Which of the following FIP components operates on the native VLAN?

  • FLOGI
  • FIP VLAN discovery
  • FIP FCF Discovery
  • FDISC
Explanation:

Of the available choices, only FCoE Initialization Protocol (FIP) virtual local area network (VLAN) Discovery operates on the native VLAN. FIP VLAN Discovery is one of two discovery protocols used by FIP during the Fibre Channel over Ethernet (FCoE) initialization process. FIP itself is a control protocol that is used to create and maintain links between FCoE device pairs, such as FCoE nodes (ENodes) and Fibre Channel Forwarders (FCFs). ENodes are FCoE entities that are similar to host bus adapters (HBAs) in native Fibre Channel (FC) networks. FCFs, on the other hand, are FCoE entities that are similar to FC switches in native FC networks.
FIP VLAN Discovery is typically the first discovery process to occur during FCoE initialization. This process discovers the VLAN that should be used to send all other FIP traffic during the initialization. This same VLAN is also used by FCoE encapsulation. The FIP VLAN Discovery protocol is the only FIP protocol that runs on the native VLAN.
FCF Discovery finds forwarders that can accept logins. FIP FCF Discovery is typically the second discovery process to occur during FCoE initialization. This process enables ENodes to discover FCFs that allow logins. FCFs that allow logins send periodic FCF Discovery advertisements on each FCoE VLAN.
Fabric Login (FLOGI) and Fabric Discovery (FDISC) messages comprise the final protocol in the FCoE FIP initialization process. These messages are used to activate Open Systems Interconnection (OSI) network model Layer 2, or the Data link layer, of the fabric. It is at this point in the initialization process that an FC ID is assigned to the N port, which is the port that connects the node to the switch.
