The Summit keeps track of errors for each port.
To view port transmit errors, use the following command:
show port <portlist> txerrors
The following port transmit error information is collected by the switch:
• 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).
To view port receive errors, use the following command:
show port <portlist> rxerrors
