The switch keeps track of errors for each port.
To view port transmit errors, use the following command:
show ports <portlist> txerrors
The following port transmit error information is collected by the system:
• Port Number
• Link Status — The current status of the link. Options are
— Ready (the port is ready to accept a link)
— Active (the link is present at this port)
• Transmit Collisions (TX Coll) — The total number of collisions seen by the port,
regardless of whether a device connected to the port participated in any of the
collisions.
• Transmit Late Collisions (TX Late Coll) — The total number of collisions that have
occurred after the port’s transmit window has expired.
• 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
