Description
The count of transmitted octets that had no errors.
The count of transmitted frames that had no errors.
The total number of well-formed broadcast packets transmitted by
the port. It excludes packets received with errors or with multicast
destination addresses.
The total number of well-formed multicast packets transmitted by
the port. It excludes packets received with errors or with multicast
destination addresses.
Register that tracks all MAC transfer errors on the interface.
The total number of packets that failed to be sent after 16 collisions.
It includes packets of all destination address types.
Number of received MAC control frames that have an opcode
different than 00-01.
Number of flow control frames sent undersize
Number of good flow control messages received
Indicates the number of times the port RxFifo has reached full level
and at least one packet was dropped
Number of undersize frames received (valid packet with length less
than 64 bytes).
Number of fragments received on this interface.
Number of oversized frames received on this interface.
Number of jabber packets received (packet length is greater than the
MRU, and there is an invalid CRC, and no Rx Error event).
Number of Rx Error events seen by the receive side of the MAC (the
Rx Error signal/symbol was asserted while the frame is being re-
ceived).
The number of frames received with bad CRC.
Note
The total number of packets sent without error after having 1 to 15
collisions. It includes packets of all destination address types and
excludes packets discarded because of insufficient resources or late
collisions
The total number of packets discarded because of late collisions
detected during transmission. It includes all transmit packets that
had a collision after the transmission of the packet's 64th byte. The
preamble and SFD are not included in the frame's byte count.
Number of frames dropped due to the broadcast/multicast rate limit.
SPI-4/1 receive frame count. This counter increments once for every
Start of Packet (SOP) delineation marker sent on the SPI-4.2 receive
interface.
Note
Chapter 3 Cisco CRS-3 Carrier Routing System Router Command Changes
Collisions and late collisions apply to only half duplex
mode.
Packets that come from the CPU are not counted.
