> # ISL's Statistics

> Field | Description
> --- | ---
> Description | An alias name for the interface, as specified by a network manager. For Port Channel and FCIP, this field will always show members if they are available. For FCIP, this field will show compress if compressed.
> VSAN(s) | VSAN membership.
> Mode | Operating mode of the port> (See Legend).
> Connected To | Attached port. This could be a host, storage, or switch port.
> Speed | Maximum bandwidth in Gbps.
> Rx | One of the following: Utilization % Number of Bytes Number of Frames Average Frame Size
> Rx Comp | The IP Copmression ratio for received packets on the FCIP device.
> Tx | One of the following: Utilization % Number of Bytes Number of Frames Average Frame Size
> Tx Comp | The IP Copmression ratio for transmitted packets on the FCIP device
> Errors | Total number of Rx and Tx errors on the interface. Types of Rx errors include CRC errors, fragmented framed, unsupported class frames, runt frames, jabber frames, and giant Frames. Types of Tx errors are generally CRC errors, but these are rare. If the Errors field is not empty, there are probably Rx errors. For a more detailed breakdown of the error count, check the Monitor dialog box for appropriate interface.
> Discards | Total number of Rx and Tx discards on the interface. Rx frames discarded are generally due to protocol errors. On rare occasions, a frame is received without any hardware errors, but a filtering rule set for the MAC address discards the frame due to a mismatch. Discarded Tx frames can be timeout frame discards (port is offline or not up), or timeout frames that are not sent back to the supervisor (class F/2 frames). If the Discards field is not empty, it is probably due to timeout frames.
> Log | If checked, writes the record into the message log on each poll interval.
