Port Errors
The switch keeps track of errors for each port.
To view port transmit errors:
Use the following command:
show ports txerrors
The following port transmit error information is collected by the
system:
❑ 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) — The total number of
collisions that have occurred after the port’s transmit window
has expired.
❑ Transmit Deferred Frames (TX Def) — 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 Err) — The total number of
frames that were not completely transmitted by the port
because of network errors (such as late collisions or excessive
collisions).
