Description
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.
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.
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.
The total number of frames received on an interface that have alignment 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.
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 overrun frames received on an interface.
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 that have valid FCS values. The frame size includes the FCS bits but
excludes the frame header bits.
The number of frames dropped on the ingress port because the packet aged out.
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.
