Setting the Time Interval, Frame Errors | Cabletron Systems 2.2

FDDI Applications

Frame Errors

The number of error frames detected by the FDDI BRIMÕs 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 FDDI BRIMÕs MAC during the selected interval that have an unknown error, so their validity is in doubt. When the FDDI BRIMÕs 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 ÒRing OperationalÓ state from the ÒRing Not OperationalÓ state during the selected interval. This counter updates when the FDDI BRIMÕs MAC informs Station Management (SMT) of a change in Ring Operation status.

Setting the Time Interval

You can change the time interval during which the performance statistics are collected. To do so, click to select the desired option button in the Count Display panel (in the top right hand corner of the window):

¥Absolute Ñstatistical counts recorded since the FDDI BRIM was last started.

¥CumulativeÑstatistical counts recorded since the Performance window was opened.

¥DeltaÑstatistical counts recorded during a single polling interval that is set for SPECTRUM Element Manager (refer to the SPECTRUM Element Manager UserÕs Guide for more information).
