Description
The total number of frames received on an interface that have a valid length (in bytes) but do not
have the correct FCS values.
The number of frames received on an interface that are larger than the maximum allowed frame
size.
The number of frames received on an interface that are smaller than 64 bytes.
The number of collision fragments received on an interface.
The total number of frames that are the minimum frame size.
The total number of frames that are from 65 to 127 bytes.
The total number of frames that are from 128 to 255 bytes.
The total number of frames that are from 256 to 511 bytes.
The total number of frames that are from 512 to 1023 bytes.
The total number of flooded frames received on an interface.
The total number of overrun frames received on an interface.
The total number of frames that are filtered because of the VLAN information in the frame, such
as an IEEE 802.1Q tag or a VLAN ID other than the IDs configured on the interface. This value
does not include frames that are smaller than 64 bytes or larger than the maximum frame size
The total number of frames received on an interface that are dropped because the source route bit
is set in the source address of the native frame. This value includes frames that have a valid FCS
value and are between 64 bytes and the maximum allowed frame size.
The number of frames received on an interface that are larger than the maximum allowed frame
size and have valid FCS values. The frame size includes the FCS value but does not include the
VLAN tag.
The number of pause frames received on an interface.
The number of frames received on an interface that have symbol errors.
The number of frames received that were larger than maximum allowed MTU
the FCS bits and excluding the frame header) and that have either an FCS error or an alignment
error.
The number of frames received on an interface that are larger than the maximum allowed frame
size.
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.
The number of frames received on an interface that are smaller than 64 bytes (or 68 bytes for
VLAN-tagged frames) and have valid FCS values. The frame size includes the FCS bits but
excludes the frame header bits.
