Permitting Routing of Secondary VLAN Ingress Traffic
Note
Isolated and community VLANs are both called secondary VLANs.
To permit routing of secondary VLAN ingress traffic, perform this task:
When you permit routing on the secondary VLAN ingress traffic, note the following:
The private-vlan mapping interface configuration command only affects private VLAN ingress 
traffic that is Layer 3 switched. 
The secondary_vlan_list parameter cannot contain spaces. It can contain multiple comma-separated 
items. Each item can be a single private VLAN ID or a hyphenated range of private VLAN IDs.
Enter a secondary_vlan_list parameter or use the add keyword with a secondary_vlan_list 
parameter to map the secondary VLANs to the primary VLAN.
Use the remove keyword with a secondary_vlan_list parameter to clear the mapping between 
secondary VLANs and the primary VLAN.
Command
Purpose
Step 1
Switch# configure terminal 
Enters global configuration mode.
Step 2
Switch(config)# interface vlan 
primary_vlan_ID 
Enters interface configuration mode for the primary 
VLAN.
Step 3
Switch(config-if)# [noprivate-vlan mapping 
primary_vlan_ID {secondary_vlan_list | add 
secondary_vlan_list | remove secondary_vlan_list}
To permit routing on the secondary VLAN ingress traffic, 
map the secondary VLAN to the primary VLAN. 
You can use the no keyword to delete all associations 
from the primary VLAN.
Step 4
Switch(config-if)# end 
Exits configuration mode.
Step 5
Switch# show interface private-vlan mapping 
Verifies the configuration.
