Re: PVLAN on 3750

I assume it should be able to do that... show interface switchport has the
following field (they are not configured now but assuming they can be):

Administrative private-vlan host-association: none
Administrative private-vlan mapping: none
Administrative private-vlan trunk native VLAN: none
Administrative private-vlan trunk Native VLAN tagging: enabled
Administrative private-vlan trunk encapsulation: dot1q
Administrative private-vlan trunk normal VLANs: none
Administrative private-vlan trunk associations: none
Administrative private-vlan trunk mappings: none

Any documentation that can validate it not being available on the 3750?
Really cannot find it anywhere... :/
