Hi guys,
I am trying to share two vlans in two different contexts but when I try to add the same vlan in the second context I receive this message: “Interface Vlan15 cannot be allocated to context. Interface is allocated to another context in a different failover group”. I have seen same example where you can share the same vlans; so I don’t know where is my fail.

thanks.

Correct.
Move both failover groups to one blade so, they both show active on one blade.
Now, move the context A(previous one) to a diff. failover group. Now, you can add the vlan to context B which will also be in the same failover group.

I believe you are using active/active failover.
If that is the case then the context that you are creating should also belong in the same failover group as you are trying to share a vlan between contexts that is in a diff. failover group.
Both contexts that share a vlan should belong in the same failover group. I believe that is the problem.

Thanks for your answer, Kusankar.
You are right; the contexts are in different failover group. Is it not possible to share the same interface vlan then?
