Table 2-30 Receive Field Descriptions
Field Description
Bytes The total amount of memory (in bytes) used by frames received on an interface, including the
FCS
1
value and the incorrectly formed frames. This value excludes the frame header bits.
Unicast frames The total number of frames successfully received on the interface that are directed to unicast
addresses.
Multicast frames The total number of frames successfully received on the interface that are directed to multicast
addresses.
Broadcast frames The total number of frames successfully received on an interface that are directed to broadcast
addresses.
Unicast bytes The total amount of memory (in bytes) used by unicast frames received on an interface, including
the FCS value and the incorrectly formed frames. This value excludes the frame header bits.
Multicast bytes The total amount of memory (in bytes) used by multicast frames received on an interface,
including the FCS value and the incorrectly formed frames. This value excludes the frame header
bits.
Broadcast bytes The total amount of memory (in bytes) used by broadcast frames received on an interface,
including the FCS value and the incorrectly formed frames. This value excludes the frame header
bits.
Alignment errors The total number of frames received on an interface that have alignment errors.
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.
Oversize frames The number of frames received on an interface that are larger than the maximum allowed frame
size.
Undersize frames The number of frames received on an interface that are smaller than 64 bytes.
Collision fragments The number of collision fragments received on an interface.
Minimum size frames The total number of frames that are the minimum frame size.
65 to 127 byte frames The total number of frames that are from 65 to 127 bytes.
128 to 255 byte frames The total number of frames that are from 128 to 255 bytes.
256 to 511 byte frames The total number of frames that are from 256 to 511 bytes.
512 to 1023 byte frames The total number of frames that are from 512 to 1023 bytes.
1024 to 1518 byte frames The total number of frames that are from 1024 to 1518 bytes.
Overrun frames The total number of overrun frames received on an interface.
Pause frames The number of pause frames received on an interface.
Symbol error frames The number of frames received on an interface that have symbol errors.
Invalid frames, too large The number of frames received that were larger than maximum allowed MTU
2
size (including
the FCS bits and excluding the frame header) and that have either an FCS error or an alignment
error.
Valid frames, too large The number of frames received on an interface that are larger than the maximum allowed frame
size.
Invalid frames, too small The number of frames received that are smaller than 64 bytes (including the FCS bits and
excluding the frame header) and that have either an FCS error or an alignment error.
