Figure 47-1
Note Dynamic addresses secured on an isolated private VLAN host port on private VLANs are secured on the
secondary VLANs, and not primary VLANs.
To configure port security on an isolated private VLAN host port, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# vlan sec_vlan_id
Step 3
Switch(config-vlan)# private-vlan isolated
Step 4
Switch(config-vlan)# exit
Step 5
Switch(config)# vlan pri_vlan_id
Step 6
Switch(config-vlan)# private-vlan primary
Step 7
Switch(config-vlan)# private-vlan association
add sec_vlan_id
Step 8
Switch(config-vlan)# exit
Step 9
Switch(config)# interface interface_id
Step 10
Switch(config-if)# switchport mode private-vlan
host
Step 11
Switch(config-if)# switchport private-vlan
host-association primary_vlan secondary_vlan
Step 12
Switch(config-if)# [no] switchport port-security
Step 13
Switch(config-if)# end
Step 14
Switch# show port-security address
interface interface_id
Switch# show port-security address
