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?
