PVLAN trunk on FEX

[anazarenko]

Dear All,

Maybe somebody from Cisco can shed some light if  the PVLAN trunk support on FEX ports is at least on the roadmap?

The Nexus 1000v and VmwareDV switches become more and more deployed  on the servers with virtualization  and it's a pity that such servers can't be plugged straight into FEX ports in case they are extending the DC PVLANs.

Deal All,

I found the following feature:

system private-vlan fex trunk

You must disable all the FEX isolated trunk ports before configuring PVLANs on the FEX trunk ports.
If the FEX isolated trunk ports and the FEX trunk ports are both enabled, unwanted network traffic might
occur.

Can anybody elaborate this statement? Does it mean isolated trunk and extension trunk can not coincide on different FEX ports at all or I can enable my isolated trunk ports  back after enabling this feature?

Or maybe Cisco just means that extension trunk and isolated trunk can't be configured on the SAME port?
