About VS : Vlan and tunnel configuration


Where can I see the performance difference between "all VLANs and tunnels" and "enabled on VlanX" on F5?
If there is no difference in performance, then why do I need to specify Vlan? Wouldn't "allow all" be more convenient?

Any help is appreciated.
Thanks !

  • Hi Michaelyang , 
    the difference is "security and managerial" concerns. 
    you’re securing your virtual servers from being accessed by all vlans , so its up to you and based on your needs. 
    if you let it as default , you allow all vlans to access your virtual servers , if you specify vlans , you allow only the selected vlans to access your virtual servers. 
    > but it is best practice to specify your vlans for security and manage your network traffic well.
