Fibre Channel ports overview
Fibre Channel (FC) ports provide the ability to connect a Brocade VCS Fabric cluster to a Fibre Channel switch in a Fabric OS network.
The FlexPort feature is the only method that a switch running Network OS 5.0.0 or later can connect FC ports. For instructions on how to use FlexPort, refer to the "Configuring FlexPort" chapter of the Network OS Layer 2 Switching Configuration Guide.
The following platforms are Flexport-capable:
- Brocade VDX 2740
- Brocade VDX 2746
- Brocade VDX 6740
- Brocade VDX 6740T
- Brocade VDX 6740T-1G
These connections can be regular but not long distance. The following Network OS Fibre Channel port types are supported:
- E_Port: Can be used to connect only to an EX_Port on a FC SAN with Fibre Channel Routing configured.
NOTEYou must enable fcoeport default for the interface for the Fibre Channel logins to be available to connect to F_Ports.
Supports FC target connectivity (standards based F_Port).
Supports bidirectional traffic internally from VF_Port, or internal ISL port.
- Auto (G_Port) — This is the default.
Default port type in Access Gateway mode
Available in Access Gateway mode only
Supports bidirectional traffic internally from VF_Port.
External connection to F_Port on a FC SAN
- For FCoE initiator or target connectivity.
Supports bidirectional traffic internally to E_Port, F_Port, VF_Port (all in FCF mode), and N_Port (in AG mode).
- Using an Inter-Switch Link (ISL) connection from an FC E_port on a Flexport-capable switch to a FC router's EX_Port; this in turn connects to the FC switch in the Fabric OS network. The VDX FC ports are configured as E_Ports for this connection. Refer to Connecting to FC Fabric through FC Router.
- Using a direct connection from an FC port on a Flexport-capable switch to an F_Port on a FC router in a Fabric OS network. The VDX FC ports are configured as N_Ports through the Access Gateway feature. Refer to Using Access Gateway.
