Table 2-13 LRE Enet Stats on CPE Field Descriptions for LRE and CPE Interfaces
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 for which the first transmission attempt on an interface is not successful. This
value excludes frames in collisions.
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 multicast frames, broadcast frames,
and incorrectly formed frames.
