1000v PVLAN not supported?

[Petr Nagernyuk]

The problem is I can't use PVLAN on my Cisco Nexus 1000v. The CLI says "invalid command".

Version of Cisco Nexus1000v used - 4.2.(1)SV1(4).

What can be the problem? Should I use an earlier version?

Thank you!!!

Hi Petr,

We do fully support PVLANs on Nexus 1000v.

Here is the URL to configuration guide for PVLANs for version 1.4:

Hope this helps!

Hi, Abbharga! Thank you for the fast answer!

No doubt, that version 1.4 do support PVLAN. But what about my screenshots? As you can see, when I try to issue the "private-vlan primary" in the vlan configuration mode, the CLI answers: "...invalid command..."

Hi Petr,

By default the private-vlan feature on 1.4 new install is disabled.

You can turn on the feature by using the command "feature private-vlan". You can check the enabled / disabled features using the command "show feature".

Once you have the feature enabled, you should be able to configure it.

I looked the document again and seems like this is missing in the document. I will look at the document again and if needed will open up a request to correct it.

Hi Petr,

I believe you have to enable the feature called "private-vlan" first.

eg:

Nexus1000V(config)# vlan 10 
Nexus1000V(config-vlan)# private-vlan primary
                         ^
% Invalid command at '^' marker.
Nexus1000V(config-vlan)# exit
Nexus1000V(config)# feature private-vlan 
Nexus1000V(config)# vlan 20
Nexus1000V(config-vlan)# private-vlan isolated 
Nexus1000V(config-vlan)# exit
Nexus1000V(config)# vlan 10
Nexus1000V(config-vlan)# private-vlan primary 
Nexus1000V(config-vlan)# private-vlan association 20
Nexus1000V(config-vlan)# end

Nexus1000V# sh vlan private-vlan 
Primary  Secondary  Type             Ports 
-------  ---------  ---------------  -----------------
10       20         isolated

Wow, that's it! Thank you gentlemen, that was the decision:

(config)# feature private-vlan

This command is really absent in the given link

Thanks once again!

Hi Petr,

Just as an update, I had opened the documentation bug for the update. The documents have been updated for the feature option.
