PVLAN commands
ip local-proxy-arp
Enables the local proxy Address Resolution Protocol (ARP) on an interface.
Syntax
ip local-proxy-arp
Parameters None
Default Not applicable
Command Mode VLAN INTERFACE CONFIGURATION
Usage
Information
The router responds to ARP requests for addresses that are on the same subnetwork of that
interface.
This command is applicable only for the primary VLAN.
Ensure that you configure an IPv4 address on the primary VLAN before you enable local proxy ARP.
In a VLT setup, you must configure this command on both the primary and secondary VLT nodes. The
secondary VLT node suppresses the local proxy ARP functionality.
The no form of this command disables the local proxy ARP functionality.
ExampleTo
enable local
proxy ARP in a
VLAN.
OS10(conf-if-vl-10)# ip local-proxy-arp
Supported
Releases
10.5.2.0 or later
private-vlan mapping secondary-vlans
Maps a list of secondary VLANs to the primary VLAN.
Syntax
private-vlan mapping secondary-vlans vlan-list
Parameters vlan-listList of secondary VLANs to map to the primary VLAN.
Default Regular VLAN
Command Mode VLAN INTERFACE CONFIGURATION
Usage
Information
This command is applicable only for the primary VLAN.
This command maps a list of secondary VLANs to a primary VLAN. Before you map the secondary
VLANs to the primary VLAN, create the secondary VLANs and configure PVLAN mode as secondary.
If the secondary VLANs are not created when you map them to a primary VLAN, this configuration
takes effect only after you create the secondary VLANs.
The no form of this command removes the mapping of the secondary VLANs to the primary VLAN.
ExampleTo
map secondary
VLANs 20 and 50
to the primary
VLAN 10.
OS10(conf-if-vl-10)# private-vlan mapping secondary-vlans 20, 50
Supported
Releases
