Port down configuring Private VLAN in 6500

[alexis.fidalgo]

When im tryin to configure private vlans in a 6500 with ios and SUP2/msfc2, we got the ports setted up as isolated to shutdown state and an error saying that there's an incompat between (for example) port 4/25 and port 4/30 in dynamic trunk mode (4/30 is not a trunk, is a vlan member).

This problem is due to the DTP negotiation mismatch. Make sure that the DTP mode is correct.
