> # FC Interfaces General

> The following variables are not supported by all interfaces: PortVSAN, Port Mode Admin and Oper, Admin Speed, and FailureCause.

> Field | Description
> --- | ---
> Description | Alias name for the interface as specified by a network manager.
> VSAN Id Port | VSAN ID to which this interface is statically assigned.
> VSAN Id Dynamic | The VSAN ID that this interface has been dynamically assigned (see DPVM).
> CDP (Enable) | An indication of whether the Cisco Discovery Protocol is currently running on this interface.
> Promiscuous Mode | Checking or unchecking this option dictates the destination of the packets/frames. If this option is checked, then this interface accepts packets/frames that are addressed to this station. If this option is not selected, then packets accepted by the station are transmitted on the media. Checking or unchecking this option does not affect the reception of broadcast and multicast packets/frames by the interface9.
> Auto Negotiate | An indication of whether auto-negotiation of speed and duplex mode should be used on this interface.
> Beacon Mode | In beacon mode, an interface LED is assigned a flashing mode for identification. Select this option to enable beacon mode.
> Mode Admin | The port mode configured by the user. Modes are: auto - If the user configured the port as auto, then the port initialization scheme determines the mode of the port. F Port - In fabric port mode, an interface functions as a fabric port. This port may be connected to a peripheral device (host or disk) operating as an N port. FL Port - In fabric loop port mode, an interface functions as a fabric loop port. This port may be connected to one or more NL ports (including FL ports in other switches) to form a public arbitrated loop. E Port - In expansion port mode, an interface functions as a fabric expansion port. This port may be connected to another E port to create an Inter-Switch Link (ISL) between two switches. E ports carry frames between switches for configuration and fabric management. FX Port - Interfaces configured as Fx ports can operate in either F port or FL port mode. The Fx port mode is determined during interface initialization depending on the attached N port or NL port. This administrative configuration disallows interfaces to operate in any other mode—for example, preventing an interface to connect to another switch. SD Port - In SPAN destination port mode, an interface functions as a switched port analyzer (SPAN). The SPAN feature is specific to switches in the Cisco MDS 9000 Family. It monitors network traffic that passes though a Fibre Channel interface. TL Port - In translative loop port mode, an interface functions as a translative loop port. It may be connected to one or more private loop devices. TL port mode is specific to Cisco MDS 9000 family switches and have similar properties as FL ports. ST Port - In the SPAN tunnel port (ST port) mode, an interface functions as an entry point port in the source switch for the RSPAN Fibre Channel tunnel. The ST port mode and the remote SPAN (RSPAN) feature are specific to switches in the Cisco MDS 9000 Family. When configured in ST port mode, the interface cannot be attached to any device, and thus cannot be used for normal Fibre Channel traffic. TE Port - In trunking E port mode, an interface functions as a trunking expansion port. It may be connected to another TE port to create an Extended ISL (EISL) between two switches. TE ports are specific to Cisco MDS 9000 family switches. B Port - While E ports typically interconnect Fibre Channel switches, some SAN extender devices, such as Cisco's PA-FC-1G Fibre Channel port adapter, implement a bridge port model to connect geographically dispersed fabrics. The oper mode on this port type is "read only" and it cannot be set. TF Port - Trunking f_Port TNP Port - Trunking N Proxy port mode applicable only to N-port Virtualizer (NPV) NP Port - N Proxy port mode applicable only to N-port Virtualizer (NPV)
> Mode Oper | The current operating mode of the port.
> SpeedGroup | Specifies the current speed group configuration on the given interface. None—The interface speed group configuration on this interface is not applicable. It is a read-only value. 10G—The interface speed group configuration on this interface is 10G. 1/2/4/8G—The interface speed group configuration on this interface as 1G-2G-4G-8G.
> Speed Admin | The port speed configured by the user. The port speed values are auto, 1Gb, 2Gb, 4Gb, 8Gb, 10Gb, autoMax2G, and autoMax4G. Note On a Cisco Nexus 5000 Series switch that runs Cisco NX-OS Release 4.2(2), you can configure the 8-Gbps administrative speed only on an M1060 switch module. You can configure the speed to 1 Gbps, 2 Gbps, or 4 Gbps on all switch modules on a Cisco Nexus 5000 Series switch that runs Cisco NX-OS Release 4.2(2) or earlier releases.
> Speed Oper | Operational speed.
> RateMode | Specifies the interface as dedicated mode or shared mode.
> Status Service | Specifies whether the interface is in service or out of service.
> Status Admin | The desired state of the interface.
> Status Oper | The current operational state of the interface.
> Status FailureCause | The cause of current operational state of the port.
> StatusWasEnabled | If true, this port successfully completed a link initialization.
> Status LastChange | When the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this value is N/A.
> Port Owner | Administratively assigned name of the current owner of the interface resource.
