private-vlan trunk promiscuous

lalain

Hello,

I would like to configure a "private-vlan trunk promiscuous" on a 4500 and I would like to connect the trunk to a PIX firewall. So the PIX will have multiple VLANs interfaces and each of these interfaces will be the layer 3 interface of a primary-vlan.

I think that it is possible with the version 12.2.(31) SG but I can not succeed to configure it. How do you specify which primary vlan is allowed in the trunk ?

Regards,

Alain.

When you configure a Layer 2 interface as a PVLAN promiscuous port note that secondary_vlan_list parameter cannot contain spaces.Refer the following URL for more information

Hello,

I have found the solution, it is:

<--

vlan 350

private-vlan primary

private-vlan association 351

!

vlan 351

private-vlan isolated

!

vlan 367

private-vlan primary

private-vlan association 368

!

vlan 368

private-vlan isolated

!

interface GigabitEthernet3/9

switchport private-vlan trunk allowed vlan 1,350,367

switchport private-vlan mapping trunk 350 351

switchport private-vlan mapping trunk 367 368

switchport mode private-vlan trunk promiscuous

!

Alain.
