Based on the exhibit, what does the "X" represent in the FCIP tunnel configuration?

In the context of FCIP (Fibre Channel over IP) tunnel configurations, a VE_port (Virtual E_port) is used to create a virtual link between two switches over an IP network. This virtual link allows for the extension of Fibre Channel fabrics across geographically dispersed locations. The VE_port functions similarly to an E_port but operates over an IP network, enabling the transport of Fibre Channel frames over long distances.References: Dell Information Storage and Management V5, FCIP Tunnel Configuration,Dell Certification Resource
