So I setup 3 different contexts. I am wanting to configure the same vlan id, on each of these contexts. An error comes up displaying, this vlan is already used on port such n such. If each context is it's on firewall, why does it give this error? Can anyone assist with a design configuration for this. Thanks

Also we can see some discussions around this:
