FDDI Applications

Statistics are displayed in three ways:

By count (i.e., the number detected of each for the selected interval).

By rate (i.e., the number of each per second, as averaged over the selected interval).

Graphically, as a percentage of each with respect to total network load processed by the HSIM-F6 during the last interval.

You can view the concentrator performance for three different intervals:

Absolute – Counts recorded since the device was last started.

Cumulative – Counts recorded since the Concentrator Performance window was opened.

Delta – Counts recorded during a single polling interval that is set for NetSight Element Manager (refer to the User’s Guide).

To change the interval, click to select the desired radio button in the Count Display panel in the top right hand corner of the window.

Available statistics are:

Transmit Frames

The number of frames transmitted by the HSIM-F6’s MAC during the selected interval.

Receive Frames

The number of frames received by the HSIM-F6’s MAC during the selected interval.

Frame Errors

The number of error frames detected by the HSIM-F6’s MAC during the selected interval that had not been detected previously by other stations. Error frames may include frames with an invalid Frame Check Sequence (FCS), with data length errors, or with internal errors that prevent the MAC from transferring the frame to the Logical Link Control (LLC) layer.

Lost Frames

The number of frames detected by the HSIM-F6’s MAC during the selected interval that have an unknown error, so their validity is in doubt. When the HSIM-F6’s MAC encounters a frame of this type, it increments the Lost Frame counter and strips the remainder of the frame from the ring, replacing it with idle symbols.

Ring Ops

The number of times the ring has entered the “Ring Operational” state from the “Ring Not Operational” state during the selected interval. This counter updates when the HSIM-F6’s MAC informs Station Management (SMT) of a change in Ring Operation status.
