Hello *,
regarding PVLANs and the Nexus, my understanding is that we cannot configure Private VLANs on a FEX trunk port with a NX-OS release older than 5.1(3)N2(1) for the Nexus5548... Is there any known workaround for this limitation (appart from performing a SW upgrade)?
Thank you in advance,
Fernando

Hello Fernando,
I would say it all depends of your current architecture (where is the promiscuous port, routing device and so on…).
Maybe you are trying to extend a pvlan domain to an ESX vdswitch or a Nexus 1000v.;
If it is not possible to upgrade to 5.1(3)N2(1) and activate the ‘PVLAN on FEX trunk’ feature, please find some ideas :
Hence those vlans could be allowed on the FEX trunks, they will just be used for the transport of the flows.
The drawback is that we may not connect ‘private-vlan hosts’ on the N5k/N2k (at least in the same pvlan domain).
If there is other alternatives there are welcomed.
Hope that helps.
Best regards.

Hello Karim,
thank you for your answer. Confirms my suspiction. Will have to analyse all the options to see if the current scenario still allows for PVLAN in the end devices...
Thanks and Best regards,
Fernando
