Description: FCoE provides increased flexibility, but with this flexibility new challenges arise in assuring highly robust Fabrics. The FCF does not have the complete control that a Fibre Channel switch has. Ethernet bridges commonly provide a feature called Access Control Lists (ACLs). Properly configured ACLs may emulate a point-to-point link by providing the traffic enforcement previously discussed. Furthermore, the FIP protocol has been designed to enable Ethernet bridges to efficiently monitor FIP frames passing through them. This data facilitates the automatic configuration of these ACLs. In addition, the automatic configuration is possible independent of any other ACLs that may be in use in the network for other applications. And FIP Snooping is to maintain these ACLs.
