CirrostratusAbout VS : Vlan and tunnel configuration
Hello,
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.
