I have defined a trunk between a nexus 5k and cat 3750 as a pvlan trunk - now I would like to add redundance and performance and tried to establish a vpc between my par of nexus's and the 3750 stack - but the nexus tell me that the port-channel doesn't support pvlan's - and then - ehh - do I get any benefits of running the trunk as a pvlan trunk at all?
btw - we have a vmware environment whereto the interfaces in the nexus 5020 are trunk ports up to the esxhosts (10G pass-through modules in Dell Blade Servers) - can I mix both std trunk here and a pvlan trunk ? the vswitch up in the vmware environment isn't Private VLAN avare so it would make sense the define the pvlan part of the trunk as a promiscous pvlan so that the secondary vlan is mapped into the primary vlan - - can I have a mix of pvlan trunk and std trunk on the same interface?
As far as my knowledge goes, a port can be either a standard trunk or a special PVLAN trunk. It cannot be both. The documentation appear to confirm this, as the particular operating mode of a port is configured using the switchport mode command, and you can not have a port operating in two modes simultaneously (there cannot be two conflicting switchport mode commands on the same interface).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
