Cisco Systems EA6500 Manual De Usuario

Because the private VLAN port sticky ARP entries do not age out, you must manually remove 
private VLAN port ARP entries if a MAC address changes. You can add or remove private VLAN 
ARP entries manually as follows:

Router(config)# no arp 11.1.3.30 

IP ARP:Deleting Sticky ARP entry 11.1.3.30

Router(config)# arp 11.1.3.30 0000.5403.2356 arpa 

IP ARP:Overwriting Sticky ARP entry 11.1.3.30, hw:00d0.bb09.266e by hw:0000.5403.2356

These sections describe how to configure private VLANs:

If the VLAN is not defined already, the private VLAN configuration process defines it.

With Release 12.1(11b)E and later, when you are in configuration mode you can enter EXEC mode-level 
commands by entering the do keyword before the EXEC mode-level command.

To configure a VLAN as a private VLAN, perform this task:

This example shows how to configure VLAN 202 as a primary VLAN and verify the configuration:

Router# configure terminal 

Router(config)# vlan 202 

Router(config-vlan)# private-vlan primary 

Router(config-vlan)# end 

Router# show vlan private-vlan 

Router(config)# vlan vlan_ID 

Enters VLAN configuration submode.

Router(config-vlan)# private-vlan {community | 

 | primary}

Configures a VLAN as a private VLAN. 

Router(config-vlan)# no private-vlan {community | 

 | primary}

Clears the private VLAN configuration. 

These commands do not take effect until you exit 
VLAN configuration submode.

Router(config-vlan)# end 

Exits configuration mode.

Router# show vlan private-vlan [type] 

Verifies the configuration.
