Virtual Wire TAG Allowed vs VLAN Subinterfaces
Hello good morning, here again to ask some questions and review some doubts, thank you very much for the collaboration and good will as always.
In relation to the use of Virtual Wire, what is the reason to use, in VLAN environments, what is the reason or advantage and/or disadvantage at vmware level to use for the vlan TAG, the Tag Allowed option vs. use Subinterfaces layer 2 and set them there each TAG ?
What is the advantage, disadvantage and/or in which situations to opt for one or the other option ?
Thanks, I remain attentive, greetings and attentive to your comments,
Excellent Reaper, good afternoon, thank you very much for the clarification, best regards
tag allowed simply allows a certain vlan .1Q through the vwire. the same zones will be applied to all .1Q tags frowing through the vwire
by adding subinterfaces, you can apply more controls (different zones/rules/...)
no real disadvantages to using one or the other, it just depends on your needs (do you need multiple zones because all the vlans are 'different' state of cleanliness like internal, external, dmz, ..., or are they all the same (internal spanning) and you just need to perform L7 inspection)
