Use the show vlan private-vlan or the show interface status privileged EXEC command to display
primary and secondary VLANs and private-VLAN ports on the switch.

Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface
If the private VLAN will be used for inter-VLAN routing, you configure an SVI for the primary VLAN
and map secondary VLANs to the SVI.
and map secondary VLANs to the SVI.
Note
Isolated and community VLANs are both secondary VLANs.
Beginning in privileged EXEC mode, follow these steps to map secondary VLANs to the SVI of a
primary VLAN to allow Layer 3 switching of private-VLAN traffic:

This example shows how to map the interfaces of VLANs 501 and 502 to primary VLAN 10, which
permits routing of secondary VLAN ingress traffic from private VLANs 501 to 502:
