> Field | Description
> --- | ---
> Description | An `alias' name for the interface as specified by a network manager.
> Mtu | The size of the largest frame which can be sent/received on the interface, specified in bytes.
> Speed Oper | Operational speed of the interface.
> PhysAddress | The interface's MAC address.
> Status Admin | The desired state of the interface.
> Status Oper | The current operational state of the interface.
> 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.
> 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 interface.
> Beacon Mode | In beacon mode, an interface LED is assigned a flashing mode for identification. Select this option to enable beacon mode.
> IPAddress/Mask | IP address and subnet mask for the interface.

> Note SAN Admin users cannot change the ethernet interfaces settings in Cisco Nexus 5000 Series switches using Device Manager.
