FLOGI Parameters: Explanation

FLOGI (Fabric Login) is the process by which an N_Port (host/storage HBA) registers with a Fibre Channel fabric to receive fabric services and a Fibre Channel address (FCID).

Note: The right-side descriptions are not shown in your question, so the explanation below covers the standard technical derivation for each parameter's placement.

Parameter Placements Explained

1. nWWN (Node World Wide Name)

• What it is: A globally unique 64-bit identifier for the entire HBA node (the adapter card itself), not a specific port.
• Derived from: The HBA manufacturer's burned-in node identifier (OUI + vendor-assigned value), formatted as an NAA (Name Authority) identifier.
• Key point: One nWWN per physical adapter, shared across all ports on that adapter.

2. IP address

• What it is: A Layer 3 network address - relevant in FCoE (Fibre Channel over Ethernet) environments.
• Derived from: The management or data network configuration (DHCP or static), not from the FC fabric itself.
• Key point: IP addressing is an FCoE/iSCSI concern, not native FC - this is a common misconception area.

3. fWWN (Fabric Port World Wide Name)

• What it is: The WWN of the F_Port (fabric switch port) that accepts the FLOGI.
• Derived from: The fabric switch itself - assigned to the switch port, not the host.
• Key point: The f stands for Fabric. Students often confuse fWWN with pWWN - fWWN belongs to the switch side, pWWN belongs to the host side.

4. Symbolic Node Name

• What it is: A human-readable ASCII string that identifies the node in the fabric name server.
• Derived from: Host software/OS configuration - typically the hostname or a manually set string.
• Key point: This is optional and configurable; it has no hardware basis and is not globally enforced for uniqueness.

5. pWWN (Port World Wide Name)

• What it is: A globally unique 64-bit identifier for a specific port on an HBA.
• Derived from: The HBA port's burned-in address (OUI + port-specific vendor value). In FCoE, it can be derived algorithmically from the MAC address.
• Key point: A dual-port HBA has one nWWN but two pWWNs. This is the most commonly tested distinction.

Common Mistakes

The core principle: WWNs are hardware-derived (burned-in OUI), symbolic names are software-configured, IP addresses come from network config, and fWWN comes from the fabric/switch - not the initiator.
