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.
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
