Receive and Transmit Size Counters
The number of received and transmitted (good and bad) packets split into categories based on their respective frame
sizes.
Receive and Transmit Queue Counters
The number of received and transmitted packets per input and output queue.
Receive Error Counters
Object Description
• Rx Drops
The number of frames dropped due to lack of receive buffers or egress
congestion.
• Rx CRC/Alignment
The number of frames received with CRC or alignment errors.
• Rx Undersize
The number of short frames received with valid CRC.
• Rx Oversize
The number of long frames received with valid CRC.
• Rx Fragments
The number of short frames received with invalid CRC.
• Rx Jabber
The number of long frames received with invalid CRC.
• Rx Filtered
The number of received frames filtered by the forwarding process.
Short frames are frames that are smaller than 64 bytes.
Long frames are frames that are longer than the configured maximum
frame length for this port.
1 Short frames are frames that are smaller than 64 bytes.
2 Long frames are frames that are longer than the configured maximum frame length for this port.
Transmit Error Counters
Object Description
• Tx Drops
The number of frames dropped due to output buffer congestion.
• Tx Late/Exc. Coll.
The number of frames dropped due to excessive or late collisions.
