondary_vlan_list to clear the mapping between secondary
VLANs and the PVLAN promiscuous port.
This example shows how to configure interface port channel 63 as a PVLAN promiscuous port, map it
to a PVLAN, and verify the configuration:
Switch# configure terminal
Switch(config)# interface port-channel 63
Switch(config-if)# switchport mode private-vlan promiscuous
Switch(config-if)# switchport private-vlan mapping 200 2
Switch(config-if)# end
Switch# show interfaces port-channel 63 switchport

Purpose
Configures a Layer 2 Etherchannel as a
PVLAN promiscuous port.
(Maps the PVLAN promiscuous port to a
primary VLAN and to selected secondary
VLANs.
Exits configuration mode.
Verifies the configuration.
