Table 5-8. LAN Errors Statistics Parameters (Cont.)
Parameter Possible Values / Remarks
Tx & Rx Errors
Internal Mac Transmit Errors The number of frames for which transmission to selected interface fails due
to internat MAC sublayer transmitt error.
Internal Mac Receive Errors The number of frames for which transmission to selected interface fails due
to internat MAC sublayer receive error.
Deferred Transmissions The number of frames for which first transmission attemp on selected
interface delayed due to the media bing busy.
Carrier Sense Errors The number of time that carrier sense condition was lost or never asserted
when attempting to trasmit frames on selected interface.
Collisions
Single Collision Frames The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
Multiple Collision Frames The number of successfully transmitted frames for which transmission is
inhibited by more than one collision.
Late Collisions The number of times that a collision is detected on selected interface later
than 512 bit-times into the transmission of a packet.
Excessive Collisions The number of frames detected on selected interface that failed due to
excessive collisions.
The following group statistics can also be displayed in a graph:
• Packets
• Octets
• Error Frames
• Tx & Rx Errors
• FCS & Test Errors
• Collisions.
