ACE design / implementation / GNU

Filed under: Bridging + Switching,module types — ocsic @ 19:20

Most difficult thing is to implement the device into the customer network. This needs a lot of planning and discussions about the design and how it should be implemented.

The logic is, that you will mostly try to implement the ACE in between. From one VLAN into the other. The ACE will provide for VIP and VLAN interfaces to be the gateway for traffic back to the clients. Even bypassing the ACE is possible. This should be planned before and it should be clear at what point the device will be implemented.  It might be a good idea to have a good look at grown network struktures. While implementing the ACE it all depends on good understanding of te traffic flow and the current network infrastructure. The best is to communicate possible problems and catches.
