[no] ip local-proxy-arp Note: Even after ip-local-proxy-arp is disabled (no ip-local-proxy-arp) in a secondary VLAN, Layer 3 communication may happen between some secondary VLAN hosts, until the ARP timeout happens on those secondary VLAN hosts. [no] private-vlan mode {community | isolated | primary} [no] private-vlan mapping secondary-vlan vlan-list show interfaces private-vlan [interface interface] show vlan private-vlan [community | interface | isolated | primary | primary_vlan | interface interface] show vlan private-vlan mapping Set the PVLAN mode of the selected port. switchport mode private-vlan {host | promiscuous | trunk} Command Mode INTERFACE VLAN INTERFACE VLAN INTERFACE VLAN EXEC EXEC Privilege EXEC EXEC Privilege EXEC EXEC Privilege INTERFACE Note: Secondary VLANs are Layer 2 VLANs, so even if they are operationally down while primary VLANs are operationally up, Layer 3 traffic will still be transmitted across secondary VLANs.
