Table 2-12 LRE Enet Stats on Switch Field Descriptions
Field Description
Transmit
Bytes The total number of bytes sent on an interface.
Frames The total number of frames sent on an interface.
Pause frames The number of pause frames sent on an interface.
1 collision frames The number of frames that are successfully sent on an interface after one collision occurs.
Multiple collisions The number of frames that are sent after more than one collision occurs.
Late collisions After a frame is sent, the number of times that a collision is detected on an interface later than 512
bit times.
Excessive collisions The number of frames that could not be sent on an interface because more than 16 collisions occurs.
Deferred frames The number of frames that are not sent on an interface.
Carrier sense errors The number of frames with carrier sense errors.
Receive
Bytes The total amount of memory (in bytes) used by frames received on an interface, including the FCS
value and the incorrectly formed frames. This value excludes the frame header bits.
Frames The total number of frames received on an interface, including broadcast frames and incorrectly
formed frames.
Broadcast frames The total number of frames successfully received on an interface that are directed to broadcast
addresses.
Pause frames The number of pause frames received on an interface.
Alignment errors The total number of frames received on an interface that have alignment errors.
Collisions and Runts The number of frames that could not be received on an interface because of collisions because the
frame length (in bytes) is too small.
Receive
Oversize frames The total number of frames that are the larger than the maximum allowed frame size.
FCS errors The total number of frames received on an interface that have a valid length (in bytes) but do not
have the correct FCS values.
