Status Monitoring and Statistics
• Transmit Deferred Frames (TX Deferred) —
The total number of frames that were transmitted by
the port after the first transmission attempt was deferred by other network traffic.
• Transmit Errored Frames (TX Error) —
The total number of frames that were not completely
transmitted by the port because of network errors (such as late collisions or excessive collisions).
• Transmit Parity Frames (TX Parity)
— The bit summation has a parity mismatch.
To view port receive errors, use the following command:
show ports <portlist> rxerrors
The following port receive error information is collected by the switch:
• Receive Bad CRC Frames (RX CRC) —
The total number of frames received by the port that were of
the correct length, but contained a bad FCS value.
• Receive Oversize Frames (RX Over) —
The total number of good frames received by the port
greater than the supported maximum length of 1,522 bytes.
• Receive Undersize Frames (RX Under) —
The total number of frames received by the port that were
less than 64 bytes long.
• Receive Fragmented Frames (RX Frag)
— The total number of frames received by the port were of
incorrect length and contained a bad FCS value.
• Receive Jabber Frames (RX Jab) —
The total number of frames received by the port that was of
greater than the support maximum length and had a Cyclic Redundancy Check (CRC) error.
• Receive Alignment Errors (RX Align) —
The total number of frames received by the port that
occurs if a frame has a CRC error and does not contain an integral number of octets.
• Receive Frames Lost (RX Lost) —
The total number of frames received by the port that were lost
because of buffer overflow in the switch.
