5.3.5 Monitor Ports Detailed Statistics

The Detailed Port Statistics page provides detailed traffic statistics for a specific switch port. To display the specific switch port details select the desired port from Port drop down box. For example, in following figure Port 6 is selected. The displayed counters are the totals for receive and transmit, the size counters for receive and transmit, and the error counters for receive and transmit.

Figure 5-13. Detailed Port Statistics

The Detailed Port Statistics page has the following parameters:

  • Receive Total and Transmit Total
    • Rx and Tx Packets: The number of received and transmitted (good and bad) packets
    • Rx and Tx Octets: The number of received and transmitted (good and bad) bytes. Includes FCS but excludes framing bits
    • Rx and Tx Unicast: The number of received and transmitted (good and bad) unicast packets
    • Rx and Tx Multicast: The number of received and transmitted (good and bad) multicast packets
    • Rx and Tx Broadcast: The number of received and transmitted (good and bad) broadcast packets
    • Rx and Tx Pause: A count of the MAC Control frames received or transmitted on this port that have an opcode indicating a PAUSE operation
  • 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
    • 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 1 frames received with valid CRC
    • Rx Oversize: The number of long 2 frames received with valid CRC
    • Rx Fragments: The number of short 1 frames received with invalid CRC
    • Rx Jabber: The number of long 2 frames received with invalid CRC
    • Rx Filtered: The number of received frames filtered by the forwarding process. Short frames are:
      • 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
  • Transmit Error Counters
    • 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
  • Receive MM Counters
    • Rx MM Fragments: A count of received MAC frame fragments
    • Rx MM Assembly OK: A count of MAC frames that were successfully reassembled and delivered to MAC
    • Rx MM SMD Error: A count of MAC frames with reassembly errors. The counter is incremented when the ASSEMBLY_ERROR state of the Receive Processing State Diagram is entered.
  • Transmit MM Counters
    • Tx MM Fragments: A count of transmitted MAC frame fragments
    • Tx MM Hold: A count of times MM_CTL.request (HOLD) primitive assertion caused preemption of a preemptable MAC frame
